    Light Bulbs Blowing Regularly
    The lights in our house keep blowing, even after bulbs have been replaced. It takes weeks or months, but it is getting crazy. First a bulb or two in the ceiling fan, then the attic, the bathroom light, then both of the upstairs hallway lights at separate times, then the back porch light, and now an entire strand of white lights used for decoration. This has happened in under a year's time. What could be the cause?

    A loose Neutral(white wire) will cause voltages to go High and Low, since it effects the whole house, I would have all Neutral connections checked from power company through meter and to Electrical Panel. I would tighten hots and grounds while things are open.

    Due to the wide spread nature of your problem, I would agree with the previous post. However I'll put my two cents worth in for others that may have a similar problem with just a couple locations that seem to have a short life. I had a Bathroom and a closet bulb that seemed to have an extremely short life. They were close to my A/C Air handler. I concluded the vibration from the unit was more than the filament of the bulb could take. I replaced them with compact fluorescent and they haven't been changed since.

    Neutral issue, higher-than-normal supply voltage, or frequent power surges.

    If the fixture is old. The tab for the hot in the socket can be to far from the bulb. Turn the power off... pull the tab tward the bulb

    Vibration is a primary killer of light bulbs.

    Light bulbs also have the nerve of all dying at about the same time.

    And the one that's harder to figure out is a bad manufacturer's lot.

    Since it it happening everywhere, I think finding neutral problem is better solution than
    Installing 130 Volt Rough Service Bulbs. Normally they never see 130 volts, and running at 120 volts they last longer. May be a solution. Do you ever see brights get bright or dim at times(more than usual variation?)

Hi. The light bulbs in my kitchen and dining area keep blowing out. I hired an electrician to do some other work, and he said my bulbs just blew. However, after I purchased new bulbs, they still blew out. Some of the bulbs are halogen and others are incandescent. I don't have any problems with...

We've already assessed that in this apartment, we are getting about 124 volts at the box. I've had a big problem with regular incandescents blowing, but will soon be replacing them with 130v bulbs (as soon as the current 120v ones burn out). So that problem should be solved. However, my...

I added a third light (one that had been sitting in my closet for years) to one of my tracks which immediately blew the bulbs in the other two lights.
