Oh yeah, I forgot odor eliminating fluorescents too.

Wherever the light shines, you'll want a reflector aiming it toward the plants. They're like $2.
Opie Yutts Reviewed by Opie Yutts on . CFL Light Intensity Question... Does anyone know the optimum positioning of a CFL. What I mean is, does a CFL's light intensity radiate parallel to the bulb (inline with the coil) or perpendicular to the coil. I don't know exactly how to explain my question, but I do not know if I should align my bulbs so that they point at my plants, downward vertically, or if they should be aligned so that they point outward, horizontally. Does anyone know ? Rating: 5
