Cold Water Aquarium Fish

They also produce much less heat than metal halide lamps.

There is no question that metal halide lighting is still (and probably always will be) the mainstay of marine reef aquarium lighting. However, we have rarely seen a reef aquarium lit by metal halide bulbs that did not require a chiller for success, unless the aquarium was located in a cool room or was equipped with some form of major ventilation system. PowerCompact bulbs allow many photo-receptive species to be kept without the intense heat produced by halides. Research has shown that many stony corals, clams, and other sessile species that depend on photosynthesis of zooanthellic al
