Ellipitical metal halide lamps fall into three main categories. Those that run on son gear, those that run on mercury gear, and those that run on mercury gear with low pulse ignitors, but there is a fourth and they are lamps with internal ignitors designed to replace mercury lamps (MBF/U). Some lamps will run on both gear, but these tend to be less efficient that dedicated lamps.
