TV Backlights, 13.1FT LED Lights for 32-65 Inch TV, RGB TV
$0.61
Product Overview
The KANTUTOE RGB TV LED Lights transform your viewing experience by adding dynamic, responsive lighting behind your screen. Designed for TVs ranging from 32 to 65 inches, these USB-powered backlights sync with on-screen content and audio to create a vibrant, immersive atmosphere. Whether you’re watching a movie, playing video games, or enjoying background music, the lights pulse and shift in real time, enhancing both visuals and ambiance. With support for both a handheld remote and a Bluetooth mobile app—“Lofur Lanfern”—you have full control over color, brightness, and effects, making it easy to customize your space without complex setup.
Unlike static backlighting, this system responds dynamically to what’s happening on your screen. Action sequences trigger bold reds and whites, while calm scenes soften into blues and greens. The built-in music mode amplifies sound-reactive effects, so every beat or bassline brings the strip to life. Ideal for bedrooms, gaming rooms, or home theaters, these LED strips turn passive screen time into an engaging sensory experience. Since they’re USB-powered, no extra wall adapter is needed—just plug them into any standard USB port on your TV, computer, or power bank.
Key Features
- Music Sync & Audio Response: The LED strip detects audio from your device or environment and changes colors in rhythm with the music or on-screen sound. This creates a lively, synchronized visual effect that deepens immersion during gameplay, film scenes, or ambient listening sessions.
- Bluetooth Mobile App Control via “Lofur Lanfern”: Connect your smartphone or tablet using Bluetooth to access advanced features like custom color palettes, timing effects, and scheduling. Simply download the app by scanning the QR code on the product packaging or search “Lofur Lanfern” in the Google Play Store or Apple App Store. No internet connection is required once paired.
- Handheld Remote Included: Operate the lights instantly without pulling out your phone. The infrared remote offers quick access to preset modes (such as flash, strobe, fade), brightness levels, and color selection, ensuring seamless control even when lying down or away from your device.
- USB-Powered Convenience: Eliminates the need for an external power adapter. Just connect the included USB cable to any available USB port—on modern smart TVs, laptops, monitors, or portable chargers—for reliable operation. Energy-efficient design also means lower electricity usage.
- Vivid Full-Spectrum RGB Lighting: Offers over 16 million color combinations across red, green, blue, and blended tones. Colors shift smoothly based on content or user preferences, creating depth and drama behind your display.
- Flexible 13.1-Foot Strip for Full Coverage: At nearly 4 meters long, the adhesive-backed strip can fully wrap around larger TVs up to 65 inches wide, ensuring even illumination along all edges. Its flexible construction allows easy shaping around corners or irregular surfaces.

Benefits & Use Cases
This lighting solution is perfect for anyone who wants to elevate their entertainment space without professional installation or complicated wiring. Gamers will appreciate how the lights react to fast-paced action—flashy explosions trigger bright flashes, while stealth scenes dim to subtle purples and grays. Movie lovers enjoy deeper cinematic immersion, as warm tones enhance dramatic lighting in films, and vibrant hues pop during sci-fi or animated content.
In bedrooms, the ability to sync with music or set mood-based scenes turns your room into a personal lounge. Use the app to program sunrise simulations or calming gradients before bed. Since it’s USB-powered, it works reliably with laptops, monitors, and most smart TVs that include USB ports—no additional outlets required. The compact remote ensures you never miss a moment of control, whether you’re on the couch or still in bed.
Installation is straightforward: clean the area behind your TV, peel the adhesive strip, and press firmly into place. Avoid covering ventilation slots or placing near heat sources. Once connected, pair via Bluetooth using the “Lofur Lanfern” app for maximum customization. With its balance of ease, functionality, and visual impact, this LED strip delivers significant value for casual users and tech enthusiasts alike.
Important Notes
Ensure your TV falls within the 32–65-inch size range for optimal fit and coverage. Larger screens may require overlapping segments, while smaller ones might leave gaps at the top or bottom—plan placement accordingly during installation. Always clean the surface thoroughly before applying to ensure strong adhesion; dust or oils reduce stickiness.
Direct line-of-sight between the remote and light strip is necessary for infrared signals to register properly. Obstructions like thick curtains or furniture can interfere with remote functionality. Download only the official “Lofur Lanfern” app from trusted app stores to avoid security risks or incompatible versions.
The included package typically contains the 13.1-foot LED strip, micro-USB cable, remote control, and printed instructions. Verify all components upon delivery. While durable under normal use, avoid repeatedly bending the strip beyond its flexibility limits or exposing it to excessive moisture, especially near vent areas.

