How to Connect LED Lights Together?

LED strip lights are one of the best things that have happened in the world of lighting. You can use them to decorate your art, home, light up your kitchen counter, add as stair lighting or ceiling lighting for the festive season. Since they come in long strips, you can cut them into desired lengths and also connect them to increase the length. We already saw the answer to “can you cut strips of led lights?” in a previous guide. In this guide, we will see how to connect led lights together.


one of the main reasons for the popularity of led strip lights is that you can easily set the length of the strip you want. you can easily cut the led strip to fit perfectly on your kitchen counter or you can connect another strip to it to cover the entire ceiling during the holiday season.

LED strips are available in single color options (white, red, blue, etc.) where all the LEDs on the strip are the same color. They are also available as fancy RGB, where you can use a small remote control to set the color to your liking, adjust the brightness and also set different modes like fade, blink or leds on.

some led strips come with a weatherproof coating (some kind of silicone coating on top of the actual led strip to make it waterproof). you can use these strips outdoors with any weather concerns. there are led strips that are intended only for indoor use.

The most popular length for LED strips is 5m (just over 16ft). but you can also get smaller led strips (such as automotive led strips) or larger led reels that are over 50 feet long.

can you connect multiple led strip lights together?

The answer is yes. but there are some things you need to take care of. we’ll see them as we go along.

if you already cut the led strip before and you want to reconnect them to the same strip, then you don’t have to worry about anything else. all you have to do is follow any of the methods mentioned below and continue using the extended led strip lights.

obviously you can’t connect two different led strip i.e if one is single color led strip and the other is rgb led strip. In this case, the LED strips are completely incompatible with each other and cannot be connected to each other.

Another scenario is, if you have strips from two different brands, what do you do then? if they are compatible with each other, i.e. they both have the same design and both are rated for the same voltage, you can connect two different brand led strips together.

Voltage is another important thing to consider before connecting led lights. because some strips run on 5v dc while others run on the more popular 12v dc. there are strips that work with a higher voltage, like 24v, but 12v strips are extremely popular.

how to connect led lights together?

after making sure that the two led strips you want to connect are compatible with each other and operate on the same voltage, you are now ready to connect them. but the question is: how to connect led lights together?

there are a couple of ways you can connect the led strip lights. one is good old fashioned soldering and the second is using fancy led strip connectors.

let’s see how to connect led lights using both methods one by one.

weld two strips

Connecting two LED strips by soldering can be very easy or very difficult depending on your skill level. If you are familiar with welding and have the necessary tools/equipment and hands-on experience, we recommend this method.

Before soldering, check the polarity of the copper pads on the led strips. In the case of a simple led strip, you only have two pads: one for positive supply and one for negative supply. make sure to connect the positive of one strip to the positive of the second strip and the same with the negative.

apply a small amount of solder to all copper pads. slightly overlap one strip on the other and weld them. it’s very simple.

If you have an RGB LED strip and want to connect it to another compatible RGB LED strip, you need to be a little more careful. this is because any typical rgb led strip will have four copper pads, in the same area as the two copper pads, as was the case with the single color strip.

then the size of the copper pads becomes slightly small and this makes soldering a bit difficult (but not impossible). as usual you need to align the pads on both led strips. soldering becomes easy if you use the correct soldering tip.

however, the method is the same for single color and rgb led strips: check the compatibility of the strips, align the copper pads correctly (and correctly), and solder them together.

use connectors

now, we will see an easy way to connect led strips using connectors. that’s how it is. you can buy led strip connectors. According to the type of led strip, i.e. single color led strip (with two copper pads) or rgb led strip (with four copper pads), please find the suitable led strip connector.

As far as we know, there are three variants of connectors. the first is a clamp-style connector clip. they simply clip both led strips together and cover them with a flip cover. With this style, the connection between two LED strips will look perfect as if they were a single strip.

For the second type, we have connector clips with pins on both sides and a small wire in the middle. This variant is very useful if you want to make angles with the LED strips or avoid obstacles.

The third variant has a connection clip on only one end of the cable, while the other end is just an exposed cable. this connector is useful at the start (or end) where you want to connect the strip to the power supply.

watch the power supply

We already mentioned voltage in the previous section. another important thing to consider is the wattage of the power supply.

for example, suppose you have a led strip (full 5 meters) that consumes around 24w of power. now if you want to add another full length strip to the first then the total power consumption would be 48w.

so you need to make sure your power supply can provide this power. Assuming 20% ​​headroom, you need a power supply that can provide at least 58W of power. so a safe bet would be a 60w power supply.

Most LED strip manufacturers list the power consumption number on their package or on their website. definitely consider those numbers and use a proper power supply to avoid mishaps.


LED strips can easily increase the aesthetic values ​​of an object/subject. You can use them in cars, computers, homes, offices, to decorate works of art, to illuminate the kitchen and many other places. The benefit of led strips is that you can easily cut them to your desired length and also add additional strips to increase the length. But one important question you may have when connecting the led strips is: how to connect the led lights? In this guide, we looked at a couple of easy ways to connect LED strips.
