How to connect LED strips


Connecting LED strips – couplings, connectors, soldering

LED strips offer great design options. However, some lighting installations require connecting multiple sections of LED strips. The LED strips can be connected to each other with special accessories or with a soldering iron.

Connect LED strips in series or parallel

LED strips can be combined with each other in two ways: in series and in parallel.

Series connection: The series connection of LED strips consists of connecting consecutive strip sections together. This connection method is recommended for short strip sections.

Parallel connection: With this connection, each section of the strip is connected directly to the power supply. This type of connection prevents voltage drops.

Connecting longer sections of LED strip

Sections longer than 5 m should not be connected to each other – such a connection can cause voltage drops. Connecting the LED strips to a power supply should be done according to the diagram:

How to connect an LED strip without soldering

To connect sections of LED strips without soldering, use special connectors or couplers designed for this purpose LED strips. They enable quick and easy assembly without a soldering iron. When choosing the connectors, pay attention to the width of the LED strip and its type. Some connectors are for single color strips, others for RGB or RGBW strips.

Connection/coupling for LED strips
LED strips can be connected by soldering, connections, or couplings. The connections or couplings should be selected correctly according to the strip type (eg RGB) and its width.
Coupling variants: Single color
LED strips: 8mm, 10mm  
RGB strips: 10mm
RGBW strips: 10mm, 12mm Angle
connector: allows strips to be connected at an angle

How to connect LED strips in silicone

LED strips with increased IP protection are secured with a silicone coating. To connect these strips, carefully remove the silicone layer from the connection point and then use a connector or coupler to connect the two sections of the LED strip.

How to solder LED strips?

Another way to connect LED strips is soldering.

Solder led strips

To start, you need to prepare:
– transformer-soldering iron
– solder
– strips or wires for soldering

1. Preheat the soldering iron (the temperature should be in the range of 320-380°C)
2. Bring the tin to the designated places of the LED strip
3. Connect the dots with the applied tin in a horizontal motion
4. Wait a few seconds for the tin to cool.

How to solder LED strips in silicone?

To join sections of the waterproof LED strip by soldering, carefully remove the silicone layer and then solder the LED strips together at the appropriate locations. Use a clear shrink fitting to protect the solder joint. It is worth remembering that the light from the LEDs is slightly dimmed in the place where the connector is located.

How to cut LED light strips

How to cut led strips

LED strips can be conveniently cut very easily. So you can bring your LED strips to the desired length for every location. But be careful! The LED strip may only be cut at a few specific points, otherwise, it will remain dark afterwards. Here you can find out what you have to pay attention to when cutting the LED strip and how you can connect them again.

Part 1: Cutting LED strips

Q: Can you cut LED light strips? How to cut LED light strips?

A: Since an LED strip light is fixed in length and it is not always possible to purchase a suitable length strip light, users often ask if an LED strip light can be cut to a specific length. There are many different brands and LED strips, so the question of whether a strip can still be used normally after cutting cannot be answered in general. It really depends on the product in question. In general, if the strip has a cutting line, it can be trimmed; if not, it’s best not to cut them.

How to cut led strips

Before you cut the strips it is important to check that the strip you have purchased can be cut; otherwise the strips could become unusable. At the same time, it is imperative that you remember to turn off the electricity. Directly cutting a strip connected to the power supply is extremely dangerous.

Step 1: Measure length

If the LED strip you bought is too long, you need to cut off the extra part. The first thing you should do is measure the right length so you don’t cut the strips too short.

Step 2: Find the scissors icon on the strip

For the convenience of users, manufacturers have included a scissor logo on the cuttable portion of their LED light strips. To avoid damage, you must find the scissors logo before you cut.

Step 3: Cut with scissors

The final step is to cut off the excess strip with scissors at the point marked with scissors. Accidentally cutting diagonally can cause the strips to stop working. So make sure you cut straight.

Part 2: Using the LED strips after cutting

Q: I bought a LED strip and used part of it. But I also want to use the remaining part. Is that possible?

A: If the LED strip you bought can be cut, the leftover cut-off can no longer be used. If you want to reconnect them after cutting, you will need to use an extra 4-pin connector to reconnect them. However, if the cutting and termination are done improperly, it can cause the strips to stop working properly. It is therefore advisable to double-check the length of the strip before cutting so that it does not have to be reconnected after cutting.

If you need to reconnect LED strips after cutting, you need an additional 4-pin connector. In general, this product is not included in a LED strip kit and must be purchased separately.

Step 1: Buy a suitable 4 pin connector

There are many different connectors and you need to choose the right one depending on the strip. If your strip is 10mm wide, the 4-pin connector you choose must be suitable for 10mm. If your strip is 8mm wide and you buy a 10mm connector it will not work.

Step 2: Open connector

If the connector has a cover, you need to open the connector sideways.

Step 3: Insert strip into connector

Place the two cut ends of the LED strips in the connector’s fastening clips. At this point, check that they are not swapped by following the picture guide.

Step 4: Cover connectors

After attaching the strips, close the connector cover and check if the light strip lights up normally after connecting the power supply. If the connected parts do not light up normally, then you should try to adjust the connection point between the connector and the strip.

Connection of the LED strips after cutting

In general, it is a bit tedious to reconnect the light bar after cutting it off. Not only do you have to buy additional connectors, but any mishandling can render the strips unusable. It is therefore best to ensure that the required length is correct and avoid waste.

Part 3: Using the LED strips after cutting

Q: Will a cut LED strip still work?

A: Some strips can be cut to a specific length and continue to work. However, they must be cut according to the cutting mark. There are small and very precise parts on LED strips. Accidentally cutting in the wrong place can cause the strips to stop working properly.

After cutting the strips, you can put the corresponding parts in the right position and turn on the lights by following the steps below.

Step 1: Make sure the wall is dry and clean

If you want to install the strips on a wall, please clean the wall first. If the wall is dusty or wet, the LED strip cannot be fixed properly.

Step 2: Attaching the LED strips

After cleaning the wall, you can peel off the film behind the strip and stick it where you want.

Step 3: Connect the LED strips

If you bought a LED strip, it should come with a connector and a controller. Connect the strips and the controller using the connector. Pay attention to the front and back when connecting the strips and connector. If the light strip is plugged in the wrong way, it will not work properly.

Step 4: Connect power supply and turn on LED strip

The last step is to connect the controller to the power supply. The LED strip should light up.

After following the steps above and noticing that the LED strip is still not lit, you should check if there is a connection problem. If set up correctly, it is possible that the light strip was damaged during cutting. So be careful and always cut according to the logo on the strip.

LED strips: flexible lighting solutions

Modern Living Room And Television Set At Night With Neon Lights
Modern Living Room And Television Set At Night With Neon Lights

LED strips are a great way to create the right mood lighting for any room because the lighting in a room has a significant impact on how it affects people. The choice of lamps and illuminants is therefore important when it comes to the interior design of your own four walls. The diverse designs of LED strips enable a wide variety of lighting concepts.

