750 Watt Equivalent 5500k CFL

Ray,

I understand your statements about the CFL's being inefficient and that the plants receive roughly a third of the emitted light. But, how about FC measurements taken at the plant levels? Is it equal to the reading the light measure is giving me or is it lower? I just started using artificial lighting (CFL's), recently, and I've been wondering about that.
