Thanks to James for pointing this nice demonstration out. This arc tube has just cooled enough to have stopped emitting. Still with a high internal pressure, but not excited, it is now absorbing the spectrum it had been emitting. It fades to a light blue before disappearing quickly as it cools. Unlike the low pressure lamp this is noticible under white light.
