Our take on the Power Practical LED Lights for TV Backlight - Luminoodle

The Luminoodle is a USB-powered LED strip that mounts behind a TV to add bias lighting. It runs off the TV's own USB port, so it switches on and off with the set, and the 118-inch strip is long enough to loop around large screens. True white light only, with no color or app control, which keeps it simple but limits it against RGB rivals. Buyers use it to ease eye strain in dark rooms and add contrast to the picture.
