Half moon fixture


I recently installed a half-moon fixture(similar to the one below) in my basement hallway. There is a sheet of drywall right above it, probably about 6 inches away. It has cracked the corner bead and a few other spots from the heat. Is this a fire hazard or does drywall have poor flammability rate? I don't care if the drywall cracks, its a hallway and nobody stops and looks. Should I just move to a fluorescent bulb that produces little heat?

Half moon fixture


is the bulb the right wattage for the fixture....? If the wattage is to great you will dry out the wires behind the fixture and that could cause a fire...replace with a compact florecent bulb they run much cooler

Would be my suggestion too if the light isn't on a dimmer. And my first wonder was if the bulb was too great a wattage also.

It's a 100W bulb, fixture is insulated and rated to 100W. The issue is how close the fixture is mounted to the drywall above it, and being an open fixture the heat has nowhere to go but up.

Isn't physics great!!

You say there is a sheet of drywall above it. A ceiling I presume?? Double check the instructions about how close it could be mounted to a ceiling??
My concern is the heat from the 100W you mention. If it's a screw in type bulb, and not on a dimmer, I'd try a CFL, for less heat. If it's a different type bulb, I'd get a lower wattage of that style.

The instructions were generic for 5 types of similar fixtures(not even the one I bought) and didn't even mention how to ground the sucker properly... but hey it matches the rest in the house!

No dimmer, its a hallway light so we need it bright to get up/down stairs. It's a screw-in type, I'm sure a CFL would fit.

Here's a pic. You can see the drywall tape starting to bleed and peel.

Nice light.
Yeah I see break in the corner of the soffit. I'd try a 23W CFL.
