Lamp Compatibility Information:
Mitsubishi DLP® and LCD projectors have been manufactured to strict specifications and are designed for use with genuine Mitsubishi replacement parts for optimal performance. The lamps used in Mitsubishi DLP® and LCD projectors are critical parts. The factory-provided lamps were specifically designed to meet certain performance, quality, and design specifications. Non-Mitsubishi lamps may not meet those same standards, may not be compatible with your projector model, and/or may not be as reliable and durable as Mitsubishi lamps, all of which may negatively impact the performance and operation of your projector.
