DPI Lightning 45 projector relamping, 3.6 kW xenon lamp, reference 104-578. Relamping of your high-end, high brightness Digital Projection projector Lightning 40 series involves taking your current used lamp house and installing a new xenon lamp. The lamp house is tested, refurbished, and retargeted to ensure maximum light output, then tested again to ensure 100% performance in a projector test bay. This process is accomplished within 48 hours* from the time it reaches our Lab, and costs less than a new lamp house. (*lamps being in stock). Full Factory warranty.
