check into induction lighting if heat is an issue. I use cfl's and im happy with my medical grade, way way better than any top shelf from a shop/clinic.

inda grow & igrow induction lights. (google it)

I havnt tried them yet, but they claim, a 200w setup is better than a 1000w hps

I would opt for quality versus Yield. especially if its for meds; setup a perpetual grow. divide your space into 2 areas. vegg & flower.
