I bought 4 color ambiance bulbs for my ceiling light and 2 lamps 2 years ago and they still work great. I expanded my scene with 2 hue go’s and 1 gradient light-strip that attached to my desk. The scenes are amazing and dynamic. I have a dimmer switch made by another company that are “friends of hue.” It’s great because the switch fits on top of my light switch and I can turn on my lights with a button and adjust the brightness. I can also use my voice to change colors or get my lights to sync to my music using Spotify. My bedroom is my haven and these lights make any mood I want to set. Best purchase. My walls are white for the best effects. I purposely bought a white desk so the colors would bounce off of it better.
