I would also agree with sticking with T5s. They give some of the best colors in SPS IMO. Bulb replacent costs are often quoted as a reason to go with LEDs, but led technology is changing so fast that people are replacing pucks, and adding spectrum each year. It's just as costly. If you want full spectrum and high end, the Mitras or hyperions/pandoras are the best. I also like the reefbreeders lights, and have one over my 60cube. It is simple and works great, no software hassles and easy programming.
