Amazon.com Product Description This long-life bulb is the right choice for all 9000 series 3M overhead projectors. They're re-engineered for increased efficiency, so you can expect fewer bulb changes than in years past, coupled with plenty of power that ensures clear, crisp images. Many projector models include automatic bulb ejectors, making replacement a snap. For projectors with extra lamp arms, you'll want to make sure they always have a bulb that's ready to go--no pausing in the middle of important presentations. The average life expectancy for each of these bulbs is an impressive 130 hours, and teachers and traveling executives alike will appreciate the power-saving design.
