They're rated for 105c or 220f for about 3,000 hours. Lowering or increasing the temperature around the cap by every 10 degrees will increase or decrease the life of the cap by about half (hotter) or double (colder). So in normal situations where you're not utterly baking the thing in a recessed can, they might get to 140f in a flush mount light fixture. So that's 8 x 3,000 hours life, which is more than enough to ensure life of the CFl. This stems from in the past where people cheap out and put standard A-lamps in recessed cans. Then they are still doing it with CFL's. Standard CFL's are not rated for such use. Nor were standard A-lmps frankly. They wouldn't necessarily burn out early, but it's just a silly waste of electricity because the fixture was designed for use with a reflector lamp. A standard A-lamp doesn't properly reflect the light downward. The 105c caps are actually guite good. They’re rated for 105c or 220f for about 3,000 hours.
