I went with the JBJ LED MT-601 89 watt model which is said to be able to support med-high light corals and has comparable PAR to the halides. There were two different models. One was for low - med ligh corals which was the LED MT-603 and the other was the one that I got. I haven't recieved it yet though. The reason I went with the LED set up was that I live in Southern California so it is always pretty warm and I like the 50,000 hours of time (10 years at 10 hours a day) I can put on the LEDs without replacing them not to mention that I would probably have to get a chiller to keep the temps down. I got this set up because it came with a wave maker, protein skimmer, and stand for $699.00.
