I formerly obtained bulbs from Tony Greer of Texas. He was ill the last time I corresponded several years ago. None of the local sign companies seem to carry those gas tubes anymore. A difficult item to find. Tony filled some of the xenon tubes at 10 torr, which would give a lightening like display when used from a solid state 20 k transformer.
