I would go T5's over any of these for a mixed reef 65 gallon. I'm a big fan of T5's for dialing your personal preferences in regards to color temperature. If you must choose between LED's and MH I would go MH all day long. The reason? MH is proven and effective and 150's won't add much heat at all to a tank provided they are hung from a reasonable distance. I've seen far too many LED tank owners go back to T5's or MH. I just don't think we've really gained the necessary knowledge to effectively use LED's on a broad consumer basis without a large percentage of people detrimentally effecting corals.
