Abstract :
The devitrification problem of capillary high pressure mercury lamps is shown to be caused by impurities in the natural quartz. It is shown that this problem may be solved by using synthetic quartz of low OH-content. An improvement of lamp life by an order of magnitude appears to be possible.
