Or when they switched to LED and actually lasted a decade, like now?

LEDs with Edison screws on them don't last that long. Maybe Siemens or some other brand name manufacturer, but the cheap Chinese ones last only a few months.

It's the heat buildup that's the problem. Disassemble them, slap a CPU heatsink on it and yes, they will last forever.

Seems like a manufacturer problem. I've have the same LED bulbs in my house for 5 years plus with no replacements. Various makes too .Some of them came with me from my old house. No idea how old they are. With incandescent bulbs, I used to have to replace at least 1 a year. I used to keep a stock in the back of a cupboard.

The problem with led bulbs is that they are build to operate at their limits. It's still within spec, but just barely which is why they break so quickly. If you would reduce the current by half they would last for decades.

But of course Big-Light doesn't want that, so after the initial well-build led bulbs became standard they switched to cheaper designs with less internal led modules for the same brightness.

As I said, the simplest solution - better cooling.

Make, model and price please.

You're saying the cheapest possible products don't last long, while the more expensive ones last for years? Can't be.

Just saying... they weren't advertised like that at all.
