I forgot to add that if I had used the watts per gallon rule, I would
have thought I had to put 700+W over this tank when I really only need
about 384W worth of PCs. If we have reflectors like AH Supply sells,
then we can further reduce the amount of light needed. I do not know
what reflector (if any) the old rule of thumb assumed, but I would guess
that it assumed a diffuse reflector like a shop light or white canopy.
If that's the case, then you could produce the same levels of
illumination as 720W of F48/T12 lighting using only about 340W of light
from AH Supply. Instead of costing me $30.61 per month, my lights would
only cost $14.45. Efficiency kicks ass! ;)
