So Im a reno-newb and bought potlights... but then I found out that if you are putting them in any areas that are surrounded by insulation, you have to have them in an insulated cabinet (see pic).

So.. I bought this:

Anyone know where I can get a deal on these? Im not too keen on paying $30 a cabinet at home depot when I bought 6 potlights for $30. Can the potlights I bought work in an Insulated Box?
