Tungsten-barium-xenon lamp is a tubular quartz bulb filled with a proper amount of high-purity xenon gas, and the two ends are sealed with barium tungsten electrodes with a pole distance greater than 100MM. There are two types of long arc xenon lamps: natural cooling and water cooling. Natural cooling xenon lamps are generally filled with (2.66~26.6))×102pa xenon gas, and water-cooled xenon lamps are filled with (1.33~5.32)×104pa xenon gas. The color temperature is 5500~6000K, the power can be from 102~2×106KW, and the luminous efficiency is 24~37lm/w. The luminous efficiency of water-cooled long arc xenon lamps can reach 60lm/W, and the general life span is 3000h. The power of long arc xenon lamps can be very large, and the volt-ampere characteristic has a positive resistance characteristic, so only the starting device needs to be installed. Its specifications are with ballast and without ballast.
