 o
one light fixture bulb burns out after 1 month, why?

Not sure this is a problem, but thought I would ask here, I recently had a an outside light which was over the middle of my garage door removed, and replaced with two lights, one on on either side of the door. The light bulb on one of the lights keeps burning out after a month. I buy the rough service bulbs but that doesn't seem to help. I had an electrician check the wiring, he said everything appeared ok, but it bothers me that it keeps happening, and only to that one side. The bulb on the other side has lasted about 3 months before it had to be replaced. So while the bulbs aren't lasting as long as I think they should be, this one bulb appears to be a problem. If the wiring isn't a problem, any opinions on what it might be? Should I try to buy more expensive bulbs> These bulbs are hanging in the upside down position, would that be decreasing life, and if so, why one bulb and not the other? ANy opinions welcome. Thanks!

Vibration is a fast killer of incandescent bulbs.

Is the one blowing on a more exposed corner?

There are coated bulbs for 'rough service' and other bulbs that contain better filament support.
The coated bulbs are not designed for vibration, but breakage of the glass.

Try a ceiling fan type bulb.

Verfiy that the lamp is really burned out. The fixture socket may be the problem. Sometimes the center contact point is deformed and not making good contact.

It is on an outside corner so perhaps the greater exposure is the problem. Would a ceiling fan type of bulb be suitable for outside use? I will also try the latest burned out bulb in another fixture to see what happens. Thanks very much to both of you for your suggestions.

If you don't have them on a dimmer, photo control, or electronic timer switch, replace them with compact fluorescents. CFs withstand vibration and physical shock much better.

Depending on your location the CFLs may have problems with cold weather.
