How to Put LED Lights Behind Your TV

Putting LED lights behind your TV is a great way to spice up the lighting in your living room while also reducing eye strain. It’s a fun project!

At first, installing LED lights behind your TV can seem daunting, but once you understand the basics, it’s a reasonably straightforward process.

In this article, I will break down each step for you. I installed some LED lights on my TV and wanted to share the experience with you.

How to Put LED Lights Behind Your TV

  1. Measure the perimeter of your TV (Multiply the length and width of your TV and multiply by two).
  2. Purchase an LED strip that’s long enough to wrap around all the edges of your display.
  3. Wipe down the rear panel of the TV to remove any dust
  4. Remove the 3M adhesives and fasten the LED strip to the edges of your TV. Use additional two-sided tape if necessary.
  5. For the right angles, either create a loop or curve with the LED strips or use an L-shaped connector.
  6. Plug the LED strip into an outlet and control the colours with the remote or app

It’s up to you to decide how to align the LED light strips on your TV. Most people will choose to run the LED strips around each side of the TV’s panel.

However, if your TV is on a stand, it might be better to only attach LED strips to the sides and top of the TV.

Most LED light strips will allow you to cut sections as needed.

Dealing with 90-Degree Angles

The tricky part of LED light strips is 90-degree angles. Most LED light strips are fairly flexible, but bending them too much can damage them.

If you break one section of the light strip, none of the lights further down the line will work.

You also need to consider the shape of the strip; is it a flat and thin cable or a circular wire shape?

The light strips that use a circular cable are generally easier to install but they’re not as common (and a bit more expensive).

When it comes to installing LED light strips, there are a few different ways to handle 90-degree angles.

Note: Most LED strips include instructions too!

Make a Loop

The easiest way to install LED light strips at a 90-degree angle is to simply create a ribbon loop with the cable.

Most people will opt for this method because it’s the easiest. The downside is that the light can point in uneven directions, which can be noticeable if the strip is particularly bright.

You might also notice the loop sticking out from behind the corners of your TV, which can be distracting when you’re watching movies.

Use an L-Shaped Angle Connector

These are small attachments that create a sharp 90-degree angle that can use for each corner of your display. I recommend buying a solderless snap-down kit. These 4-pin L-shape connectors are a good option.

Make sure to buy a connector that matches the number of pins on your LED strip (2-pin, 4-pin, etc).

You can usually tell how many pins the lights use by looking at the strip and counting the copper points. If the strip supports lots of colours, it will most likely use four pins.

Installing the connector is pretty straightforward. Examine your LED light strips and take note of any cuttable sections. Most strips will have a scissor icon with a dashed border to indicate where to cut.

The sections should also have positive and negative symbols. Match the symbols of the strip to the same pins on the L-shaped connector snap down the clip, and attach the other section of the strip to the other side of the connector.

If you correctly aligned the pins, the LED strip on the other side should work. Repeat the process for all four corners of your TV.

Using L-shaped connectors for your LED lights requires more effort on your part, but it looks much better.

LED Strip Length for TV Sizes

It can be tricky figuring out the LED strip length needed for your TV because each TV has slightly different dimensions.

Your best bet is to measure the perimeter of your TV (or at least the sides you want to install LED light strips on).

Also, keep in mind this doesn’t need to be an exact science because you won’t be installing the LED strips on the exact edges of your display.

The light strip will likely be placed a few inches below each side of the display.

It’s always better to have leftover LED strips than not enough!

32-Inch TV

For a 32-Inch TV, a LED strip that is 92 inches long (233 cm, 2.33 meters) should cover each side of the TV.

43-Inch TV

For a 43-Inch TV, you need an LED strip that is 117 inches in length (297 cm, 2.97 meters) for each side of the display.

55-Inch

To cover each side of a 55-inch TV with LED light strips you need an LED strip that is 149 inches (378 cm, 3.78 meters) in length.

65-Inch

To cover all sides of a 65-inch TV with LED backlight strips you need an LED light strip that is 177 inches (449 cm, 4.49 meters) in length.

Here are some quick recommendations:

Controlling the Lights

Every LED strip will come with its own controller, either a dial, buttons, remote, or an app.

I recommend the LED strips that use an app to control the lights because you can create custom colour themes.

LED Strip Lights Falling Down

If your LED light strips keep falling down, it’s likely because the adhesive was not strong enough. Consider using two-way tape to secure the lights to the frame of your TV.

Why Put Light Strips Behind a TV?

Putting light strips behind a TV improves the ambient light in the room, reduces eye strain, and enhances the visuals on a display. It can be a great mood-setter too. LED lights can also act as night lights for children who are scared of the dark.

The Bottom Line

To summarize, putting LED lights behind a TV is a straightforward process. Most LED light strips are designed to be installed with as few complications as possible. For right angles, either create a loop with the strip or use an L-shaped connector.

Ultimately, it’s up to you to decide how to install the light strips behind your TV. It’s a fun, easy, and safe project that improves the ambient lighting in your home.
