btw the 150w cfl can be bought online. they get kinda pricey and you usually need a mogul size light socket but I saw some nice setups with the reflective hoods and the cfl as a package deal. I would still take a bunch of 26-68w cfl's placed all over the plants rather than just a big 150-250 watter on top. From what i've seen, cfl's seem to work best when placed all around the plants as far as yield goes. plus I heard that the high watt cfl's tend to burn out quicker and its cheaper to get a bunch of 26-68w bulbs. Do what you think will work best for your situation though. I am finally happy with the amount of light and placement of my lights for my box. Good luck