Function and light colors of LED light strips

From diffuse to brightly lit in changing colors, the setting options seem endless. The flexible LED strips can be found in a wide variety of areas, across all rooms and furniture – both indoors and outdoors – with very individual solutions for all objects.

Basically, LEDs create a beautiful glow in a room by running electricity through semiconductor technology, which then produces infrared and ultraviolet light. The small lights are attached to their circuit boards at regular intervals on a band. The individual lamps are connected to each other with a wire.
The type of semiconductor crystal used or its composition in the lamp determines the wavelength of the light, which results in the color generated:

light colorWavelength in nanometers (nm)  
Rot 640–780    

White light is created from the sum of all wavelengths, it does not have a dedicated wavelength of its own. For this reason, the color temperature, which is specified in Kelvin (K), is used to describe white light. There are generally three types of white light:

  • Warm white: 2700 to approx. 3300 Kelvin
  • Neutral white: approx. 3500 to 5300 Kelvin
  • Daylight white (also known as cold white): from approx. 5300 Kelvin 

The different shades of white in LED light strips, just like bright colors, have a direct impact on the feeling and effect of the room. The less Kelvin the white light has, the greater the red, orange, and yellow components in it. In addition to relaxing brightness, an LED strip in warm white ensures a cozy, homely ambiance. Conversely, the higher the Kelvin number, the bluer the white contains. It approaches daylight and has a stimulating and concentration-enhancing effect.

The color rendering, which describes the quality of artificial light in the form of the color rendering index Ra, must be distinguished from the color temperature. With a higher CRI (Colour Rendering Index), objects look more natural. While the incandescent lamp with a CRI of up to 100 was the standard for a long time, white LEDs now also achieve a value of up to 98 and are in no way inferior to the old light sources.

The amount of light emitted by a source per unit of time, on the other hand, is measured in lumens. On the other hand, the unit Lux indicates how bright it is, i.e. how much light arrives on a surface per unit of time.

The variety of LED strips

Above all, the versatility of the LED strips has made the small light-bringers so popular. Each room can be embellished and individualized with different lighting concepts. In order to meet this requirement, we offer you LED strips in various shapes, colors and designs:

  • RGB LED strip
  • RGBW/RGBWW LED strips
  • waterproof LED strips
  • battery-powered LED strips
  • COB LED strip
  • LED strips in a set with power supply and dimmer

All stripes can be individually adapted to your own requirements. You can choose the strip length between 5 centimeters and 5 meters for almost all strips. Some models are even available up to 10 meters long. A fundamental distinction is that either one row or two rows of lights are attached to a strip. According to your wishes, you can buy your perfectly matching LED strips in our online shop.

Color splendor with LED strips RGB, RGBW and RGBWW

What do the abbreviations actually stand for? one might ask at first. The explanation is very simple. The letters RGB stand for the colors of the additive color system that can be displayed by the LED strips, and the W or WW designates an additional white light-emitting diode, which can either be installed in the same housing or externally. Basically, RGBWW stripes define the warm white color temperature of the additional diode. At a glance, the LED strips with the 4-in-1 chip can produce the following colors:

  • Rot
  • Green
  • Blau
  • White
  • Warm white 

A corresponding remote control, also known as an RGB(W) controller, is required to select the individual colors. This is used to control the LED strips. They are all dimmable via the remote control. In addition, transitions can be set at variable speeds, alternating flashing is also possible. The specified color options can also be mixed using the remote control. As a result, your room lights up individually in the color you want.
Depending on the color, a room looks completely different. Orange tones are ideal for the dining room, for example, because they look friendly and create a cozy atmosphere. Yellow lighting evokes associations with sunlight and promotes receptivity, creativity, and joie de vivre.

Green, on the other hand, is the color for nature, calm, and relaxation. If your relaxation room shines with green light accents, the respiratory rate is lowered, the pulse rate calms down and you can relax better. Blue is associated with water, sea, sky, and a calming expanse. This has a positive effect on concentration and reduces mental restlessness.
The most diverse effects can be achieved with the brightly colored RGB stripes. From accent spots on certain pieces of furniture or the backlight on a TV to full ceiling lighting, the strips work wonderfully in a variety of areas.

Waterproof stripes for inside and outside

Waterproof means that moisture cannot get into the lights and therefore cannot cause any damage. The LED light strips get this property from their design. Thanks to a special silicone layer and the appropriate covers, no moisture can get to the sensitive technology. The areas of application, therefore, extend from within your own four walls to outdoors. They are just as insensitive to rain as they are to the water in the pond and pool or moisture in the bathroom. The garden can be wonderfully illuminated with waterproof lights. Be sure to pay attention to the corresponding IP protection class of the LED strips. Stripes are protected against spray water from IPX4. For permanent operation underwater, however, you need at least protection class IPX8.

In our wide range of high-quality products, you will certainly find the right LED strips for your purposes.

Simplicity reigns supreme with Quick LED strips

High light requirement, variability, easy cleaning, and, on top of that, simple assembly. We are talking about the Quick LED light strips. Quick refers to the assembly properties of the stripes. They can be plugged together indefinitely because the power supply is linear and passed from band to band. Only the power supply has to be readjusted, because the more LEDs on the light strip, the more power is required.

One strip is connected to the next via the 4-pin Quick-Connect socket. Several meters of the stripes can be joined together using a 4-pin connector. The distance between the individual lights remains the same with this type of connection. If a strip is to be shortened, this is always possible at a distance of 0.125 meters at marked points. The protective silicone layer must be removed when shortening the new end of the strip so that the cable or plug can be soldered on again.

Everything was included in one fell swoop: in the LED strip set

Whether large areas, entire rooms, or smaller elements, the areas of application of the complete sets are as varied as the colors of the LEDs. The biggest advantage of a set is the extensive package content:

  • LED light strips
  • connection cable
  • power adapter
  • remote control 

All the technology required for assembly, installation, and operation arrive in your home in one fell swoop. You don’t have to worry about whether the power supply has to be 12 volts or 24 volts because the right piece is included. It is perfectly adapted to the included strip and controller. The individual parts are simply plugged together in just a few minutes and the technology is ready for use. Greater effort and more intensive work only arise if the strip is shortened.

Installation – it’s that easy

A decision was made:  LED strips on top of the kitchen cupboards are to expand the lighting concept as an additional light source. Despite the main lighting from wonderfully bright spotlights in the kitchen on high-traffic areas, it is still a little too gloomy. The necessary length of the strip has already been determined, it should be 4.10 meters, with a double row of LEDs.

To solder or not to solder?

The next decision is whether or not special cabling is required. For the former, many of the strips can be ordered without connectors, which means that the power supply and connection cable have to be soldered on yourself. For the second there are pre-soldered sockets. Connection cables can simply be plugged into these.

