The Merkury Innovations Sound Reactive TV Backlight is a corded RGB LED strip that mounts behind a TV or monitor and reacts to sound. It offers 8 colors, four lighting modes (fade, strobe, smooth, flash) and a remote for brightness and color changes. It suits budget buyers who want ambient bias lighting and a party-style sound mode without smart-home features. Rivals in this class often add app control, music-sync microphones with better tuning, or addressable multi-zone effects; this one keeps to a single strip, a remote and basic sound reactivity. Its 3.7 rating from 275 buyers suggests it works for many but leaves a share of owners unimpressed.

Buyers rate it around 3.7 out of 5. Many like the color options and the sound-reactive effect for the money, while others report weak or unreliable sound sync and mounting that does not hold.
