Some of the experts say PAR from white doesn't count. Turn your whites to 0%, then check your PAR readings for accurate usable PAR. Whether they're right or not, I have no clue. Whether it's that big of a deal or not, I also have no clue. Are we talking going from 300 to 280? How much of a difference is that going to make?Hmm.... But my lights arent at 0% white.
