Your choice on LEDs is:
Expensive computer controlled LED
lights that are very cool, but costly
Chinese panels, cheap, but buyer beware. It is what I use, very successfully, but I have them built to my spec. in China
DIY panels, my son just did this using Cree emitters, pretty impressive but you need some technical proficiency. Cheapest option of all.
Much info on LED
panels on this forum, everybody has a different opinion on the manufacture, but little disagreement that they are a superior way to grow corals.
