> Maybe you're just buying cheap poor quality bulbs?

All of my led bulbs that failed were either cheap poor quality bulbs or expensive poor quality bulbs.

I have a hard time determining the quality of a bulb without running it for 2 years, and then it's a little late.

And then you have the mix and match problem. The same model number from the same manufacturer purchased at the same retailer gets different internals. So if you've got a room with 6 can lights, when one stops working properly, you have to search your inventory to see if you can replace just one, or if you have to replace all six. As long as the color is roughly the same, I don't mind a difference between rooms, but it's unacceptable when one lamp comes on instantly and the other five take a moment, or when they don't dim together, etc. I never had this problem with incandescents, as long as you bought the same color type and wattage, you could mix and match across brands. I did have one fixture that had tight tolerances for the fashion shaped large sphere bulbs it wanted, but that was fixable with a copper shim that cost one cent (and some paint on rubber insulation around the edge)
