Is it OK for insulation to touch IC-rated lights?
Mike writes from Chicago, Illinois: “In my new construction home, the electrician installed 6″ IC-rated can lights in the ceilings. The attic has R-30 blown-in insulation touching the lights. However they all go off-on after a while (1/2 hr) from over-heating. The electrician said that the insulation should not be touching the cans, even if IC rated. I disagree. I even tried to lower the bulbs as much as I could. What can I do?” Answer: IC-rated lights are for use in insulated ceilings. I recommend contacting the manufacturer of the can lighting and asking for assistance.
