Review: I’ve been using this LED backlight for my 55-inch TV and so far it’s been a great buy. The strip quality feels solid, and the adhesive gum is strong enough to hold well around the edges without peeling off, which was something I was concerned about. The lights themselves give a nice atmosphere when watching movies or gaming, and the app control with music sync makes it even more fun. The color transitions are smooth overall, though I did notice that sometimes the shades don’t perfectly match what’s on the screen. It’s not a dealbreaker, though - it still looks really good behind my TV and adds the effect I was hoping for. Overall, I’m happy with the purchase. The setup was simple, the adhesive gum is reliable, and the backlight definitely upgrades the TV experience.
Review: I'm delighted with the LED backlight for FFJ TV. The installation was very simple and the result exceeded my expectations.

In addition, the smart control allows you to easily change the modes and brightness from the phone or remote control. The LED strip is cuttable and flexible, so it adapts seamlessly to the size of the TV or monitor. The quality of the adhesive is also excellent, it stays firm without peeling off. 💡 In summary: a perfect purchase to improve the visual experience and give a modern touch to any room.

*by R***L on 7 November 2025*

My husband installed this on our TV and I love it, the only reason why this isn’t a 5 star product is because the color variation could be better. Other than that it works really well and adds a fun vibe to movie watching. The adhesive has held up for a few months now so I think it’s safe to say the quality is good.
