If you are really seeing that much heat it sounds like a design problem. The whole idea of a can is you use a reflector bulb that sends most of the heat down, out of the can. Maybe the actual hot spot in a CFL is not anywhere near the focal point of the reflector. I would almost say I am sure of it.BTW as an aside, I am having 100% luck with the normal spiral bulbs and I am just getting cheap ones from Sams and Home Depot when they are on sale. I am coming up on 2 years on the ones in my garage and out in the post light. (all on motion detectors)
