Our take on the Soifcik 18ft TV LED Backlight with Screen Sync Sensor
The Soifcik 18ft TV LED Backlight is a stick-on LED strip with a screen sync sensor that reads the colors on your TV and matches the glow behind it. It is sized for 75-85 inch TVs and adds 24 scene modes plus 6 music-sync effects through the uLamp app. It suits people building a dark-room home theater or gaming setup who want bias lighting without a hub. Against rivals, the screen-sync sensor and music modes are the draw; the trade-offs are app dependence and a strip that only shows well in a dim room.

- Yes. The 18 ft strip is sized for 75-85 inch TVs, and the 12 fixed buckles help route it around the back edges.
- Does it work without the app?
- Basic lighting works from the included adapter and sensor, but scene modes and music sync run through the uLamp app.
- How does the screen sync work?
- A sensor sits at the top center of the TV and reads the screen colors, and the strip changes to match them.

- The LED strip, the sensor, a power adapter, a quick guide and 12 fixed buckles.
- Can I use it on a monitor or smaller TV?
