HAMAMATSU TECHNOLOGY Double halogen cycle convection will supress the dissipation of the electrodes. CONVENTIONAL LAMP SHORT-ARC TYPE METAL HALIDE LAMP 575W L5431 Long Life / 3000 hours
FEATURES
The Short-Arc Metal Halide Lamp, L5431, suited for the light source for projector, has achieved the average life time of 3000 hours. It will enhance the performance of LCD projector and over-head projector (OHP).

It maintains the envelope strength and light transmission even after 500 hours of operation. Inner gas convection assures the metal halogen cycle which minimize the electrode dissipation. 135–5 25.0–0.5 115.0–0.2 7.0–0.5 10.0–0.2 21.0–0.5
