I am replacing some 6 plus year old flush mounted fixures with new ones. As I am taking down the old ones I notice 2 things:
1. there is no insulation between the fixture and the ceiling.
2. the foil between the light bulbs and the fixture is gone. (just a thin layer of padding of some sort).
I got in the attic above the fixtures and the blown insultaion is very warm to the touch. Should I take down all the fixtures and replace them? Is there to much heat transfer from the light bulbs throught the fixture to the insulation in the attic? Or am I worrying for no reason?
Buy IC rated fixtures. They have a high temp cut off if the fixture gets to hot. IC rated fixtures are usually the reccessed type (can Lights). It's still a good idea to keep the insulation from not touching the fixture. The use of CFL light bulbs will significantly lower the fixture operating temp. Never install bulbs with a wattage rating that is higher than the fixture allows. The max wattage is printed on the back side of the fixture or in the canopy. This is most important.
