How many Lumens does it take for all corals to grow 12 inch depth

I am looking at the Marineland double bright fixtures for the frag tank. Does anyone have any experience with them

or am I heading the wrong direction here

I have 48~3w crees on my 72 bowfront and can't turn it up past 15% without blindin my foxface and bleaching my frogspawn. I believe my depth is 18". I could be wrong on that
