Including providing an omnidirectional source in the way an Edison
bulb does. Also, "daylight" color in both LEDs and CFLs means a color
temperature around 3000 Kelvin, rather than 5-6000 K, like you'd get
from the sun or a halogen.

Say what? I can get high power white LEDs from Lumileds in
6500Kelvin, 4100Kelvin, or 3000Kelvin, pretty much any white point
you'd want (cool, neutral, and warm). Your statement above is
incorrect for LEDs.
