Bare incandescent bulb clearance from wall

786 Views 10 Replies 5 Participants Last post by  helium44
Hi,

I'm wondering what the clearance is from a bare incandescent bulb to a wall (drywall). Does it change based on the wattage of the bulb (60W vs 100W)?

(From what I've read it seems it needs to be enclosed and/or 12 inches away but I'd like a definitive answer.)

Thanks

Don't think you are going to find a definitive answer. If you can't hold your finger on the wall while the light is on, its probably getting to at least 130 degrees F. That is likely hot enough to burn the paint and paper drywall covering, over a period of time.
Where is this an issue? Open bulbs are not allowed in clothes closet.
This is not in a closet. The bulb at its nearest point is an inch away from the wall.
Going to damage the paint. Try a CFL or LED
Way to close. I would use an enclosed light fixture
Ok, thanks for the replies. It's strange seeing as it was installed by a professional, although it was 20 years ago.

I can't imagine a scenario where you would install a fixture that close to a wall. Can you enlighten us?
More likely the wall was installed too close to the fixture.

It's in a small furnace room

Yes, I just asked someone and it turns out the wall was moved during a renovation.
