Metal Halide Aquarium Light Fixtures
There is no other practical lighting source for an aquarium that will provide as much light intensity as metal halide aquarium lighting. This is why metal halide lighting systems are popular among reef keepers where light intensity is crucial for the survival of reef organisms. The need for light intensity provided by metal halides is even more important in deeper tanks. Metal halide lighting is practical for aquariums deeper than 16" and become a necessity for aquariums deeper than 30".
