Well you would only really need to worry about efficiency and heat if you had alot of them
In which case your dumb, go buy 1 600w
Par cept I'm not dumb. I'm 100% ScrOG, and 150/-W ballasts generate much less heat and so I could place multiples of them closer to my screen. Hence the interest.

EDIT:
its simple. hes saying he has 6x 30 watt CFL's and 1 70 watt HPS, probably not on the same power strip. ive seen his grow box.
That wasn't really my interest, thanks tho.
