| Mercury-Xenon short arc lamps are dosed with an exact amount of mercury and xenon gas. As the initial arc is struck by the xenon gas, the voltage will increase as the mercury vaporizes. Normally, several minutes are required for a mercury-xenon short arc lamp to reach maximum operating voltage and output. |

 | The mercury-xenon spectrum, due to the high operating pressure, shows only traces of the xenon gas spectrum. The four main mercury lines dominate the spectrum. Designed to operate in a vertical position, Our mercury-xenon short arc lamps are manufactured in power levels ranging from 200 to 5000 watts. Depending on the lamp wattage, the luminous efficacy ranges from 22 to 55 lumens per watt. |  |
