LED lightbulb light isn't that high quality.
As far as I know, the current tech LED lights are blue LEDs with a yellow phosphorous. Blue+Yellow looks vaguely white to humans.
However, it isn't really white light. It makes thinks look strange, because it is missing entire chunks of the spectrum.
Go for good florescents, they approximate "real" white light better, and are also very low power...
