Subject: RE: BS: light bulbs- lifetimes- switched on/off?
They used to make a small thermistor that you inserted into the base before putting in the bulb. I haven't been able to find one recently.

Years ago I scavenged a thermistor from an old television set and wired it into a slide projector. Slide projectors are notorious for the short life of their bulbs but with mine the thermistor burned out before the bulb after several years of use.
