Yep, any bug you can hear walking around at night is too big to be a house guest.

I bought a dozen 150W floods in 1994 to have on hand for a large contract job I was doing. The client supplied all our lights so I came home with a full case. Floods feel good when working under them in a cold shop.

I probably could cover the pans with insulation since the can enclosure is at least 2 cubic feet. I doubt the temp rise would be significant even if 100W was escaping upward.

Tomorrow morning I will check around the cans with an IR gun before the sun comes up. Right now the temp around the cans is the same as the rest of the ceiling. Inside air is 63F, outside it's 42F.

There is actually more temp drop (2F) where the ceiling meets the walls at the header plate. The corresponding area of the soffit outside shows a 2F rise. Makes me wish I had paid more attention to this before the soffit went up. The headers need foam but I'm not crawling over there again.
