Question Burning out bulbs...

Hello all,

I just moved into a seventy five year old house and I have two lights that frequently burn out as I switch the power on. The house is semi upgraded electrically. I have 100-amp service distributed from a load center with some wire romex and some cloth wire (presumably from the old knob and tube). Any ideas as to why the bulbs burn out as the power is switched on? Thanks for any and all help.

Troy

Just one thought...
Look for some 130V (not 120V) bulbs and try them. The voltage into your house may be a little high, in which case the 130V bulbs should last longer.

Bulbs that burn out frequently are often subject to excessive vibration. A ceiling bulb that is under a walkway is an example. Try buying a rough service bulb for that location and see if it will last longer. Measuring the voltage is also a good idea. Perhaps the voltage is some higher than 120 volts as a previous poster suggested. If that's the case you will have to fix that problem or try a bulb rated for a higher voltage.
