A:Answer The Gradient LightStrip works with any flat screen TV so you don't have to worry about that. As far as Size's Go, That's up to you. The Strip is made to wrap around the Left, Top, and Right side of the TV. You could get a larger one (ex. 65" or 75") to use; but it only comes with 5 Mounts to hold it. (3 Straight & 2 Corner). This would definitely work to provide extra light on the bottom; You would just have to figure out a way to mount the extra length of the Strip.
I have a 65" TV with the 65" Gradient. I didn't like that there was no light on the bottom, so I added 3 Hue Play Bars underneath. I Love It Now.
