This German-made Radium 20000K metal halide bulb offers excellent coloration and intensity for a 20k bulb. It is crisp-white with a strong blue tint. It really brings out the fluorescent pigments in corals. We have been using these bulbs for 4 years. We have tried many bulbs and this is one of three that we really like and use. nicely. Fluorescent supplementation is not necessary unless you want really want to make the coral colors pop! SVHO's give a great simulation to the dawn and dusk imitation. An electronic ballast, magnetic pulse-start ballast or magnetic HQI ballast is required to ignite this bulb. This bulb is white with a blue tint on a magnetic HQI ballast. It will burn more blue on an electronic ballast or pulse-start ballast. An excellent choice for reef tanks up to 24" deep or less.
