Hello, I would go with a 250 to 400wt HPS/MH switchable electronic ballast and reflector. I think this will produce the best results for a 2 plant closet grow. Will cost you about 95 to 175$ complete light system. You can always find better deals on craigslist or e-bay. It will add anywhere from 75$ to 120 dollars at the high end to your electric bill but you will have nice dence buds and your yeilds would always be better than CFL"s when an oz grown under CFL's looks like a QP and is full of air...you will barely get that per plant using CFL's.Your hard time spent will be more frustrating at harvest if you wanted something that will last and have goo medicinal values. Hope this helps take care
