I have recessed ceiling lights that are rated to 75W. I use par 16 halogen reflector lightbulbs (sylvania brand), which are what was being used when i moved in. In the past 15 months, 6 different bulbs have failed. Two times, the actual filament casing exploded. Also, four different lighbulbs have failed in the past 15 months. The metal flange that holds the glass in place falls off, and the glass then falls off, shattering on the floor.
I called sylvania and they said there have been no reported problems with their bulbs.
