  • Works amazing
Color: Multicolor Size: 14.7FT for 55''-65'' TV
The media could not be loaded. I recently purchased the FFJ TV LED Backlight, and it has been a fantastic addition to my home entertainment setup. The installation was straightforward, with clear instructions and strong adhesive backing that holds securely to the TV. The light quality is impressive, offering vibrant colors and adjustable brightness that significantly enhances the viewing experience, especially during movie nights. The color synchronization feature works seamlessly, creating an immersive atmosphere that makes the visuals pop. What I also appreciate is the variety of modes and customization options available through the remote or app. Whether you want a relaxing ambient glow or a dynamic light show synced to music, this backlight delivers. Overall, the FFJ TV LED Backlight is a great value for its price. It’s a simple upgrade that transforms your TV experience. Highly recommend it to anyone looking to enhance their setup! ... show more

  • Easy set up!
Color: Multicolor Size: 14.7FT for 55''-65'' TV
Amazing product that really makes a difference in your viewing experience. To walk you through the set up it was very easy to put together behind my 55 inch tv. The sticky material/adhesive was strong to stay against the tv but also strong enough to be remove and replace positions. Had to move it around due to the back of my tv design. Once set up the app was a simple download from the App Store and connect to the tv light instantly. It’s been great for watching movies making it so colorful and vibrant. Great value for your money and would recommend to others. ... show more

  • These TV lights are a game-changer – so cool and so easy!
Color: Multicolor Size: 14.7FT for 55''-65'' TV
The media could not be loaded. Okay, I’ve gotta say, these lights are way better than I expected. I can’t understand why this product has so many negative reviews (I’m the kind of person who checks reviews first, but I still went for it - and I’m glad I did.) First off, the light strip is really great quality- sturdy and well-made. You know when something feels cheap? Yeah, not these. They actually feel super fancy, and I was honestly surprised! Let’s talk about installation - because I hate complicated setups, but this? So easy! All I had to do was clip the little sensor to the top of my TV, stick the light strip around the back, and plug it in (oh, and no, I didn’t even use the provided clips, the adhesive is strong enough to hold the strip just fine on its own.). That’s it! No tools, no stress, just done in minutes. Even if you’re bad at tech stuff, you’ll get this right. Now for the fun part: the lights themselves. WOW. They match the colors on the screen instantly, and it’s so smooth. I watched a movie, and it felt like the action was spilling out of the TV into the room. Playing video games? Whole new vibe. The colors are super bright and vivid, but you can adjust everything if you want it softer. The app makes it easy to customize (also was very surprised about the app rating - mostly negative for some reason, but in reality it’s very simple and works perfectly fine, connected to a strip within a second). Oh, and the modes - SO many cool modes! You can pick from holiday scenes, moods, and even music sync. I played some of my favorite songs, and the lights danced to the beat. My living room turned into a mini concert! I even caught my dog staring at the lights, totally mesmerized lol. One thing I noticed: these lights are best in the dark. I tried them with the room lights on, and while it’s still cool, in the dark, it’s a total showstopper. It’s like being in a private theater. If you love movies, gaming, or just want to make your living room way cooler, you are at the right place. They’re easy, fun, and honestly make TV time way more exciting. I can’t believe I waited this long to try them! Will say it again - if you want the whole setup to work perfectly, make sure to adjust the main sensor properly. It’s super important! If you don’t, the colors won’t match your TV screen perfectly. Honestly, that was the longest part of my installation (took me like 5 extra minutes of moving it up and down to get it just right). Hope someone will find my review helpful. ... show more

  • Transform Your TV into a Cinematic Masterpiece with This Incredible LED Backlight Kit!
Color: Multicolor Size: 14.7FT for 55''-65'' TV
This TV backlight kit has completely exceeded my expectations! From the moment I opened the box, I could see the attention to detail and premium quality of the product. The LED strip’s vibrant RGB colors and sleek design make it the perfect addition to elevate any home theater setup. The lights are easy to install, and the flexibility of the strip allows it to fit perfectly on my 55-inch TV. The synchronization with the app is seamless, and the variety of lighting modes makes it incredibly versatile for creating different moods. The app control is intuitive, providing a range of customization options that make the experience even more enjoyable. One of the most surprising and delightful aspects was how well-packaged the product was, complete with extra mounting clips and even a cleaning pad to prep the surface. The inclusion of everything needed for a flawless setup shows the thoughtfulness of the manufacturer. This backlight not only enhances the TV viewing experience with immersive lighting but also adds a touch of sophistication to the room. Whether you’re watching a movie, gaming, or just relaxing, this product transforms the ambiance entirely.
