I'm a bit confused or perhaps overthinking something. When we talk aboout ventilation and such we measure the space in cu ft. A space that is 4' x 4' x 6' = 96 cu ft.

Fine

However when we talk about light we talk in sq ft. We shoot for anything in the 3000 - 5000 lumens(?) per SQ FT!!!

Well, cu ft and sq ft are different, right??

So what would the footage number be for the above example in regards to a light formula, a space that is 4' x 4' x 6' ?? Would it be 96 like the other? Or, could it be 16 (4' x 4')?

Or something completely different??
