Without having measured it, I get the impression that LED lamp failure follows the typical "bathtub curve" and that all mine that have failed so far have been on the downhill slope at the start. These were various brands and odd shapes when LED bulbs were still immature. Current "Feit Electric" bulbs - outfitted the house with them top to bottom when they were about 30 cents/bulb due to a government rebate + deep discount at Lowes, actually seem to live up to expectations. I'm not sure when I've last replaced one, and a big box of them bought later for spares (at about $1/bulb) is so far mostly unused. The other thing is that even crappy LEDs with low efficiency and reliability save so much electricity that you come out ahead, compared to a 1000h incandescent, even if they do fail after 1000h as well. Maybe not better for the environment, but microeconomically OK.