Once this question has been answered, it is time to choose the right power supply unit. Depending on the strip length, the watt consumption per meter, and the required voltage in volts, an appropriate power supply must be selected. The most common are LED strips with 12 V and LED strips with 24 V. LED strips with 230 V are ideal if a very long strip is to be installed, for example.

Simply glue on the LED strips

As soon as the required technology has been purchased and is on-site, the actual assembly can begin. Thanks to a practical double-sided adhesive tape, only the foil needs to be removed from the back of the LED strip. Then the bulb can be glued to the desired location. However, the surface should first be clean and dust-free, otherwise cleaning is the first thing to do.
Once the strip has found its place and is glued, it is connected to the cable and power supply. The power pack is plugged into the socket and the kitchen shines in new splendor – just as desired.

Special lighting for individual styles

Regardless of the shape, whether for angles, corners, or simply along a line – LED strips are a lighting solution for so many areas of application that impress with their efficiency and flexibility. To expand existing lighting concepts or in the form of accent lighting, there is hardly an easier way to get modern lighting technology into your own four walls. In addition to the well-known energy efficiency of LEDs, easy assembly and installation are additional cherries on top of the cream.

Ready configured light strips as an alternative

In contrast to loosely attached LED strips, light sources that are permanently installed in a profile are protected against impact and the ingress of dust and moisture. Depending on the profile, passive cooling through the dissipation of heat can also be an advantage of these light strips. If you want to create indirect lighting in the living room through a suspended ceiling or illuminate stairs, you don’t have to do without flexibility.

LED lighting for the right lighting mood

Led Lighting Mood

With the right mood lighting, you create a special atmosphere for different requirements. A cozy seating area requires a different lighting mood than the study or bathroom. In fact, the right light not only creates the right mood but can also influence well-being and even health. Here you can find out what needs to be considered for optimum lighting.

What is the lighting mood?

The lighting mood is an interplay of the type of lighting, the color temperature and the brightness. In general, a cozy lighting mood is distinguished from a neutral or rather cool lighting mood. The different aspects of the lighting in a room create a very individual lighting atmosphere. For this reason, while there is no magic recipe for an optimal result, there are a few tips that you can follow to create the desired mood.

Mood depending on the area of ​​application

The use of a room or area is often decisive for the desired atmosphere. For example, different lighting is required in the study or in the kitchen than in the living room or bedroom. A ceiling light is often sufficient for functional lighting, but the right lighting atmosphere can only be achieved through a harmonious mixture of different types of lighting. A distinction is made between the following types of lighting for your home lighting concepts:

  • basic lighting
  • indirect lighting
  • accent lighting
  • working lights 

Each type of lighting has specific properties, making it suitable for different areas.

Basic lighting

Basic lighting is usually used in the form of a ceiling light. It ensures that a room is illuminated over a wide area and ideally it is dimmable so that you can change the lighting mood in no time at all.

Indirect lighting

Indirect lighting can be achieved, for example, with LED strips behind furniture or above a false ceiling, but also with spotlights aimed at a wall. Indirect light does not cast any shadows and provides even, cozy illumination – the perfect addition to the basic lighting.

Accent lighting

Lamps and spotlights can be used for accent lighting to illuminate special pieces of furniture or decorative elements and thus set the scene.

Working lights

Work lighting is used wherever concentration is required or there should be sufficient brightness for certain activities – for example in offices or in the kitchen.

It’s all in the mix

The right lighting mood is often only achieved through a combination of several types of lighting – an interplay of diffuse and spotlighting makes a room look cozy and at the same time sets exciting accents.

Rooms or areas that are used for different activities at different times pose a particular challenge. Ideally, the various types of lighting can be combined in different ways or are dimmable in order to create a different mood with little effort. For example, the same area can be illuminated brightly enough for a meal with friends to set the scene for the meal in an atmospheric way, but later accompany a movie night with a more cozy lighting atmosphere.

The Effect of Light

The lighting in a room not only provides sufficient light for various activities, but also for a certain lighting mood that can directly influence our mood. On the one hand, colors can have a certain effect on us in the sense of color therapy, on the other hand, even minimal gradations of brightness and/or color temperature can have a decisive influence on our well-being. The right lighting can even support the biorhythm and vice versa, unfavorable or even wrong lighting can disturb it.

Lighting mood and biorhythm

The day and night rhythm in particular is controlled by the hormone melatonin, which is produced to a greater or lesser extent depending on the intensity and color temperature of the light. For example, subdued light with a low blue content ensures increased production, and the body is prepared for a restful sleep – which is why melatonin is also called the “sleep hormone”. During the day, bright light with a high proportion of blue – ideally daylight – reduces the release of the hormone: we are awake, alert, and concentrated.

Color temperature

Modern LED lamps are available in different light colors. The light color is also referred to as color temperature and is given in Kelvin (K). A basic distinction is made between these color temperatures:

  • Warm white: below 3,300 K
  • Neutral White: 3300K – 5300K
  • Daylight white: over 5,300 K

In general, the lower the temperature, the redder the light appears. Above a temperature of 5,300 K, the light appears increasingly bluish as the temperature rises.

Colored light by RGB lights

With RGB LED lights, you can set a specific color to achieve a very specific lighting mood. We know from color therapy that green light, for example, has an activating effect and can promote creativity. This makes it ideal for work and living rooms.

Yellow light, on the other hand, has a relaxing effect and can be used, for example, after a long day to recharge your batteries. Orange or red have a calming effect and are a good alternative to dimmed white light, especially in the evening. Incidentally, when used sparingly, red light can stimulate the senses and promote activity.

More tips for mood lighting

The right choice of lamps is important for the lighting atmosphere. In addition to the desired light color, luminous efficacy and brightness are also crucial aspects. Depending on the area of ​​application, you should also make sure that the LED light is dimmable or that the light color can be adjusted. When setting up or attaching the lights, care should be taken to avoid dazzling – including indirectly through reflections, for example in panes.

The beam angle of the LED lighting – this is important to note

Beam Led Angle

In addition to the watt and lumen specification, there is an additional value that is decisive for the choice of an LED: the beam angle. It has a significant effect on how brightly the lamp and spotlight illuminate a surface. We have summarized for you what you need to know about the beam angle of your LED lighting.

The angle allows the right light in the room

Different lamps fulfill different tasks in interior design: the basic lighting ensures pleasant room lighting, accent lighting can be used to create beautiful eye-catchers and decorative lighting sets the scene for the valuable wall art.

So that the different light installations do not get in each other’s way, it is important to consider the beam angle of the built-in LED lamps. This prevents the light cones from overlapping and there are no overexposed areas in the room. However, before you can take this into account, you have to know what exactly is meant by the term beam angle of an LED.

Beam Angle vs. Field Angle: What’s the Difference?

