I have some of the more expensive smart lightbulbs from Sengled and they barely lasted 2 years. I’m coming up on 2 years with my Wyze bulbs (I’ve got about 10 total) and so far they haven’t had any issues that I’ve noticed. But I’ve slowly been replacing my sengled bulbs as they die with the ones from Wyze.
I’ve not tried any other brands of lightbulbs, so I can only compare those two.
