Probably the best available for the money
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
I love these lights. High-quality dynamic backlighting for your TV. With the calibration and settings dialed correctly, it moves and breathes smoothly with the picture as you use the screen. With this installed it really amps up the cozy and artsy vibes of the screen, adding further immersion. It's also easier on your eyes in a dark room to add backlighting. You can set the brightness level to the level you want, and you can fully control the colors and tone, whether you want to set it to something static, add a colored border, or use the dynamic lighting (which is what I'm currently using). These lights were made for 55 inch to 65 inch TVs. There are four strips rolled up, two for the short side and two for the long side. No matter which corner you start from, you will be able to set it up properly during calibration. The strips stuck well so far but were not so firm that I couldn't pull up one strip to reapply it. The TV I have here in the pictures is the Sony Bravia ii OLED 4K panel (~$2000 screen, excellent picture quality for the price point). I am using a Rocketfish omnidirectional wall mount behind it. TIPS I followed some other reviews here for the calibration. It was recommended to set the TV brightness to max for calibration, then adjust both TV and backlight brightness after setup. The physical setup only required me to have a TV pulled forward from the wall a foot or so, plus a 3-step ladder so I could easily reach the top of the TV. You could absolutely install this on a TV sitting a bit forward on a stand as well. App setup was a breeze once the lights and camera were attached properly. I will sort out my cable management eventually, once I have a TV shelf installed below my panel which is my next goal for this room. The kit comes with some additional adhesive to secure the lights that I didn't end up using, as the adhesive on the back of the light strips was sufficient for now. I'm saving the extra parts just in case. Overall I highly recommend it! The dynamic lighting adds so much immersion without being loud or flashy unless you want it to be. Kinda just blends into the background and subtly amps up the quality of your whole experience. Like the color on the picture just blends seamlessly into the wall and the room.

Best lights out there
Size: 11.8FT for 55''-65'' TV
absolutely love it makes the colors stand out just so much more makes movies so much more immersing and the sound reaction makes you feel like your almost inside the movie if you have dolby atmos speakers (8d) and the app is so simple and easy all their products including this are just efficient and useful and one of my favorite parts about the app is the upload center you can use other people’s led light settings if they publish it and definitely the video capturing the camera does not have a adhesive by the way but it is definitely stable the led lights adhesive is very good re taped it after the first time because it was a little croooked and the adhesive was still really good i haven’t had any issues in the past 2 ish months the app is very smart the timer works just on point the brightness is amazing if it doesn’t feel like it just wait till the room is pitch black and lastly the apps control is great so simple and effective just not doing too much you know

An effective TV watching enhancement
Size: 7.8FT for 40''-50'' TV
The Govee TV Backlight 3 Lite transformed my TV-watching experience. Installation was quick, the adhesive holds well, and the calibration process is a little tricky and will take time to get right, from mapping out the TV size to setting the light quality up within the app. But the light quality is good and works best in rooms which are very dark with no external light sources to influence the color the camera picks up. The ambient lighting makes movies and gaming feel more immersive without being distracting. The app controls are intuitive, and the customization options let you fine‑tune everything from brightness to color modes. If you want an easy, affordable way to elevate your TV experience, this backlight delivers as promised.

One of my favorite purchases ever.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
So I bought this backlight a few months ago and it's been one of my favorite purchases I ever made on Amazon. Honestly, once you start using the backlight, it's so hard to go back. It makes TV and games just so much more immersive, especially when there are bright scenes and the lights flash, or when there are dark scenes and it just goes completely black. The setup is really easy but it does take some precision to get it right the first time and to keep it working for a long time. And sometimes the things that stick the wires to the back of the TV do like to fall off. Although that may be a consequence of how my TV is built. I think it looks best in a darker room where there's less space for the light to go away, especially when the TV is against a wall. But that's how I use it, and it's been just an amazing experience. The app functionality is also pretty good, although I don't use it as much these days and I just keep it in TV syncing mode. The lights can get really bright, so if you want to, you can use it as a separate ambient lighting for your room. Although personally, I think that's too much effort and I just use my lamp. Coming from someone who uses his TV a lot, if you're on the fence, just get it

Movie lighting must have.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
This is exactly what it was in the listing. It was very easy to install they stick to the back of the tv very well. The lights strip is good quality and they wont fall off the tv even from the heat.. The app is easy to use. Will say there are a lot of options to control it from the app. Once the control box is behind the tv your not going to be reaching back there to turn it off and on. I have mine connected to Alexa and Google so i can control them with my voice. They look great for watching movies even in a somewhat lit room. Be mindful of the camera on the top of the tv I did have to calibrate it 7 times cause it wasn't picking up all the corners and i accidentally hit the camera while walking around if your tv is on the wall you have nothing to worry about unless you have my first issue of it not catching the corners properly. The little orange squares don't stick too well especially since i had to do this several times. Even tried it without the squares and still had problems. The video was recorded after the second time of calibrating it. The problem comes when you try to get the hue right. Everything white makes the lights turn red so i had to mess with the saturation and the white balance on color calibration feature on the app to get it as close as possible to the white on the tv and its still something i have to adjust ever time i watch something.(Shown in the second picture)
