IIRC, incandescent light bulbs generate photons over a wide range of frequencies, but LED are more narrow.
This is a similar issue to the difference between fluorescent bulbs and incandescent bulbs.
Both are very poor substitutes for incandescent light bulbs.
When we were told we would no longer be allowed make those bulbs we really screwed up. There is no good substitute for them. Actually the so called Halogen lamps are, but they are costly, don’t last very long and give off more heat.
Wonder if we will ever get our head out of our collective A and deal with bureaucrat stupidity?
