i'm using a homemade reflector with 7 26 watt cfl's (6500k) 1600 lumens each, they are 2-3 inches from the top of the plant, but don't give off very much heat, the effected leaves are at the bottom of the plant, top leaves seem fine to me. i'll try to get a good whole plant pic, it's an aggrevating process posting pictures right now as i'm using a cell phone...
