Aren't Reveal just hugely overpriced incandescnets??? Maybe they
last
a bit longer but so what?

Some people like the light they put out. Here's GE's own claim:

"What Makes GE Reveal Bulbs Different

GE Reveal bulbs make colors "pop" in a way they don't with standard
incandescent bulbs.

Why? The rare earth element neodymium that's in the glass. (It's what
gives these bulbs their distinctive blue color when unlit.) When these
bulbs are lit, the neodymium provides a pure, clean light by filtering
out much of the dulling yellow cast common from ordinary light bulbs."

You could just increase the filament temperature a little and get the same
effect. But then, they couldn't advertise a high priced lamp.


Photoflood bulbs do just this, they're also rated to last a whopping 6
hours.

Efficiency and color temperature increase with filament temperature, but
unfortunately lifespan decreases exponentially.

Standard incandescent is about to go away anyway.
