Question

Sweet smell from light fixture


I have a couple of light fixtures that I bought from Lowes a few years back. They are very non-discript, two-bulb, ceiling fixtures. I have noticed over the past year that if these fixtures are on for any period of time they give off a distinct "sweet" smell. I think the fiberglass insulation material or maybe even the adhesive adhering to the fixure is giving off this smell. Question, do you think this is a safety issue? What should I look at to make sure the fixture itself and the electrical coming to the fixture is OK?

if they're older style ballast, it could be heating to a point where offgassing is occuring from the adhesive. likely not the fiberglass insulation.
replace fixture with electronic ballast fixture and the problem should go away. if they're glued too tight to pull without a mess, just swap ballasts and rewire.

I don't understand what you mean by older style ballast. These fixtures where purchased about 4 years ago (new) from Lowes.

Very similar to these:

Make sure your putting a to high of a wattage bulb in the fixture. If your worried about starting a fire install a twist bulb uses less electricity and you get the same if not more light from the bulb

good point, read the fixture and be sure you have the correct bulbs first off.
the older ballasts (they still make them too) are the big rectangular heavy ballasts. newer ones are very small, and i don't think they even get hot.
open the case and see what you have if the bulbs are correct.

Hah there's an anti-marijuana ad on this thread. Maybe someone put a stash in your fixture cans.

DangerMouse, there are no ballasts contained within an incandescent fixture.

But if you wanted to cut down on the heating effect from those 100 watt bulbs, you could install some swirly-type compact fluorescent bulbs in there.

I'd suggest using some 23 or 26 watt cfl's and see if the smell is still present after being on for the same amount of time.

Seen this problem before, IF you bought the "contractors package" that contains two or more fixtures, and the lens are molded fiberglass instead of glass, and this is what it certainly sounds like. Did you change one or both bulbs in the fixture(s) in question lately and put in a bulb with a larger wattage capacity than it had in it? IF SO, then the heat from the bulbs is warming up the fiberglass lens and giving off this "sweet" smell. I have one of these now that I changed out with a brown spot on the lens where the bulb was too close and it really got hot. Good Luck, David
