M-man is right.
High pressure sodium or metal halides are better. There are specialty lamps for either of them that give some of both red and blue spectrums, but plain hps or mh lamps will do.
Spiral flourescents in small conical aluminum reflectors will work great on small groups of clones, but if you are going/growing for the big time then 4 ft. or 8 ft. flourescent fixtures are probably best.
