As someone who had Lifx due to them not needing a controller, don't buy them their software sucks. It worked fine for months at a time, but would then decide it no longer wanted to obey commands and you'd have to re-pair it, which usually took 30 minutes and 5 failed attempts where it would fail during the setup process after resetting the bulb.
Their bulbs also sometimes just ignored commands, so you'd have to just spam power off or the color you were trying to choose until it finally worked (this was in a room with the bulb and a hard wired wifi AP). The app was also slow and took awhile to start (on flagship Android phone at the time).
Eventually my bulbs died and I haven't gone back to smart lighting yet (though I'm considering ordering some hue or Ikea bulbs).
If you check /r/lifx on Reddit it's basically filled with people complaining about lifx's awful software.
