Reefbrite is good at illumination, not color rendering. A more "daylight" light is good at color rendition in the actual coral, but are not always good at illuminating them. It is a rare light that can do both.
Do your coral have good color and you want to "spice them up", or are the corals themselves dull? Reefbrite can spice up otherwise well colored corals. If your corals are dull, then Reefbrite is probably not your answer, but I have no idea what to suggest without knowing what you keep and how you are lighting stuff now.
