Apparently, its continuing with LED's as well, as I've just had the 3rd "burn out" yesterday. I'm too lazy to count the number of bulbs (~20) and compute my own personal failure rates and expected lifetimes, but my seat of the pants estimates are that the 10 year lifespans are a bit optimistic, given that all three died in under a year (three different manufactures too). The ones that died were in open fixtures, so heat shouldn't be a problem either.
The first couple I took apart to determine if the LEDs were the problem (they weren't, the power supplies are the weak link), this one I'm going to send back to Cree to see if they actually honor the 10 year warranty, on my 3 month old bulb.
