I’ve had an unacceptably high AFR with all LIFX bulbs, although I’ll concede their support is fantastic at shipping replacements to me. We’ve had about 20-22% failure rate of bulbs within 2 years of ownership, seen across ~60 of them. In addition to that about another 20% have needed factory resetting once or twice in the same period, because they stopped interacting with WiFi and the first-party application in ways that just turning off and on again at the light switch didn’t fix.
In contrast to this we’ve had exactly one Philips Hue fail on us. Also cheerfully replaced for us. None of them have needed resetting and we have about the same # of light fixtures deployed. Probably the most annoying problem is Hue Play’s are prone to coil whine at 100% brightness on on certain scene colors, particularly those involving blue-white (6000K). Resolvable by going < 5000K or dropping to 90% brightness, I haven’t attempted to get warranty replacement for this issue but about 16/22 of my Hue Play’s are affected by the issue.
Integrated with Google Home it’s also common that some % of LIFX bulbs won’t respond to a “turn off all the lights” command, whereas Philips is very good at on/off even when the command involves large numbers of bulbs...
