The HPS bulb light spectrum already simulates fall.... If you decrease the intensity of the lamp, that would be the equivalent of going from full sunlight (100%) to partially shaded (75%).... Know what I mean....

Basically, you'll just cut yield by lowering the intensity after you've already run 100% power....