Exactly what I wanted , fits TV as expected
I can’t think of anything bad to say about this light strip. There are plenty of brightness settings, lots of color choices and the lights power on and off when I turn my TV on and Off so I don’t have to use the separate remote. With the 16.4 length option I had more than enough to cover the outer edge of my 65″ TV. Since I am essentially using them for BIAS lighting I can’t say I notice any flicker at all as I’m never looking directly at the light source.Installation is easy if you are familiar with the process. The adhesion is good, making 45 degree corners can be a little tricky if you’ve never used this type of light strip before , I highly recommend you get an idea of how you want to lay out the lighting before you start pulling back the tape that covers the adhesive, and then when you start sticking it on just pull the tape back as you go. That or get some plastic led strip clips and don’t even pull off the tape or deal with the adhesive.I’ve had issues with other USB light strips not being able to reach their full brightness due to power limitations on the TV, but I can crank this one all the way up with no problem.I use my TV in a very dark space, and I find that for me personally the default blue setting at about 50% power really helps reduce eye strain without being a distraction. That said there is a lot of color customizing you can do if you’re looking for a very specific color.The only thing worth mentioning is that whole these types of lights have a setting for White light, they really don’t produce anything close to a natural white like from a light bulb, they also don’t have any setting that looks like a true warm ambient light. That is no an issue with this product specifically, but with all similar light strip. So if you’re looking for white , soft white, or a warm light look you need to look at a completely different type of product.The attached pictures show the lowest and highest brightness as well as how the strip fits the back of the TV.

I am absolutely blown away by the KANTUTOE TV Backlights! I recently installed them behind my 50-inch TV, and the difference is stunning. The RGB LED lights create an immersive ambiance that enhances my gaming and movie-watching experiences. The music sync feature is also incredibly cool, as the lights pulse and change color in time with the audio.The installation process was surprisingly easy, and the adhesive strips held the lights firmly in place. The Bluetooth app and remote control make it simple to adjust the colors, brightness, and effects to my liking.Overall, I’m thoroughly impressed with the KANTUTOE TV Backlights, and I’d highly recommend them to anyone looking to elevate their home entertainment setup. The quality, features, and value are all top-notch!

Backlights
Easy to apply, nice and bright, good color. The only thing I donât care for is that the lights donât turn on or off when turning the tv on/off. I have to use the remote every time.

Great lights. Nice ambience!
I got my 11 year old son this for Christmas. He loves it. It was easy to stick on the back of the tv. The length was perfect for the 44 inch tv. The light gives a nice ambiance. Not too bright and the remote is cool. My son loves all the different colors it can change.

Works great
Works great fits our 58 inch tv perfectly and then some. The remote does clash with other neon display things but it works great with the lights and all the colors work. Highly recommend

They work but…
First and foremost, these lights seem to work just fine. For me, the quality I was hoping for wasn’t there but for how affordable they are, I could forgo that. The adhesive on them seems pretty sticky and they seem to stay in place on the back of my TV despite there being a texture. What I didn’t care for was the backing for the adhesive being split between two pieces that were adhered to the LED strip – I had to pull back some of the adhesive that laid over the top of the backing of the next adhesive strip in order to pull the backing off the next piece. Next, I found it pretty difficult to round corners when I was applying it. The corners look terrible on the back of my TV…nobody will typically see that depending how you have your room and TV set up. That leads me to my next concern – these strips are white and most TVs are black. If your TV is placed like mine where you could get a small glimpse of the back, the white strips might stand out to you… that’s just something to be aware of. To use these effectively, your TV should be up against a wall. Next, I found these need a USB port to plug into on the back of your TV so be aware you’ll one available for these. I found the remote to be a bit touchy. It seems to need to be angled JUST right to actually connect to the lights. A big bonus is that there is an app you can use to control the lights instead. I find that way easier to use than the remote. Overall, I find the lights are a bit harsh when flashing between colors. There doesn’t seem to be a way to set the lights so they gently go to and from the next color. It seems to have a strong, strobe-like effect so be aware!Overall, I would say these are a budget friendly option. They just aren’t what I was hoping for in the quality department.

We have a pack of these on every TV in our house, but they do look especially good on my smaller TV in my bedroom (see picture.) Theyâre a decent price for a good strip of LEDâs, a remote for colour changing/effects and a charger. The glue on the back of the strips are pretty solid, I had one strip once randomly fall off the back of the TV causing a rip in the strip so had to buy another pack, but it was most likely due to the heat/condensation and that my wife had dusted around the back of the TV prior to it happening.If you have extra after wrapping around the back, donât cut it! Wrap it around a second time as much as possible or try to get it to one side to the other with the extra. It provides some nice extra glow, and you can always dim them on the remote if you regret it. The remote also has some cool functions, one of them listens to the sound of whatever electronic you have in on and changes colour to the audio, it probably would be great for house parties! 10/10
