As for rated color, I would go 6500K for a single lamp - closer to sunlight. For quad fluorescent, I mix two 6500K and two 4800K(?). But frankly, I don't think it's all that important.

This is why the (Grow) LED lights only emit in the red and blue spectrum and not in the green of middle spectrum.
This is why you see them looking purple.
This is not to say you cant use the ones made for us you just get light the plants dont need.
When they build the LED lights for human vision they mix all three spectrum's and we see it as white or yellowish light depending on what they use.
Speaking of this some guy was on a bicycle last night with a LED head light on his head.
It almost ran me off the road.
