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.
But that would greatly reduce the bulb's life.
The Reveal lamps aren't new -- daylight-balanced tungsten lamps have been
around for at least 50 years.
