Default Porch light keeps blowing bulb

SNIP to here to edit for space on making lightbulbs last longer

IIRC they used to make things for the bulb socket. One was a diode, the
other was a thermistor, I think. Are those still around and useful?


I don't know how available these are, but I don't find them useful.

I tested a thermistor that claimed to double the life of light bulbs,
for dimming that accounts for life extension. I found enough dimming to
account for a 50% life extension. This reinforces what I heard from
experts about most lightbulbs not actually suffering significant wear from
cold starts, but merely becoming unable to survive a cold start a little
before they become unable to survive steady operation.

It appears to me that use of a 130V version (available at Lowes last
time I checked) works at least as well, without wasting that small amount
of power creating heat in the thermistor to keep it fairly conductive.


Using 130 volt bulbs when your voltage is 115 - 120 also makes them run
less efficiently also.
