Is there any way to insilate Non IC Recessed Cans without replacing them ? I understand and live with the fact that they are a substantial loss of energy through my attic. I was told that I could replace the bulbs with compact flourescents and insulate over the lights. Is this true? Also I was told that there was a "Hood" that could be placed over the light and still maintain the 3" clearance, but allow insulation to be place around the fixture and hood.
