I can't remember whether I posted to this group or to taopa, but, a few
months ago, I did an analysis of the lighting used by Takashi Amano in the
tanks shown in his 3 vol. series, Nature Aquarium World.  It turns out
that, probably by intuition and experience rather than calculation, the
lighting he uses is nearly proportional to the square root of the volume.
So, that's at least one "formula."  Here's a link to the results:

At the bottom of the page, there's a further link to "Lighting in the
Aquaria of Takashi Amano."
