LED Strip Lights For TV
10 productsPutting LED strip lights behind a TV does more than just look cool. The right TV backlight kit reduces eye strain by softening the contrast between a bright screen and a dark room, making movies and games more comfortable to watch. These TV LED lights typically come in shorter lengths perfect for 45" to 75" screens and run on safe, low-voltage 5V DC power, letting you plug them directly into your TV's USB port.
We stock two main types of LED for TV applications. The first is a simple, static color backlight that provides what's called 'bias lighting'. You set it to a single color (like neutral white) or have it slowly fade between colors. The second is a dynamic, addressable LED system that actively syncs with the image on your screen. These kits use an HDMI sync box or computer software to read the video signal and reproduce the on-screen colors on the wall behind the TV, creating a massively immersive viewing experience.

How to Install LED Strip Lights Behind a TV
Installing a TV light strip is a quick job, but a few details make all the difference. First, measure the perimeter of your TV where you plan to stick the strip—usually about 2-4 inches in from the edge. Choose a kit that matches this length. Before peeling the backing, wipe the surface with an isopropyl alcohol pad to remove any dust or oils; this is the number one reason for adhesive failure. Most of our kits use pre-applied 3M adhesive that holds strong, even with the heat from the TV.
When you get to a corner, don't try to make a sharp 90-degree crease, as this can damage the circuit. Instead, you can either use a solderless corner connector or gently loop the flexible strip back on itself. For power, most TVs have a 5V 1A USB port that works perfectly. If your lights flicker or won't turn on, the port may be underpowered (0.5A), and you'll need to use a standard USB wall adapter instead, like one you'd use for a phone.
Smart Control Options for Your TV Backlight
The simplest TV led strips are controlled by a small infrared (IR) remote. But many of our kits offer much more advanced control. Look for our Wi-Fi enabled kits that connect to the Tuya or Smart Life app on your phone. This lets you access millions of colors, set schedules, and create custom scenes. Many of these kits also integrate with Amazon Alexa and Google Assistant, so you can turn your television lights on or off with a simple voice command.
Frequently Asked Questions About LED Strip Lights For TV
Got questions before you buy? I've been answering them for 12 years. Here are the most common ones I hear about TV backlighting.
TV backlighting is just placing a light source, usually an LED strip, on the back of your television. The light bounces off the wall behind it, creating a soft glow. This is often called 'bias lighting.' It's not just for looks; it reduces eye strain by softening the contrast between a bright screen and a dark room, making for more comfortable viewing.
The best TV light strip depends on what you want it to do. If you just want a static color or simple white, a basic USB-powered RGB kit is fine. If you want the lights to react and change color with what's on the screen for movies and gaming, you need a 'dream color' or screen-sync kit that uses an HDMI sync box or PC software like AmbiBox.
For the best glow and most even light, stick the LED strip lights about 2 to 3 inches in from the edge of the TV. Make sure the LEDs are facing away from the television, out towards the wall. This placement gives the light enough space to spread out and create a soft, diffuse halo instead of a harsh, narrow line.
It's a valid concern. Any device that sits in your HDMI signal chain can technically add a few milliseconds of latency. With high-quality HDMI sync boxes, it's almost always imperceptible for watching movies or casual gaming. For competitive, high-framerate gaming, some pro players might notice it. A software-based system like AmbiBox on a PC will have the least input lag.
Yes, for most basic kits, that's normal. They are powered independently. Some TVs do cut power to the USB port when turned off, which will shut off the strip, but many don't. If you want them to sync with your TV's power, look for a smart kit like our Wi-Fi Alexa kit, which you can control with your voice or integrate into a smart home routine.
Absolutely. While they're sold as TV lights, they're really just short, easy-to-use LED strip kits. They're perfect for backlighting computer monitors, lighting up the area behind a desk, inside a PC case, or tucked behind a headboard. Since many are USB-powered, they're quite versatile for smaller projects. We have a whole category of USB powered LED strips for these kinds of jobs.
Yes, they work great. The flexible PCB of the LED strip will easily follow the contour of a curved TV. The installation process is exactly the same. Just be sure to press the strip down firmly along the back of the TV to make sure the adhesive makes good contact all the way along the curve.
We do that all day. A huge portion of what we ship is built to a customer's drawing. Just send us the height and width of your TV. An engineer will spec out a kit with the strips cut to the perfect length and pre-soldered with flexible corner wires. We'll send back a complete parts list, wiring diagram, and a price, usually the same business day and always within 12 hours. There's no fee for the consultation and no obligation to order.
