FFJ TV Backlight 14.7ft cuttable LED strip with sensor, app control and TV colour sync (55–65 inch)
Product description
If you like your TV setup to feel a bit more “live”, this FFJ TV Backlight is aimed at that exact mood. It uses a sensor to detect colours from the screen and then lights the LED strip behind the TV so the ambient glow changes with what’s on-screen. It’s a simple idea, and in the right room it can genuinely make gaming, films and music sessions feel more immersive.
That said, it’s still an add-on: results depend quite a lot on how your TV is positioned, how bright the room is, and how carefully the strip is placed along the back edge.
At a glance
This is a cuttable, 14.7ft TV LED backlight kit designed for TVs between 55 and 65 inches. It’s built for easy setup: you attach the sensor to the top centre of your television and connect the light strip to the rear of the TV.
On the smart side, the lighting can be controlled via a mobile app (uLamp is mentioned) and there are multiple lighting modes. The backlight also includes automatic on/off detection, which removes some of the hassle of managing the lights manually.
What stands out in use
The core feature is the “TV sync” effect. The sensor is designed to capture the colours being displayed and then reflect those changes in the LED lighting without a noticeable delay. In practice, you’re mostly going to notice it during scenes with strong colour shifts—think games with lots of neon UI, darker film scenes with bright highlights, or music videos with rapidly changing colour grades.
A small but useful limitation: because it relies on what the sensor sees, bright rooms can reduce the visibility of the backlight effect. FFJ also specifically suggests using it in a darker environment for the best retroiluminated look.
And because the strip is described as cuttable, you’re not forced into a one-size placement. That can help if your TV stand setup or wall position means you want to trim and route the strip more neatly.
Key features
There are a few layers here beyond just colour sync:
- App control for scenes and colour adjustments through the uLamp app.
- Multiple ambience options, including 24 dynamic light scenes.
- Music-related sync effects, with 6 effects mentioned for syncing to music.
- Adjustable brightness and colour saturation are referenced, so you can dial in a softer look for casual viewing.
- Long longevity rating of up to 50,000 hours is provided, which is a sensible thing to look at if you plan to leave the lights on regularly.
If you’re the type to switch between “watching” and “having a vibe”, these modes matter—especially for music and gaming nights when you don’t always want strict screen mirroring.

Who it’s for (and who should skip it)
This is a good fit if you want an easy, visual upgrade for a home cinema feel—particularly for 55–65 inch TVs where you can run the strip along the back edge cleanly, and you’re happy to use it in a dimmer room so the effect is clearly visible.
It may not suit you if your main goal is subtle lighting in a bright living room, or if you’re after something that feels fully “professional-grade” in response quality and placement tolerance. Screen-sync products tend to be sensitive to setup, and if your TV environment is constantly changing (strong daylight, glare, lots of reflections), the effect can look less dramatic than the concept suggests.
Final verdict
Worth buying if you’re looking for TV backlighting with colour-changing sync, app control, and built-in ambience modes, and your space is dark enough to actually see the glow.
Better avoided if you mainly watch with strong ambient light, you’re not willing to mount the sensor correctly, or you don’t want to spend a little time getting the strip placement right.
A sensible approach is to treat this as a mid-range home upgrade: it’s designed to deliver fun, immersive atmosphere more than “cinema studio accuracy”. If that matches your expectations, it’s the kind of kit you’ll likely keep using.
