The CREE lights are very good, as are Soul Semiconductor LEDs. I have a 
mini-maglite conversion running with an SSC-P4 LED. It's blindingly 
bright (~130 lumens) for a little 2-AA cell flashlight. I can testify 
that the light is white. Incandescent bulbs cast a dirty yellow light 
next to the light from this bulb.
