Dez also uses 3 and has great results, although he did add supplemental strips to fill in the shadows.

I think 4 units would eliminate shadows but would personally try 3 and then see if the extra cost is needed or not. My tank is only 20" deep so I can't say if raising the lights a couple inches higher and cranking up the intensity to 100% (over time) would give you the effect you are looking for or not. While I'm sure it'll grow coral just fine, beauty is in the eye of the beholder.