Basically, it is important to pay attention to the beam angle for every type of LED, regardless of whether a ceiling light or an LED spot is used for lighting. As far as the angle is concerned, however, it makes sense to differentiate between a directional light source and an omnidirectional light source. The classic light bulb, for example, is a round radiator that distributes its light in all directions and only gets a certain direction through a lampshade. A directional illuminant, on the other hand, shines in a precise direction. The LED in its various forms such as spot, radiator, or bar belongs to the second category.

The beam angle, which is specified in degrees, determines the angle at which a luminous flux emerges from a light source.

The beam angle of an LED is decisive for how the light is thrown into a room. Together with the distance between the lamp and the ground, a circle of light is created. The greater the distance between the ceiling and the lamp, the larger the area covered by the circle of light. However, not every area covered by the circle of light achieves the same brightness. The spread of the light is responsible for this. In order to describe this effect, the term field angle was introduced in addition to the radiation angle. In some descriptions of the beam angle, the term half-power angle is used. In fact, these are just two terms for the same phenomenon.

The range of the beam angle reaches up to 50% of the luminous intensity of an LED. However, only a maximum of 10% of the luminous intensity of a spotlight or a ceiling light reaches the area of ​​the field angle that surrounds the beam angle area.

Even when a light source is aligned, there is always some degree of light scattering. The full 100% light intensity is only effective in the central point of the light cone. The further away you are from this center, the less light intensity and thus brightness get from the light source into the room.

Especially with accent and decorative lighting, which are implemented with LEDs, attention must be paid to the right beam angle. So you are on the safe side to illuminate the desired object appropriately. The following table is used to illustrate the relationship between the diameter of the circle of light and the half-value angle. As the average ceiling height of new buildings is between 2.3 and 2.5 meters, the table assumes a ceiling height of 2.4 meters.

Diameter of light circle (in meters)beam angle  
0,6 15°  
1,3 30°  
2,0 45°  
2,8 60°  
4,8 90°  

It becomes apparent that the half-value angle of an LED has a significant influence on the actually illuminated area of ​​a room. The larger the angle selected, the larger the area covered by the light from the illuminant.

Calculate the beam angle of an LED yourself

If you already know two important key data – the diameter of the required light cone and the distance between the lamp and the illuminated surface – you can calculate the half-power angle yourself without much effort.

a = 2 x {arctan [d / (lx 2)]} is the formula for calculating the beam angle. The arctan is the inverse of the tangent used in calculating angles. On most calculators, it is marked with the arctan key.

The value a represents the beam angle of your LED to be calculated. The value designates the diameter of the required light cone or the area to be illuminated. The distance between the lamp and the surface is marked with the value l. If you insert the last two values ​​into the formula, the beam angle required for your desired LED is calculated. Unnecessary bad purchases of the wrong LEDs can be easily avoided.

Brightness, beam angle, and LED bulbs

The lumen value of LEDs is an indicator of how bright the light from the light source is. The larger the value, the brighter the respective lamp can shine. With two identical lamps with different beam angles, the perceived brightness is very different.

When choosing an LED light source, it is not only important to pay attention to the values ​​of lumen and beam angle, but also to the interaction between the two factors.

A lamp with a half-power angle of 15° and one with a half-power angle of 60°, which have the same lumen value, have the same light output on paper. However, the 60° light source covers a much larger area with its circle of light than the 15° lamp can. The larger area in this example will be less brightly lit than the smaller 15° fixture if both fixtures are mounted at the same height.

Can the beam angle of an LED be edited afterward?

Sometimes you want a change in your own four walls and the interior needs to be adjusted. This also includes the lighting. In this case, the structure of an LED cannot be changed later. But what about the beam angle? To reduce the angle, one immediately thinks of an improvised lampshade. Quickly crafted, it invites you to live out your creativity. Attaching a diffuser comes to mind to increase the angle.

The beam angle of LED lamps cannot be reduced or increased by hand. Modifications carried out independently can lead to heat build-up, burns through, or even fires.

If you are not satisfied with the half-power angle of your LEDs, we recommend purchasing a new one. Thanks to the lower power consumption and the comparatively low acquisition costs, the replacement is worthwhile. It’s also the safest course of action, both for you and your belongings. You can save yourself the costly conversion work by a specialist. The old bulbs can easily find a new place of use elsewhere in the apartment.

The purpose of use also decides on the beam angles

The lighting of living spaces serves different purposes. That’s why we offer a wide variety of light sources, from recessed lights to spotlights and strips to modules. The LEDs in different sizes can be used for any purpose:

  • accent lighting
  • decorative lighting
  • basic lighting

With basic lighting, you want to bathe a room in bright light over as wide an area as possible. In living rooms such as bedrooms or living rooms, a large beam angle of 120° is ideal for LED lighting, so the light cone is very large.

Several 90° spots are ideal in narrower areas such as corridors. The beam angle of LED lighting for accent lighting or for decorative purposes is more dependent on two factors: the distance to the lamp and the size of the object to be illuminated.

Small key figure, big effect

Choosing the right half-power angle for your LEDs is immensely important. With the right values, wonderful worlds of light can be created in the home. Incorrectly selected angles lead to the opposite, glare effects or corners that are too dark can occur. Therefore, keep in mind the factors of intended use, the distance between the lamp and the illuminated area as well as the size of this area when purchasing new LED lamps that have an optimally selected beam angle.

What are LEDs?


LED, in full light-emitting diode, in electronics, is a semiconductor device that emits infrared or visible light when charged with an electric current. Visible LEDs are used in many electronic devices as indicator lamps, in automobiles as rear-window and brake lights, and on billboards and signs as alphanumeric displays or even full-colour posters. Infrared LEDs are employed in autofocus cameras and television remote controls and also as light sources in fibre-optic telecommunication systems.

The familiar lightbulb gives off light through incandescence, a phenomenon in which the heating of a wire filament by an electric current causes the wire to emit photons, the basic energy packets of light.

LEDs operate by electroluminescence, a phenomenon in which the emission of photons is caused by the electronic excitation of a material. The material used most often in LEDs is gallium arsenide, though there are many variations on this basic compound, such as aluminium gallium arsenide or aluminium gallium indium phosphide. These compounds are members of the so-called III-V group of semiconductors—that is, compounds made of elements listed in columns III and V of the periodic table. By varying the precise composition of the semiconductor, the wavelength (and therefore the colour) of the emitted light can be changed.

LED emission is generally in the visible part of the spectrum (i.e., with wavelengths from 0.4 to 0.7 micrometres) or in the near-infrared (with wavelengths between 0.7 and 2.0 micrometres). The brightness of the light observed from an LED depends on the power emitted by the LED and on the relative sensitivity of the eye at the emitted wavelength. Maximum sensitivity occurs at 0.555 micrometre, which is in the yellow-orange and green region. The applied voltage in most LEDs is quite low, in the region of 2.0 volts; the current depends on the application and ranges from a few milliamperes to several hundred milliamperes.

