Mercury Short Arc lamps emit harmful ULTRAVIOLET RADIATION, are under HIGH PRESSURE, require a HIGH VOLTAGE ignition, and can GENERATE OZONE (unless designated "OFR".) 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.
