I just installed them today January 8th 2019 so I can't comment on their durability. I've replaced fifteen 65w lightbulbs with these and they look great. Incidentally, the dimming function works excellently with GE Z Wave Smart Dimmers. Both a paddle style and a traditional toggle switch (which doesn't click). I can still "pronounce" them with the same brightness as my old lightbulbs. They're currently $50 for 16, which I think is a great value. while. They arrived well packaged and well protected. So far no complaints. On January 18, the clapping seemed to have stopped. 08/08/2021 (2.5 years later) Update: 2 lightbulbs stopped working. The knocking never stopped, I don't know what I was thinking.