The term diode refers to the twin-terminal structure of the light-emitting device. In a flashlight, for example, a wire filament is connected to a battery through two terminals, one (the anode) bearing the negative electric charge and the other (the cathode) bearing the positive charge. In LEDs, as in other semiconductor devices such as transistors, the “terminals” are actually two semiconductor materials of different compositions and electronic properties brought together to form a junction. In one material (the negative, or n-type, semiconductor) the charge carriers are electrons, and in the other (the positive, or p-type, semiconductor) the charge carriers are “holes” created by the absence of electrons.

Under the influence of an electric field (supplied by a battery, for instance, when the LED is switched on), current can be made to flow across the p-n junction, providing the electronic excitation that causes the material to luminesce.

In a typical LED structure, the clear epoxy dome serves as a structural element to hold the lead frame together, as a lens to focus the light, and as a refractive index, match to permit more light to escape from the LED chip. The chip, typically 250 × 250 × 250 micrometres in dimension, is mounted in a reflecting cup formed in the lead frame. The p-n-type GaP:N layers represent nitrogen added to gallium phosphide to give green emission; the p-n-type GaAsP:N layers represent nitrogen added to gallium arsenide phosphide to give orange and yellow emission; and the p-type GaP:Zn,O layer represents zinc and oxygen added to gallium phosphide to give red emission.

Two further enhancements, developed in the 1990s, are LEDs based on aluminium gallium indium phosphide, which emit light efficiently from green to red-orange, and also blue-emitting LEDs based on silicon carbide or gallium nitride. Blue LEDs can be combined on a cluster with other LEDs to give all colours, including white, for full-colour moving displays.

So to answer what are LEDs exactly, any LED can be used as a light source for a short-range fibre-optic transmission system—that is, over a distance of fewer than 100 metres (330 feet). For long-range fibre optics, however, the emission properties of the light source are selected to match the transmission properties of the optical fibre, and in this case, the infrared LEDs are a better match than the visible-light LEDs. Glass optical fibres suffer their lowest transmission losses in the infrared region at wavelengths of 1.3 and 1.55 micrometres.

To match these transmission properties, LEDs are employed that are made of gallium indium arsenide phosphide layered on a substrate of indium phosphide. The exact composition of the material may be adjusted to emit energy precisely at 1.3 or 1.55 micrometres.

LED Strips: 5 tips for a cozy living room

Living Room Interior At Night With Sofa, Floor Lamp, Potted Plants And Neon Lighting

For many people, the living room is the most important room in the house or apartment. There you can rest and relax after a hard day. In the living room, they watch films, listen to music or receive guests. Accordingly, the room should be furnished and illuminated particularly attractively. The appropriate LED lighting ensures the latter.

But what exactly should it look like? What should be considered when planning LED lighting? At LED Strips World, we know exactly what is important when it comes to the lighting concept. Therefore, we give you five tips below on how to optimally illuminate your living room with LED strips and lamps. But first, we want to clarify why it should be LED lighting at all.

What distinguishes LED lighting in particular?

The classic light bulb has long had its day. The LED has been on the rise for years – and for several good reasons. One of the most important is the low energy consumption of LEDs. Compared to other lamps, LED lights to consume up to 80 percent less electricity.

In addition, LEDs are very durable. LED Strips World’s QLF Pro Strips, for example, have an operating life of 200,000 hours. This means that they will remain bright and colorfast for six decades of normal use.

Another positive aspect is that the LED lighting shines in full brightness immediately after switching on. LEDs do not have start-up time, as is the case with energy-saving lamps, for example. Modern LED lamps are also dimmable, which significantly expands the possibilities of use.

With our five helpful tips, we will tell you how best to equip your living room with LED lighting.

Tip 1: Plan enough light sources

Basically, there should be a central light source in the living room that illuminates the entire room. It is usually located on the ceiling. There are also lamps that are attached to the wall or placed in the room. However, they run the risk of unsightly shadows if furniture or other objects are in the way of the light.

For the ceiling, the following types of lamps are particularly popular:

ceiling spotlight
pendant lamp

A ceiling spotlight often consists of several lamps that shine in different directions. This means that the entire room can be supplied with light evenly. A chandelier looks particularly elegant but represents a rigid light source. A pendant light also only distributes its light in one place. It should therefore have a shade that distributes as much light as possible in the room.

To create coziness in the living room, it is worth using a ceiling lamp with a dimming function. This allows you to darken the room if necessary and thus ensure a relaxed atmosphere.

If the living room has a crooked floor plan, then the use of different light sources is even indispensable. Walls could ensure that not every corner of the room is illuminated with a single lamp. In this case, there should be several strong light sources in the living room.

Suitable light sources for different areas of the living room

In addition to the central ceiling lamp, the living room should also have other lamps. These should be chosen according to the activity that is commonly practiced in their area.

In a reading corner, for example, there should be as strong a light source as possible. This protects the eyes when reading. The Cosmic floor lamp from LED Strips World, for example, is well suited. It is 180 centimeters high, has 576 LEDs, and emits up to 8000 lumens. It not only illuminates the pages of a book, but also a room of up to 50 square meters.

When watching TV, on the other hand, a rather weak light is desired. It serves exclusively as an additional light source to relieve the eyes. Lamps or LED strips that are located behind the TV set are well suited for this.

If there is a dining table in the living room, it should have its own light source. A lamp hanging above the table is common. It provides sufficient light for everyone who dines at the table. The dining table lamp should also be dimmable. So it can be set to a weaker light if you are sipping wine after the meal.

Tip 2: Cold or warm light

When choosing lamps for the living room, the light temperature plays a decisive role. It is given in Kelvin and is decisive for whether the light is perceived as warm or cold. The following values ​​make the difference:

less than 3300 Kelvin: warm white light
between 3300 and 5300 Kelvin: neutral white light
more than 5300 Kelvin: cold white light

For comparison: a candle glows with 1500 Kelvin, daylight with 5500 to 7000 Kelvin.

Warm white light has a relaxing effect. So if you want to create a cozy atmosphere in the living room, you should use lamps with less than 3300 Kelvin primarily. This is a signal to your body that it can relax.

The situation is different when the living room is sometimes also used as a workplace. Then at least the lamps near the work table should emit cold white light. It promotes concentration, which is quite desirable at work. This also applies to the reading corner. After all, you want to be able to concentrate while reading and not constantly run the risk of falling asleep while reading.

However, the general lighting concept in the living room should still be warm white, since the room is primarily used for relaxation. A good compromise is neutral white light. It has an activating effect and creates a functional and at the same time cozy atmosphere.

Change the light temperature by dimming

If you opt for dimmable LED lighting in the living room, you do not have to commit to a specific light temperature. Rather, you change them according to the activity you are currently doing.

The LED strips in our QLF series can be set to light temperatures between 2200 and 6500 Kelvin. In the low range, they produce a warm white light that invites you to relax. In the high range, they provide cold white light. This makes them suitable for the reading or working area in the living room.

