Scholarly Refereed Publications
Most of my most recent publications have to do with the detailed science of traditional discharge light sources. This science has been rendered mostly irrelevant by the advent of Light Emitting Diodes, LEDs. The LEDs have mostly displaced traditional electric light sources, most notably because they have higher energy efficiency and generally longer operating life. They also offer more color design flexibility, and great electrical control capabilities. While I was involved with LEDs late in my career, I did not do the sort of scientific investigations of them that I had done earlier with the traditional light sources.
