Review: Fancy lights - Thank you . Love these lights
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.

### ⭐⭐⭐⭐ 1,5 Jahre Benutzung und immer noch gut!
*by D***N on 1 April 2026*

Die LED Box haben wir an unserem LG B1 77 Zoll verbaut. Weiterhin ist die Box in der HDMI Schleife zwischen TV und AV Receiver. Technisch funktioniert das erstaunlicherweise mit allen HDMI 2.1 Features. Die LED samt dem ambilight Effekt sind gut - sehr gut, bei Funken Szenen flackert es manchmal, was mit der Speed Einstellung in der App auf 1% nahezu ausgemerzt ist. Die Helligkeit haben wir auf 55%, damit es sanft und angenehm hell wirkt, ohne zu betont zu sein. Die Farben sind stark, Abstufungen erkennt die Box gut. In manchen Szenen hat er problem mit gelb bzw. grün, beides zu unterscheiden. Insgesamt nach so langer Zeit hinterlasst es aber einen tollen Eindruck.
