K. 3000 SHORT-ARC TYPE METAL HALIDE LAMP 575W L5431 LONG LIFE MECHANISM HAMAMATSU has developed a unique technology (PATENT PENDING), called as double halogen cycle, which extends the average lamp life over 3000 hours. QUARTZ GLASS UNIQUE “DOUBLE HALOGEN CYCLE” TECHNIQUE ARC Outer gas convection suppresses the thermal reaction with the fused silica envelope thus protect it from crystallization. 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.
