Can light touching air duct insulation
 
If I put a 4 inch non ic can light thats 45 watts touching the insualtion around the air duct, what are the chances of the insulation on the air duct catching on fire? Or what other problems may occur?

Make sure the recessed light is IC rated. IC rated luminaires are rated for direct contact with insulation.

For the purposes of this discussion, you can consider the chance of fire to be 100%. (because no one will know the actual odds, and no one will advise you to put a non-IC-rated fixture in contact with insulation.)

Other problems that may occur:

If the duct vibrates during operation, you'll most likely burn out light bulbs faster.

Just to clarify this thread, the OP added "non ic" to his/her post after I made my post.

Apparently he/she didn't like our answers because he/she went to the sister forum for electricians only, lied during registration, and then posted the same question:

If you going to installed a recessed can luminaire next to the air ductwork you must have IC rated can do NOT use the non IC can at all due the safety reason or just move the ductwork or relocated it.

Myself I will try to advoid the ductwork much as I can as long I can keep at least 3 inches away from it.

Merci.
