Default how much lumens per sq. ft.

Hey Ron, I asked you the other day about indoor lighting and lumens per sq. ft. I guess I meant, what is the absolute point of diminished returns with regards to the lumens used by a (light-loving!) plant. Given that all other growth factors are optimum like co2,food,etc. It's just hypothetical anyways, I dont have the $$$$$$ for a dozen 1500 watters! Realistically though, I think like 100-125watts per ft. would have fairly good results. Sorry to babble, thanx for your time and a kick-ass website!
