I may be installing some canned recessed lights in a attic room ceiling.
This room will be used as a storage area for all my hunting clothes, gear,
etc.. The room is 12 x 12 with a 8' ceiling. Two of the walls are 12/12
sloped to the floor and the ceiling is approx. 32" x 12'. This room will be
unheated other than leaving the door open. It is entirely insulated. The
ceiling will be insulated with r-38 13" thick batts which is thicker than
the height of canned light fixtures. The fixtures I have looked at ( Juno,
Halo ) say that their IC fixtures are safe for insulation contact but I am
in doubt whether it would be advisable to place insulation on top of the
fixture to completely encapsulate the fixtures with insulation. Are these
fixtures normally completely covered over with insulation or do you cut a
hole in the insulation so that the top is open to the air with insulation
touching only the side of the fixture? I asked at the box stores and got
different answers. Thanks in advance for any advice.

While helping out my daughter with a remodel of her house -- it's around 40
years old -- there were some recessed fixtures in her ceilings, in the
basement finished room, and in the halls. In the halls, I spray painted the
inside of the fixture with a high gloss white enamel, and put in the spiral
fluorescent lamps. They are a lot cooler operating, and the white enamel
paint reflects the light better. I did the same with the old Kirlin square
recessed fixtures in the basement room. I painted the inside of the
fixture, and the reflector also. The fixture is much brighter now, and runs
a lot cooler with the spiral fluorescent lamp. There would be little chance
of a fire hazard with this combination.

Contact Juno or Halo and see what they say.

Not sure - but I installed Juno IC cans in my attic. I cut the
insulation around them and did not insulate on top of them. They have a
thermal safety switch on top and it just didn't seen like a good idea to
insulate it.

Yes, IC fixtures are rated to be completely covered in insulation.

UL writes the standards on that issue and the makers have to meet
those. Thats what the makers will tell you if you ask them. It is why
many IC fixtures have lower wattage requirements than the non-IC types.

FWIW: Incandescent fixtures will be far cheaper for a rarely used
storage area. If you are in there one hour a week, you might spend as
much as $1/year on power.
