These are all electrode-less gas tubes powered from a high voltage high frequency transformer. I can vary the voltage form 0 to about 20kV at about 20khz. Over the range there can be quite a few changes in the discharge. The copper foil on the tubes is to protect from hot arcs that form at the wires ends and can quickly puncture the tube.

Westinghouse OV-25s at sunset.
Good quality things are awesome. Cheaply made things are not.
Pretty, please no more Chinese failure.
