Say I have 1 55w PC light
and I have a 12" tall 20 gallon tank with a small coral cluster directly in the middle of the tank
and I have a 12" tall 40 gallon tank with a small coral cluster directly in the middle of the tank
since the distance between the light and the corals is the same on each tank, isn't the light intensity on the corals the same in each tank?
If so, isn't the distance of the light to the corals much more important than watts per gallon?
