That's interesting as in their on-line FAQ, Cree says they approve of 
installation in can fixtures. We've had 42 W CFLs in there for the last 8 years 
and never seen evidence of overheating. However, the light is cycled a lot and 
I suspect the failures we've seen are related to that. Cree again states that 
power cycling is harmless to their LED bulb. I guess I'll get to find out!
