How to seal recessed lights from attic drafts?
Cold air drafts through my recessed lights and into my family room. Unfortunately, I cannot access the attic space above the recessed fixture. The recessed fixtures are Juno 5" IC rated high-hat cans with gold colored conical trim rings. I believe the bulbs are BR30 spot/flood lights. The bulbs are recessed 3" into the fixture and not flush with the ceiling.
I'd like to seal the 1/8" gap between the trim ring and the bulb with some kind of high temperature gasket. I'd like suggestions for something that's easy to find or make and inexpensive. It should be able to withstand incandescent bulb temperatures.
What I envision is installing the bulb through the gasket, so that when the bulb is tightened it will press against the gasket and seal the gap with the trim ring.
Any suggestions?
Thanks in advance.

This may cause a fire hazard altaring the original design. I'm sure an electrician will give an opinion.
You may need to address the problem of a negative pressure in the home causing the draft.

You may need to seal the whole can body to the ceiling drywall as well as any holes or slots up inside the can housing to reduce any air infiltration. Use products like aluminum foil tape, electrical duct caulk or putty or high temp silicone caulk to avoid issue with high temps produced by incandescent bulbs. Some older cans require vent holes in the upper internal areas to allow excess heat to escape so check with your specific brand....many also have high temp shutoff devices in the wiring circuit to limit temps below 150F...or switch to lower heat producing LED or CFL lighting or lower wattage bulbs if possible or needed if sealing holes creates too much heat buildup inside the can housing.

If you wish to try your thoughts/attempt at sealing the bulb to can/trim ring area, I would suggest locating some silicone membrane from a local rubber company/supplier or online source and cut to fit as needed....should be good for over 250F.
