That starter kit has been on sale for a minute.
Yes. The white bulb kit is cheaper.
I've been thinking about getting google home and one of the multicolor kits but I'm not sure that I'll find it all that useful.
Idk much about Google Home yet but I can honestly tell you that with having 4 Echo Dots around the house, GE Link bulbs in almost every room, and motion sensors that control the lights, it's already sick so that Phillips Hue with colored bulbs would be crazy. If you have any artwork or whatever on you walls you would be able to highlight them in different colors, have your bathroom different colors at different times of day or change it based on your mood, etc, all with motion and/or your voice.
I don't recommend too many things to people but I'm telling you, go for it.
Edit: I think ima grab this light strip too and plug it into a smart socket. IFTTT it into the smart home setup
