This is an excellent addition to a TV backlight. If you go into the GOVEE app you can sync this device to a TV backlight with a camera. You can add up to five lights. I recommend this for either a TV backlight or general ambience in the room at night. UPDATE 2025: I actually have 4 of these. 3 of them I synced with the TV strip light/camera using the GOVEE app for TV watching. The 4th one I use is on ambience lamp. These are made very durable/easy to set up. These things are not cheaply made I highly recommend

Look nice and were an easy setup.

Simple and do what they are supposed to do. I use them to add a bit of flare to my desktop setup for online meetings, etc. If I had to nitpick, I'd say cabling is always interesting to route to reduce desk clutter, but I am not going to remove a star for what pretty much has to be. They look nice too.

Good, but missing white (ww) hues hurt performance

I bought these lights just a little over a year ago, and overall I’m pleased with them. I bought them because standard strip lighting does not work well with the shape of my ultra flat TV, something I did not consider on purchasing the TV. The lighting effects that these can produce are really impressive, at times you can see what appears to be the individual LEDs and the effects are somewhat more granular or pixelated than other lights from GOVEE. The issue I have with these lights is that they are not able to produce cool, white and warm white, and they do not render colors like other bulbs from GOVEE. Colors on these lights tend to be brighter than every other light source I have from Govee, including their lightbulbs and their floor lamps. Although I knew about the white rendering, I did not realize how annoying it would be to see warm, white and cool, white rendered poorly on these TV lights. If you want to truly seamless and integrated looking product, I suggest you look elsewhere as these aren’t quite there. If you don’t care or are using these in a room where you don’t have any other light sources from Govee, then go for it — you’ll love them.

Great way to control TV and radio in one room from an easy chair in another room!

I help a 96 year old blinded vet with tech support -- and as his health worsens, needed to make his TV, his radio, and the audio switch that selects what audio should go into his hearing aids via Bluetooth work from his easy chair in his living room. All the equipment is in his bedroom. This IR repeater system installed quickly and easily and works perfectly. Now he can summon ball games, news, or whatever he wants without fear of getting up and falling down. A perfect solution!
