Just depends on what your keeping. 200 is minimal imo. 300+ seems to keep colors up pretty well... Considering tank stability among a few other factors. What kind of fixture do you have? 4 t5's on an 18" wide tank for SPS isn't ideal also. You want 6 bulbs minimal.

Lighting is not the only factor for coloring of SPS.
