As these threads come up, I’d offer a thought.
Last year in one of these, a Freeper put in a link to a company called national hospitality supply. You can find them on the web.
They sell regular cheap bulbs and a bit more expensive commercial version that lasts years called the decade bulb.
I bought a bunch of the 75 and 100 watt decade bulbs from them. Very happy.
CFLs are terrible. LED’s still very expensive and I’m not yet sold on their light spectrum. So I will be stocked for ten years with normal incandescents and wait it out.
A friend of mine is into industrial lighting and he does installations, etc.
He talks “temps” of lights, not meaning the thermometer temperature, but the spectrum-equivalent of what temp the light would have to work at to match the spectrum.
He also says CFL’s are just about the very worst spectrum lights for your eyes that have ever been invented!
Plus I guess they put out a huge amount of electromagnetic noise that can screw up sensitive instruments.
