Excerpt: This is an OEM (Original Equipment Manufacturer)lamp and so is a perfect replacement. Replacement is easy. You only need a cross head screwdriver. These lamps get VERY hot so let the projector cool down for at least an hour. Turn the projector over and place on a soft surface (a hand towel or similar) so as not to scratch the case. There is one small cross-head screw visible along one edge of the lamp house door.
