    Light Calculator questionable?

    In my 75 gal set up, I have 3 - 48" LED strip lights with a total of 265 diodes, 112 Watt , and 13416 Lumen. Using the light calculator in http://www.rotalabutterfly.com/light-calculator.php, I came up with 204 PAR at substrate level, which will put my light in extremely high light regime...
