Counterpoint: I've been using Hue bulbs for over 10 years, currently have around 120 lights operating and have had maybe a 5% failure rate (mostly 2nd and 3rd generation A19 bulbs). Flicker due to PSU failure, some completely dead bulbs, some which have lost specific colors in the array (maybe FET failure) so they turn weird colors (like green or purple) at certain white temperature settings.

I suspect the cause is mostly heat-related. As newer bulbs run much cooler I expect reliability will be better, but the product line is definitely not bullet-proof.
