What he said ^

But if you are buying a few 125W CFLs (not 125W equivalents) then you would probably be better of getting an HPS or MH system. It will cost the same to run them but have a slightly higher initial purchase cost.

I'm not saying CFLs are bad, I am using them now, but it is because I am REALLY broke haha. If I had a few hundred bucks I would go HPS/MH all day.
