Review: Better than Phillips hue - I upgraded from a 65" lg b6 to a 77" lg B4 and needed new sync lights. At first I was going to get the new Phillips HDMI 2.1 sync box, but it was $389 for just the box and the lights aren't included and cost another $250-300, a bit pricey for what it is. So after some searching around and watching comparison videos on YouTube I settled on these fancyleds sync light/box combo. I only use an nvidia shield so I got the 1in/1out box that came with lights for $259. Unlike Phillips hue where you buy the lights and sync box separately AND on top of that needing the bridge, this set comes with everything you need for a very reasonable price. Now on to performance, it seems quicker to adapt to the colors on screen and the colors it adapts seems more true to what's on screen. The lights are brighter and more dense than my previous hue lights, and they are long enough to go across the bottom of the TV, not something the hue lights do. During high speed action scenes there's zero lag between what's on screen and the sync lights. The first photo is from an anime called fate stay, I haven't actually watched it but it came up when searching "best hype and aura moments in anime", it's the fight between saber alter vs rider and is a great video to demonstrate sync lights as it's high quality, fast paced, and flashy giving the sync box and lights a real work out. Installation was simple, stick the lights on to the TV, connect everything through the sync box, and then download the app. I haven't dug into the app yet and it still functions perfectly so you can decide on how involved you want to be with the whole set up. Even if I can't comment on how it matches up with the govee sync box I can honestly say fancyleds blows hue out of the water, no contest.
Review: Best in the game no camera's - absolutely love my Fancyleds 2.1 Sync Box. It has completely transformed my living room into an immersive home theater. The way the LED backlighting syncs perfectly with whatever is on the screen truly makes watching TV come to life. The colors are vibrant, the responsiveness is instantaneous, and the HDMI 2.1 support ensures that I get the best possible picture quality without any lag. I highly recommend this to anyone looking to upgrade their entertainment setup!

### ⭐⭐⭐⭐⭐ Absolutely loving this!
*by J***N on November 30, 2025*

What sets this apart is that it uses the feed directly from the receiver—no bulky camera stuck to the top of the TV like other brands. Setup was super easy, and my whole family is obsessed with how much bigger and more immersive it makes the TV feel. I previously had a similar model from another company, and it was just okay. This one, though, looks fantastic—clean, bright, and way more accurate with the colors. The clip I shared is from one of the best scenes in Game of Thrones (Battle of the Blackwater), and this was filmed at 2 PM with the lights on. It looks even brighter and more incredible in a dark room. If you're on the fence, this is the one to get.