Tip 3: Discreet or indirect lighting thanks to LED strips

In addition to light sources that illuminate the entire living room, the use of hidden lights is also recommended. They ensure comfort in a special way, as their light is very subtle. The best option is LED strips like those from our QLF series.

They are equipped with 200 LEDs per meter and thus provide even light over a longer length. They can be attached to the edges of furniture, for example. On the underside of the sofa or above the wall unit, the LED strips create a special atmosphere. They can also be attached very well to stairs and increase safety there.

Indirect light can also be generated with LED strips. This is light that bounces off the wall or ceiling. For example, if you attach an LED strip behind the television, it only illuminates the wall behind it. However, the light is reflected and creates a cozy atmosphere.

Can be cut individually

The LED strips in our QLF and QLF Plus series can be individually adapted to your needs. Depending on the model, they can be cut every ten to 75 millimeters. All you need is standard household scissors. Afterward, the LED strips are of course still fully functional. Thanks to the cut, they are always exactly as long as you want them to be.

The same applies to the products in our QLP series. They are LED modules that transform entire wall surfaces into light sources. They can be cut every 48 millimeters and therefore also fit exactly into the space provided.

The LED modules generate a brightness of 30,000 lumens per square meter and make every living room shine. Since they are dimmable, their light intensity can be easily adjusted to the situation.

Tip 4: Highlight special objects with lighting

In every living room, there are objects that the residents are particularly proud of. This can be, for example, a mural by a well-known artist or a large-format family photo. Decorative objects or collectibles in a showcase also want to be admired. The right lighting literally puts them in the right light.

A spotlight aimed directly at the special object emphasizes its great importance. The luminaire can be a spotlight from the ceiling lamp or a light specially installed for the object. When guests enter the room, thanks to the light, their eyes immediately fall on the special object. The lamp also creates an interesting lighting atmosphere during a cozy get-together.

Tip 5: Lamps are not only a source of light but also a decoration

When furnishing your living room, you should not neglect the lighting. This does not only refer to the conception of the light, which we have explained to you so far. It’s also about the look of the lamps themselves. If they are appealing, they give the room that certain something.

This is possible, for example, with our already mentioned Cosmic floor lamp. Their design is timeless and based on the high-quality look of Apple products. This decision is not accidental. The product is compatible with Apple’s HomeKit. This means that it can be operated with the iPhone, the iPad, or via voice control with the HomePod.

Another design trick is the lack of a light switch. The built-in acceleration sensor detects the movement and carries out the desired action.

In addition, the innovative technology developed by Apple, Adaptive Lighting, is used in Cosmic. It ensures that the color temperature of the light automatically adapts to that of the environment. A built-in microprocessor also reduces the flickering of the lamp by clocking 170 million times per second.

Cosmic is also capable of glowing in millions of colors. Would you like to bathe your living room in an idyllic blue or in a romantic red? Or should it rather be a cold white light so that you can read with concentration? The decision is entirely yours.

In any case, the lamp offers you countless possibilities to make yourself comfortable in your living room.

Dispose your old LED strips properly

LED Strip Lighting
LED Strip Lighting

LED bulbs represent an immense advance and are far superior to conventional light bulbs and other lamps. They last much longer, consume hardly any electricity, and can be individually adjusted in color and brightness.

Lamps that use the new LED technology have a service life of at least 15,000 hours. Many LED Strips World products far exceed this value and are designed for a service life of 200,000 hours.

Despite everything, it sometimes happens that LED bulbs fail and disposal is necessary. For example, in this article, you will learn how to identify defective lamps and where to take them.

How do LED strips work and what advantages do they offer?

LED lamps consist of semiconductor components and produce tiny flashes of light (photons). The color of the LEDs can be adjusted as desired by simply controlling the amount of energy. The functional principle is therefore significantly more complicated, but also more efficient than with normal light sources. In contrast to a light bulb, there is hardly any waste heat.

Because of these unique advantages, LEDs are superior to incandescent bulbs, for example, in many respects. Because they consist of permanently mounted electronic components, they last much longer than, say, a filament. The power consumption is also much lower as the energy output is concentrated on the light. Incandescent bulbs, on the other hand, generate far more heat than light.

In addition, they inherently contain a dimming function and are capable of rendering many different colors. Compared to energy-saving lamps, they also have the advantage that they are immediately bright and contain no toxic ingredients.

How can I tell that an LED light source is no longer working properly?

Led strip coil on dark background. Led shining diodes background.

Normal light bulbs have many disadvantages. However, it is very easy to see whether they still work or not. The bulb simply no longer lights up, and the filament inside usually shows visible damage.

With LED lamps, however, it is much more complicated to determine whether there is a defect. The lamps do not have a filament, but light-emitting diodes. Depending on the error present, these show various signs of damage.

As with the incandescent lamp, an LED lamp is always defective if it no longer lights up. A weaker light or a changed color also indicates that the lamp is not working properly.

The reason for the failure is also not easy to identify. In light bulbs, as a rule, the filament burns out. This happens in particular when the lamp is switched on. However, LED lamps are more similar to computers than normal lamps in terms of how they work. They consist of a large number of technical components.

The light-emitting diode itself is only defective in exceptional cases. If the lamp does not work properly, this is often due to an error in the electronics. However, this is often not visible to the naked eye.

Therefore, pay attention to whether the lamp is unusually dark or changes color. If the condition does not improve over time, everything indicates that the lamp is damaged beyond repair. In this case, it is time to dispose of the LED bulb.

What should be considered when disposing of LED lamps?

LED Strips recycle

If light bulbs or halogen lamps are defective, disposal is extremely easy. Thanks to their simple construction, they can be thrown away with household waste. They consist only of glass and metal and contain no environmentally harmful or particularly valuable components.

Due to their technical components, LED lamps are classified as electronic waste. In addition, they contain many special materials that do not belong in household waste. In this respect, they can be compared to energy-saving lamps and fluorescent tubes, which also do not belong in the dustbin.

As with all illuminants, a glass container is out of the question for disposal. Lamps are made of a different kind of glass than mason jars and bottles, for example. Among other things, the melting point of these is significantly lower than that of lamps. This property leads to a considerable additional effort when recycling since the types of glass differ too much from one another.

Dealing with old LED light sources is very easy if you do not regard the lamp as a classic light source. Just treat them like a broken electronic device. The lamps can be disposed of in the same way. You can therefore hand them into a retail store or recycling center free of charge, just like conventional electronic devices.

Why is it important to dispose of LED bulbs correctly?

There is usually a good reason for the time-consuming disposal of certain components. Energy-saving lamps and fluorescent tubes included for example dangerous and environmentally harmful elements such as mercury. In order to protect the environment, it is therefore important that the lamps do not end up in normal household waste. Under certain circumstances, mercury causes considerable damage in nature and pollutes the groundwater, for example.

With LED lamps, the reason for the special disposal is different. The lamps are made of the following materials:

  • 88 percent glass
  • 7 percent different metals
  • 7 percent other materials

The metals it contains, such as indium and gallium, are very rare and are used in many electronic devices.

