Product Warning

Xenon Short Arc lamps emit harmful ULTRAVIOLET RADIATION, are under HIGH PRESSURE, require a HIGH VOLTAGE ignition, and can GENERATE OZONE. These lamps get VERY HOT during operation, and remain hot after operation for a significant time. Avoid direct or reflected exposure as this can cause serious skin burns and eye injury. This lamp should only be operated in properly designed and maintained equipment. Proper protective gear should be worn at any time the lamps are to be handled.
