Great Option and a reasonable price that doesn’t disappoint

I’m a fan of AI lights but a friend gave me the ZetLights 8300 ufos and they have impressed me with the quality and spectrum. They are quite, clean looking and have an option for a WiFi app control. The settings options remind me of the AI or the Radion but at a lesser price point. Don’t let the price fool you. These lights will do more then most hobbiest will demand. I would like to see more preset factory settings offered to see what other light coloring can be achieved.


Yes to Zetlight!

Great and affordable products that allow me to control it through this app!

Get this game it is so cool ,

Can’t connect to light

I was originally connected to my phone directly but I decided to connect it through my internet when I connected it to the internet through the app I could never see it in the app even though it was on the same network as me anybody got a fix for it ?
