My house eats light bulbs


So it seems that my house enjoys a steady diet of incandescent light bulbs of all type. It's blowing bulbs all over the house, some even no more than two weeks old. I've had my utility company come out to check my service at the pole twice, but that hasn't resolved the problem. Any ideas what may be causing this? It definitely seems to happen more in the warmer months than the cooler ones.

Thanks,

Ash

Have you measured the voltage?

Do the same light bulbs come on very brightly some of the time and dim some of the time?

Are the light bulbs in a first floor ceiling that gets a lot of vibration from walking up above?

I haven't measured the voltage at the lights, but the outlets in my house get between 120 - 123 volts.

Most of the lights that have had issues are in ceilings or fixtures that wouldn't receive any vibration.

They do dim at times, however. I haven't noticed an increase in brightness though.

Buy bulbs rated for 130 volts.
You'll have more luck with those.

Cheap fixtures with bad sockets.

The lamp sockets are typically riveted together, with the rivets acting as wire terminations as well as structural.

Carefully look into the sockets, and you may see signs of scorching where the rivet attaches to the shell. That indicates a loose/bad connection, usually for the neutral conductors.

Such bad connections can cause excessive heating in the socket, literally cooking any light bulbs from the base resulting in short lamp life.

Try replacing one or more fixtures, and see if that helps.

To add to what KB said, if the lights are on the same circuit, look for loose connections in the panel, and at the first switch location.

Why 100 vs. 130 v?

Wouldn't higher rated bulbs than what the fixture requires, continue to blow bulbs from getting too hot.

Thanks for all the replies. I think KBSparky is probably correct in that it's cheap fixtures. They're original to the 16 year old house, and were probably construction grade when they were put in. I'll start replacing them slowly and see if that solves the problems for good.

You are confusing voltage versus wattage. A 60 watt bulb is a 60 watt bulb whether it is a 120 volt bulb or a 130 volt bulb. A 130 volt lamp(bulb) will usually last long in a circuit supplied with 120 volts.
