Original Lamp For CHRISTIE DS +26 DS +300 DS +305W DS +305 Projectors This replacement 220W UHP (Ultra High Performance) is a metal halide lamp manufactured by Philips, provided to you by Christie. This lamp is user replaceable (following Christies lamp replacement procedures) and will last up to 3000 hours (low power mode) . The benefits of using a UHP lamp in this Christie projector is that is allows for a smaller and lighter projector (because the power supply is smaller and lighter), a cooler running, quieter, and less expensive-to-operate projector (because of the lower wattage) and a longer lamp life (because the stresses on the lamp are reduced).Please note this item is non-returnable, see our returns policy for more information.