The useful raw materials of the lamps are lost in household waste and cannot be reused. It is also not ideal for the environment if the substances end up in a normal landfill.

8 Advantages of LED strips that you should know

For a long time, incandescent lamps were the only light source. Energy-saving lamps and halogen lamps were added later, but some of these brought new disadvantages. Only with lighting based on LEDs is there a real alternative to light bulbs on the market. LED lights last longer and use much less energy.

They also offer many interesting additional functions. For example, they glow in any color or can simply be stuck to the wall or furniture as a band.

The past without LED strips

The invention of the lightbulb represented a tremendous advance in the 19th century. It burned much brighter than any candle, oil, or gas lamp. She was also much less dangerous. The light bulb was then an integral part of our lives for many decades. We accepted the disadvantages of this meanwhile outdated technology.

A regular replacement of the bulbs was a matter of course and part of everyday life. The fact that a lightbulb generates far more heat than light also seemed normal for a long time. Smaller explosions, in which the room was subsequently littered with glass splinters, were also not uncommon.

In order to save energy and protect the environment, the first attempts were finally made to develop alternative light sources.

Halogen bulbs use less power than an incandescent bulb and last twice as long. However, they still require a lot of energy. The glass bulb of the lamp heats up to around 250 degrees Celsius. It therefore also generates much more heat than light. In addition, the durability is not significantly higher than that of incandescent lamps. Here, too, the regular exchange is necessary.

Energy-saving lamps made it possible to save a significant amount of electricity. However, they possessed a number of new problems. In contrast to other lamps, they are not immediately bright. Instead, it sometimes takes up to five minutes before they reach their full potential. As a result, many people left the lamps on longer than necessary to benefit from full brightness. This eliminated the energy-saving effect.

In addition, energy-saving lamps contain mercury and many other toxic substances. They can therefore not be disposed of normally with household waste. In addition, they pose an enormous health risk during operation and especially when they fall.

In summary, it can be said that neither halogen lamps nor energy-saving lamps offer real added value compared to incandescent lamps.

What are the advantages of LED strips?

Red led strip on the black background

The future of light sources only finally began with the invention of LED lights. Whether classic incandescent bulbs or energy-saving bulbs – LEDs surpass everything that has gone before.

These eight advantages distinguish LED lights from other light sources:

  • no delay when switching on
  • long durability
  • high efficiency
  • Low energy consumption
  • numerous colors possible
  • made of durable components
  • dimmable
  • no toxic ingredients

Below we briefly discuss each of these benefits.

Full light at the push of a button

Normal energy-saving lamps often need a long time before they reach their maximum brightness. They are therefore unsuitable for quickly illuminating a room. This is noticeable, for example, in basement rooms where people normally only stay for a short time. By the time you leave the room, the lamp is often not really bright.

LED modules, on the other hand, are immediately ready for use. They, therefore, offer the same luxury as incandescent or halogen lamps. In this way, rooms can be illuminated quickly and efficiently.

Very long lifespan

Another key benefit of LED lights is their durability. Running times of 15,000 hours are already part of the absolute minimum. There are hardly any upper limits. Many LED Strips World products even have a running time of 200,000 hours.

Conventional light bulbs only last about 1000 hours. Energy-saving lamps, for their part, have a service life of around 10,000 hours.

In contrast to incandescent lamps, LED lights can also be used after the end of their lifetime. While incandescent lamps usually give up surprisingly, LED lamps only shine weaker. The LED chip does not contain any components that no longer work due to a defect. In this way, LED lights can continue to be used many years after the end of their lifetime.

Hardly any heat emission

Although LED lights are very bright, they hardly give off any heat. This distinguishes them from incandescent lamps or halogen lamps. These are often so hot during operation that there is a risk of burns.

A light bulb emits around 95 percent of the energy it uses in the form of heat. A lot of energy is lost as a result. In addition, with light bulbs, it is always important to ensure that there are no flammable materials nearby.

LED lights, on the other hand, use almost all of the energy to generate light and are therefore much more efficient than other light sources. There is also no risk of burns or damage to other objects. The temperature of the lamps usually corresponds to that of the body.

Significantly lower energy consumption

Therefore, LED lights require much less power than other lamps to achieve the same brightness. The difference between light bulbs is up to 80 percent. Even compared to energy-saving lamps, lamps with LEDs require 50 percent less electricity. Especially with regard to the environment, LEDs are the light source of the future and offer maximum efficiency.

The low power consumption is also quickly apparent in relation to the performance of the lamps. For example, LED lights require eight watts for the same amount of light and a normal incandescent lamp requires 60 watts.

Any color possible

3d render, abstract neon background, virtual reality tunnel, ultraviolet spectrum, fashion catwalk podium, empty performance stage, floor reflection

In contrast to conventional lamps, LED lights are extremely diverse and available in numerous colors. Whether yellow, red, or blue – the lamps shine in every imaginable color. So-called RGB lights can also be individually adapted to your own mood. So they always shine in the right color.

Robust construction

Conventional lamps are often very sensitive to shock. If they fall, they are usually unusable. LED lights, on the other hand, impress with their insensitivity to shocks and vibrations of all kinds. For this reason, they are ideally suited for mobile use. Important areas of application are, for example, bicycle lights, flashlights as well as machine and vehicle lights.

Easily dimmable

LED lights can be easily dimmed. You can even change the color or color temperature if you wish. This is made possible by the so-called pulse width modulation (PWM). The technology benefits from the fact that LEDs can be switched on and off without any problems. This enables high frequencies without damaging the lamps.

Good for people and the environment

In addition to the lower energy consumption, LED lights also make an important contribution to the environment due to their composition. Classic energy-saving lamps contain extremely harmful mercury. It is, therefore, necessary to dispose of them as hazardous waste after use. With LED lights, on the other hand, disposal as normal electronic waste is possible. In addition, individual components are increasingly being reused.

In terms of health, energy-saving lamps are also the worse choice, as there is always a risk that toxic mercury vapors will be released. Even with the normal operation of such lights, toxic substances get into the room air.

The implementation of exciting lighting projects requires only a few tools and some background knowledge. It is crucial that you get your LED strip to the right length. We will help you and have put together tips for using LED strips. Many users don’t even know that they can shorten an LED strip like our QLF Strips. Here you find out how this works.

Depending on the selected connection variant, the following tools are required to carry out the work:

• Scissors
• Cutter knife
• Click connector
• Solder set
• Heat shrink tubing

Basic information on changing an LED strip

Many LED strips can be flexibly changed in length. The products from LED Strips World are one of them. But how do you know whether changes to an LED strip are possible or not? To do this, you need to know that all LED strips consist of units and segments. The strips are usually delivered on rolls with several units. A unit is often around half a meter long.

The individual units can in turn be divided into segments. This is where you start if you want to shorten the LED strip. The segments are the smallest areas into which the units of our QLF LED strips can be divided. If you want to shorten your band, always cut exactly between two segments. This is how you get the function of the QLF Strips.

