We use incandescent bulbs as heaters to keep water pipes from freezing in the winter. When put in a brooder lamp housing they’re safer than dedicated space heaters on a thermostat and useful for places where heating tape isn’t practical (eg around a pressure tank)

We usually go through 8-10 100w bulbs a year across the three pump houses and crawl spaces We have to maintain. Running continuously they only have a life span of a couple months.

Very unusual situation of course. Idk i think we last bought LED’s for the actual inside of the house maybe 5 years ago lol.
