  • Our take on the TV LED Backlight, 23ft LED Lights for 70-100 Inch TVs

    The KANTUTOE TV LED Backlight is a 23-foot RGB LED strip designed to mount behind TVs from 70 to 100 inches. It has a built-in microphone that syncs the lights to music and sound, 20+ dynamic modes, 16 million colors, and dimming to reduce eye strain. It suits people who want ambient bias lighting for a large TV or monitor and who value sound-reactive effects over smart-home integration. Compared with rivals, it offers a long strip and music sync at a budget level, but lacks app control and Wi-Fi, and the adhesive may need extra clips on some surfaces.

    About the TV LED Backlight, 23ft LED Lights for 70-100 Inch TVs

    This is a 23 ft RGB LED backlight strip for 70 to 100 inch TVs. It sets ambient light behind the TV and can also be used on a computer monitor or in a kitchen, living room or bedroom. It offers over 20 dynamic modes and 16 million color variations.

    A built-in high-sensitivity microphone picks up music and ambient sound in real time. When you press the music button on the remote, the colors and speed change with the sound. The lights are dimmable, so you can raise the light level around the TV in a dark room to reduce eye fatigue from the contrast in brightness.

    The strip is long enough to run along every side of the TV. Foam adhesive and clips hold it in place. The mini receiver can be hidden behind the TV.
