bad fixtures?

My house has the older wiring, black and wht with no ground wire. There are a few fixtures that continually have blown bulbs. Does this mean the fixtures are bad or could there be other problems?

Are they near slamming doors or other vibrations. If so try some compact fluorescents. They have improved in 5 years. If your house is wired with aluminum wire try tightening everything in the panel and the fixtures.

I believe the all AL wiring should have grounds. I think that we are going back a little further than that.

Turn off the elec. and try tightening the screws at the receptacles. How loose are the plugs when you plug them in? It may be time for new receptacles.

Another possibility is voltage. Where I live we are supplied with 125 volts which blows bulbs very quickly. I found that you can get bulbs (ask for 'lamps') at a wholesale electrical place that are rated for 130 v. Fixed the problem here. You'll also be amazed at how cheap they are.

If the problem is voltage, you will likely be blowing bulbs in ALL of your fixtures. It is most likely vibrations - typical incandescent bulbs are very sensitive to vibrations. If you look at a clear bulb, sometimes you can actually see the filament bouncing around. Eventually that filament will break prematurely. Ceiling fixtures underneath high-traffic floors and wall sconces near doorways are particularly vulnerable. As suggested before, the compact flourescents work nicely (in addition to saving you as much as 65-75% in energy costs).

If you have situations where the light flourescent light is just too harsh, or an fixture where the bulb is exposed and just doesn't look nice, you can buy vibration resistant incandescents. They won't last as long, but they will help. Ceiling fan bulbs are one example.....
