MD, I know what you're saying about the whole cheesy hotel thing, now you've got me having second thoughts. The reason I am asking the question and that got me considering the installation myself is a guy I know had a recessed fixture in his bathroom and simply took out the old incandescent and replaced it with a heat lamp bulb, says it works great and feels good right after a shower. I would have thought he would have had an issue with the thermal cutout, he said no, it's worked fine for years. I always figured you would need a special housing but didn't know what kind. I wonder if it's all much ado about nothing or is ignorance so blissful it can ignore the laws of physics.
