Default Banning incandescent lamps?

P.S: The yellowish "Warm White" bulbs SUCK!


So, which ones are best for color?


Most bulbs with 20+ watts. The 13W bulbs just weakly bleat out yellow
colors and aren't good for much of anything. I much prefer anything
with a 4000K or higher rating. Bluer is good, yellower is bad. Higher
CRI ratings seem to go hand in hand with higher Kelvin output.


Wiki up the latest info and best CF compilation I've seen yet:

See the pic with the 4 styles of lamps? I much prefer the lefthand
one.


That's interesting, because I would have thought the ones that were close to
incandescent temperature were more pleasant for reading and working. But
photos like that are tricky. Having done a lot of industrial photography
with weird lighting, my reaction to that photo was that it probably isn't
much like what the scene looks like to the eye. Interrupted-spectrum
lighting often looks different on film; I assume the same is true with
digital photos.

Anyway, I'll have to get a couple of new ones and try them. I'll miss my
dimmers (I made a bunch of them years ago, and I've replaced them all over
the house with commercial ones, over the years) but it will be worth it.

Thanks for the tips, Larry.