To make things easier for you, manufacturers mark the segments on the tapes for you. Exactly where this optical marking is placed always depends on the manufacturer and the respective product. A small symbol is usually printed at the point of separation. Cut right there and nowhere else.

As a general rule, always cut between the copper dots on the tape, but not through them. Because you will later make contact again at the copper points when you reconnect the LED strip. The copper dots must therefore remain undamaged. It is often possible to see these contact points through the slightly transparent material. Then you can’t go wrong.

Changing the LED strip: you need this

You do not need any special tools to cut through your LED strip. Simple household scissors are sufficient to cut through the material. Of course, you can also use a cutter. Ensure a straight cut and divide the ribbon in the middle of the dividing line. Then you won’t damage any important parts and the tape will remain fully functional.

With some LED strips you also have to remove silicone protection. You will find this in products with a higher degree of protection. A sharp blade is required for this job. Use a cutter or carpet knife. As always, the rule here is that you must not accidentally damage the traces.

You have to remove the silicone sleeve, otherwise, you won’t be able to solder. There must be no silicone residues on the copper areas. Check this carefully before proceeding to the next step. To remove the silicone protection, cut parallel to the PCB. The PCB is the part that has fine traces on it.

Once you have made the cut, you can carefully push the silicone forward and pull it off the PCB. In this work, it is important that the knife does not accidentally slip away from you. Once you have successfully removed the silicone protection, solder the sections of the LED strips together as desired.

What happens if I cut in the wrong place?

With a careless cut, you can quickly damage the LED strip, at least partially, and make it unusable. You may therefore only cut where small scissors, a dividing line, or other symbols and instructions are printed. If you cut somewhere else, the tape is unusable until the next segment. So be careful so you don’t have to throw away a LED strip.

If you make a mistake when cutting through, it can no longer be corrected afterward. You then have no choice but to dispose of the damaged segment. Knowledge of electrical engineering or tricks will no longer help here. Care is therefore particularly important in this work.

As mentioned above, LED strips with silicone protection are more difficult to process. You will find such an LED cover, for example, in products with protection class IP 20 or IP 65. These products are recommended because they are better shielded against environmental influences. This ensures trouble-free operation.

When does it make sense to connect LED strips together?

There are many reasons for connecting several small LED strips to form one large one. This gives you more options when it comes to designing the length and you can flexibly adjust the strap. The technique is also useful when you want to put a strip around the corner. For the various tasks, it is important to know how the connection of LED strips works.

One of the most important motives for disconnecting and reconnecting the LED strips is length adjustment. Only with a lot of luck will the tape cut off the roll be exactly the length you need. Knowing how to reconnect our QLF Pro Series products will give you a better handle on their length.

Ideally, make sure you know the length you need before you buy it. Even if the product you bought is not yet the perfect length, you can minimize waste in this way. This helps you to keep the acquisition costs low.

To measure exactly how long the tape needs to be. Use a tape measure for this and lay it the way you want your LED strip to be later. Then cut the LED strip at the point that comes closest to the desired length. This saves material and labor.

When determining the length you need, it is important to consider any edges and curves that the strip will follow. If you only measure roughly with a ruler, you may end up missing a little length.

A little trick: If you don’t have a measuring tape, you can also measure with a tape. Lay the tape in the desired place for the LED strip. Then use a ruler to measure the length of the tape. This will help you to order the LED strip in the correct length.

Bring LED strips to the right length for outdoor use

Shortening and connecting are also worthwhile for products such as our QLF Pro LED strips. Thanks to the use of our special ceramic chip technology, you can also use them outdoors.

How can I connect LED strips together?

There are basically two ways of connecting LED strips. You can either solder them together or use something called a click connector. Both approaches have their advantages and weaknesses.

The connection via a solder joint requires tools and certain technical skills. If you dare to place a solder joint, you will get clean and tightly connected strips. The connectors are recommended for less experienced users. They impress with their particularly easy handling.

If you already have soldering tools in your workshop, you don’t need anything else to connect via a solder joint. With the second variant, on the other hand, you first have to get the right-click connectors. After all, the acquisition costs for this are very low. In the following, we explain both procedures in detail.

This is how the connection is made using a click connector

A click connector is a simple tool for assembling LED strips. You can purchase click connectors in various designs in stores. It is particularly practical that many LED strips often come with the right connectors. Then no further purchases are required.

The connectors perform the simple task of bringing the traces of the two strips to be connected into contact with each other. They have corresponding contact pins for this. There are four of these pins in total. This corresponds to the four-conductor tracks of the LED strip.

It is important that the contact points can touch without interference. As already mentioned, silicone coatings must therefore be completely removed. The conductors of the LED strips are made of copper. Many manufacturers put four letters on the ladder to make it easier for you to tell them apart.

When making the connection, make sure that you place the four conductive paths precisely over the pins. Tracks and pins must touch to make contact. The connectors have a plastic tab for this. With the tracks correctly seated on the pins, press the tab onto the underside of the connector. You will feel it click into place if you have done everything correctly.

Make sure the copper traces are flush under the pins and that the poles are properly aligned. If the tracks are provided with letters, it is easy to connect them to each other without making mistakes. If you have problems, you should turn one of the strips over and reinsert it into the connector. The goal is to get the poles right.

What should I do if the LED strip does not light up after connection?

First, check whether you have actually cut the LED strips at the intended points. It is not possible to successfully separate the tapes elsewhere. If you have done everything correctly, you must check the connectors again. If the band does not light up, the pins are probably not making proper contact.

Each click connector has four pins. Make sure the traces are exposed and actually connected to the pins.

This is how the connection by solder joint works

It is also possible to solder the copper contact points of the LED strips together. This method is much more complex than the click connector, but the connection is much more solid afterward. Once a soldered connection has been made, it can only be separated willfully.

In addition, there is no click connector, the housing of which is relatively thick. If you don’t like the look of these connection points and they get in the way when laying, soldering is the better alternative.

Soldering is recommended for all users who are familiar with this technique and have the necessary tools. For soldering, you work with temperatures up to a maximum of 250 degrees Celsius. Nothing else is required for this task. It is important that you proceed cautiously. The LED strips are thin and delicate. You should also reduce the soldering time to a minimum.

Use the usual flux or solder to make the connection. After completing the work, you should insulate the soldered joint again. Use shrink tubing for this. This ensures that there are no problems during operation.

If you carry out the work correctly, it is hardly recognizable afterward that you have reconnected the LED strips. This is one of the key advantages of this technique. The straps look like you bought them that length. Visually you have a cleaner solution compared to the click connectors.

If problems occur during soldering, this is almost always due to unclean contact points. There are probably still silicone residues that you did not completely remove in the previous step. Carefully scrape off any silicone residue with a knife. You can use the LED strips successfully connected by soldering immediately for decoration.
