Today Geisemann announced a new flavor of metal halide bulb known as Megachrome Crystal.  This DE bulb is available in 150 and 250 watt versions, and promises a new spectrum of colors with a pink overtone to accent fluorescent colors in corals.  In addition, Geisemann claims that this bulb is designed to provide consistent output with a lifecycle of over 3 years.  Additional details should be on the Geisemann website shortly.
