Temperature profiles of the electrodes of single-ended metal halide discharge lamps

The temperature profiles of electrodes in discharge lamps are important as they radically affect the fundamental chemical and physical transport processes within the lamp which have a direct influence on many important factors of lamp performance such as life, efficiency and lumen maintenance. In the past a number of investigations have been made into various aspects of electrode performance and, in particular, their temperature profiles but none have looked specifically at single ended discharge lamps.
