Cree LR6 housings and foam insulation??
I'm looking closely at the Cree LR6 as a perfect solution for lighting in a basement wine cellar because of the low heat that it puts off. Because this is a cellar though, the ceiling (which is also the floor above) needs to be super-insulated, which means spray-in foam insulation.
I know you usually shouldn't spray foam around high wattage housings, even IC because many of them are designed to be slightly "lossy" and let heat escape out the back, but what about in this case? I know there's a heat sink in the module that takes heat away from the LED chips, so there must be some heat in there, but it sounds like it's only a couple watts.
Does anybody have experience using LR6s either in existing cans (who's?) or in Cree's can when they are closely covered in insulation?
