OSRAM XBO 4000w HS XL OFR metal halide bulb

InOSRAM XBOlamps, a luminous arc is struck between two electrodes in an atmosphere of purexenon gas. Because the gap between the electrodes is only a few millimeters even in high wattage versions, XBO lamps come very close to being an ideal point source of light. XBO lamps offer extremely high light output and a color temperature of approximately 6000K, similar to that of daylight. They provide a continuous spectrum in the visible range and have a near perfect color rendering index. The exceptional lamp-to-lamp color consistency they exhibit when new is maintained over the entire life of the lamp. "XBO" lamps rapidly achieve full lumen output and have hot restrike capability.
