		Hi, 
 
Its probably better to get a book and look up the lighting requirements in there.  I have tried searching for this stuff on the web, but it's all in the books.  The really expensive books... 
 
In general, 100 to 150 uMol/(M^2*s) is representative of 40 M depths in the ocean -- this is the bare minimum for reef tanks.  LPS and softies reside in this area.  2.5x that (or 250 to 500 uMol/(M^2*s)) for SPS rich areas -- which is around 10M to 15M.
