I think you might have watts, lumens, and PAR confused a bit. Corals really care about PAR. Halides on a good reflector are going to put out the best PAR closely followed or even equal to are T5, then VHO, then PC etc.. All depends on how many lamps you run and the wattage of course. Here's what I would do.... I would come up with a list of the corals you want to keep first, then we can help you with your lighting needs. Softies don't require near the light of SPS and so on. Start there and let us know.
