It's Lumens that count. All the watts that replace watts stuff doesn't add up to anything. It's a hyped up energy saving thing for homeowners and replacing incandecents.

Most of the bulbs you get also have the Kelvin temp on them 6500 is about daylight, with not much if any at all in the red spectrum. I got my seedlings going with 2x32 watt tube florecents, and can't be more happier. Kept it 1" off the plants, and then switched to MH after a week. No stretch at all, and growing like a weed after only 2 weeks.

CFL are great, but you can get a MH setup cheap on ebay if you look, or build your own on the cheap too. I suggest using an old ammo box as the ballast container drilled with holes for air to cool it down a bit. Use 4 long bolts through the transformer, with an stand off on the bottom for air circulation under the transformer, strap the caps to the sides with some zip ties, and an electric cord 25', socket, and some hardware, and your done.
