4-4. Lamp Theory
The MP8670/8745 with a DC 260 watt metal halide bulb is capable of producing 550+ lumens of
uniform brightness across the entire projection image.
The metal halide bulbs should never be touched. When oil from your skin touches the bulb, it provides a
focal point for the lamp energy. The lamp burns hotter at that location and eventually burns through the
bulb prematurely.
