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.


  1. We are a group of highly qualified ethical hackers who scan tens of thousands of sites every day for critical vulnerabilities and patch them for a small fee.

    On your site – we have discovered 5 critical vulnerabilities, each of which can give attackers full access to your site, databases and the server as a whole.

    Pay $3000 (0.15 BTC) by visiting this site where you will be able to copy our bitcoin (btc) address or scan the QR code with your device
    And after payment within 12 hours we will fix all the vulnerabilities on your site and you can sleep peacefully without worrying about the safety of your site and server.

    If we are hired by well-known corporations, then we charge from $50000 for our services, so you are lucky that we offer you the same service for $3000 (0.15 BTC)

  4. We have hacked your website and extracted your databases. This was due to the security holes you had in your your site/server which have gained us remote control of pretty much everything that was on the server.

    Our team is mostly interested in customer, administrative, and employee information which we have extracted through your databases once we got remote control over the server. It still needs to be sorted out but it will be well-organized once finished. First, we will be going through the emails/sms information and contacting the recipient how you held in disregard about their information being exposed to a hacking group when you could have stopped it. This would be detrimental to your personal image with these relationships with these people. Lastly, now that we have information not only will we be monetizing off it with our methods but made public or sold to other people that will do whatever they wish with the information also after we are done.

    Now you can put a stop to this by paying a $3000 fee (0.11 BTC) in bitcoin to the address 39F2misMUWQ2Pt7PEuZLmJA1DaJHWnAVRL We will be notified of payment which we will then delete the information we have obtained, patch the hole in the site/server which we got in and remove you from any future targeting in the future. You have 72 hours in doing so after viewing this message or the series of steps will commence. You can obtain bitcoin through such services such as or do a search on
