IMHO, the watts/gallon rule rarely applies.

Nope, doesn't apply here very well either.

We have 4 40w (48") bulbs using old fashioned tar ballasts over our 100
gallon (60"x18"x20"tall) tanks. However, we prefer to maximize the lumens
per watt (and $ per watt :-), so we use two Triton bulbs and two Penn-Plax
Ultra Tri-Lux bulbs over each tank. Nice and bright, good color rendition
and they photograph well (all the photos in our web site were taken with
normal tank lighting and plain old daylight film).
That's 1.6 watts per gallon, but they're good watts.
