275W NSHA Lamp
The Christie 003-120531-01 replacement 275W NSHA mercury arc lamp is user replaceable and will last up to 2000 hours (typical life) and 3000 hours (Eco mode).
The benefit of using an NSHA lamp in the Christie LX505 projector is that it allows for a cooler running, quieter, and less expensive-to-operate projector. Having lower wattage allows for a longer lamp life.
