there are pro's and cons on each system. IMO, i have not seen LED's to give the same color people are used to off corals and the light in the tank as well. Yes, coral are colorful on the newer LED systems but i would prefer MH over LED's. All the LED systems i have seen look alot like T5's over a tank. colors floresce but they don't have the same look as they do under a good MH bulb. Most people i have heard of or know that have LED's aren't as happy with the LED's vs their MH system before. But they were running the old LED's and not the newer versions which have improved a bit.

Your pretty much paying for the toys that come with the LED's like light cycles and dimming and color changes as well as the lower electric costs and heat. And If i was running a softie/lps tank and had money to blow i would get a LED fixture.

	MH Metal Halide Lighting, typically used for high intensity light demanding corals such as SPS. Bulbs come in varieties of spectrums (7k, 10k,20k), and intensity (175W, 250W, 400W).

	LPS Large Polyped Stony corals – In the aquarium hobby this is a common division of the species of stony corals based upon the visual assessment of the size of the polyps. Corals in this category were among the first stony corals to be kept successfully in captivity and include many very beautiful species. Commonly kept Genera include Euphyllia (hammer/frogspawn coral), Favia (brain coral), Plerogyra (bubble coral), Lobophyllia (meat/tooth coral), and Caulastrea (candycane coral). LPS corals also include the popular solitary non-colonial stony corals such as Fungia (plate coral), Cynarina (button coral), Trachyphyllia (open brain coral), and Herpolitha (tongue coral). Like their SPS counterparts, LPS corals require good water quality, intense lighting of the appropriate spectrum, adequate water movement and regular supplementation of calcium.
