They do sometimes flicker when they're in a traditional dimmer set at an intermediate level, even though the ones I've bought claim to work with a dimmer. That's frustrating.

But I haven't had any outright failures.

If it helps: I bought mostly SANSI bulbs off Amazon.

I do remember in the early days of LED bulbs, many were quite unreliable, especially dimmable ones. It was probably more the electronics in them failing more than the LEDs themselves?

But now days LED bulbs seem much more reliable and I very rarely have to replace them. In fact the only bulbs I can recall replacing in the past 18 months living in my current house were some old CFL bulbs that hadn't actually completely failed, but had gradually become a bit too dim.

Certainly, now days, I need to replace bulbs far, far less often than in the old incandescent days where it was a regular chore in any house.

(Also, now days I avoid using old-style dimmer switches, and even removed some in one house I lived in. Better to get a smart bulb with it's own built-in dimming if you want it.)

Are you sure your power isn't bad in some way?

Would be much easier instead of embedding an AC/DC converter inside each bulb that we now get standard 12V DC for lighting throughout homes - That would centralize the voltage sensitivity and allow larger circuits / capacitors to regulate this.

IME the worst are the ones that get really hot. I've had multiple (rather expensive) LED spotlights like that in my kitchen which never lasted more than a year or so.

They’re Philips Hue bulbs, a mix between LWB010 and LTW001, but even the cheap supermarket bulbs have lasted so long I also couldn’t tell you when I last changed them. Some of them have been in the house longer than I have.
