Here is my PAR reading from my CFLs to my screen.

226 at 4" and 302 at 3"

Used my fish net to push my hanging light an inch closer.


FYI I did push the screen back to account for the 1" sensor width.

Bulbs are two months old.

I hang them horizontally which creates a more even light coverage. This corrects "hot spots" on algae screens when the CFL is pointed at the screen. Unfortunately or fortunately (depends how you look at it.) this puts 100+ PAR in my sump which has created wonderful place for mysis, pods and worms live undisturbed.
