My initial lighting startup is 4 100 watt CFL's, 6500 K at 1600 lumens per. These are in y adapters in a clamp lamp for the time being. I have a four socket lighting fixture that once wired and mounted onto a wooden piece will have 8 of these same bulbs in y adapters.

4 x 1600 = 6400 lumens
8 x 1600 = 12800 lumens

I'm using Bright Effects 100W replacement (really only uses 23 watt) CFL's, 6500 lumens. These were the brightest and highest lumen and watt I could find at the DePOT and Lowe's. I can always get another fixture and more bulbs, but am only dealing with ten seeds and hope that no more than 5 are male...
