I have a light bulb fixture on the ceiling in one room of my house that holds 3 bulbs.
The previous owner installed it to make the room extra bright, for certain work and tasks to be done here, that simply require a bright environment.
I used to put in 75 - 100 watt incandescent bulbs in the fixture.
Most of the time though one of the three bulbs would burn out super fast (like within months if not weeks... I got tired of changing them all the time, especially because its such an ordeal with the big, heavy, decorative screw-on glass cover mounted to the fixture). Burned out bulbs would leave the room unevenly lit, and generally not bright enough.
At the same time though 3 100W bulbs were kind of making you squint a bit, because it was SO bright...
I wanna say 2 years ago, maybe 1.5 years ago I saw some 60W-equivalent CFL bulbs on sale and bought a package. I used 3 of those in this fixture, and TADA! No more burned out bulbs since then, and generally perfect lighting conditions (except for the first minute when you turn them on, but oh well...)
It's been going good for probably a year or longer.
About 3 months ago I noticed that one of the CFL bulbs was making a buzzing noise.
I changed it with a newer bulb and that fixed the problem, I figured the bulb might have had a factory defect, as they are supposed to last 10 years.
This morning I noticed that the light is making a buzzing noise again!
Haven't been able to check which bulb it is, but come on!
What am I doing wrong, what can I do to prevent this from happening to the bulbs?
I find the noise not only annoying but I am also concerned about safety: I had installed one of the bulbs in a fixture in the basement once, and while I was down there I noticed that the light started buzzing, then flickering. When I looked I saw it was practically burning on the base/ballast. I turned the switch off immediately and the flames stopped... Hasn't happened with any of the other bulbs since then (I bought 2 packages of 8, one of which I didn't need to open yet). Again I assumed at the time it was a defect with one of the bulbs.
Is there anything I need to be aware of regarding lighting? I figured each fixture has 120V on it, so it shouldn't matter what bulb you put in, should it?
Oh, and these are no dimmable lights.
EDIT: It took me forever, but here is finally a picture of my setup I don't see why there would be any heat issues arising, especially since the fluorescent bulbs don't get hot...
