Have never seen or heard of this problem before. We put in some closet lights that are a 12inch light with 3 60w bulbs in them. These lights are mounted to plastic nail on outlet boxes not the round nail on boxes for lights. We come back the next day and the lights and boxes are hanging out of the ceiling because the boxes are melted and distorted enough to come off the nails. The 6/32 screws also loosened because of the heat. Anyone had this problem with these cheap plastic boxes? Could the light be causing this much heat?
