Unfortunately I can't do that. The can was installed when the house was
built and it's a sheetrock ceiling. I guess I could check, but that
will be a last resort, and I'll just replace the fixture while I have
the ceiling torn apart.

The fixture should be removable enough to check for being covered by
heat insulation - a major no-no!
