Western Quartz recommends an operating ultraviolet (UV) lamp wall temperature range between 650° C and 750° C.  Higher temperatures can cause devitrification and/or distortion of the quartz envelope resulting in short lamp life. Temperatures below 650° C can cause condensation of the mercury resulting in an unstable environment and premature darkening of the lamp body.  The end seals have a temperature limitation starting at 250° C and above as molybdenum starts to burn at this temperature and higher. Temperatures higher than this can result in oxidation of the molybdenum with subsequent seal failures.
