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.
The gas purity is not great but the set-up is:
1. Ne low pressure
2. Ne/Ar low pressure
3. 2. At different voltage
4. Ne at slightly higher pressure
5. Ar/I - made this a halide tube with Iodine seen on the tube wall
6. Air with some fluorescent lamp powder

Very nice!

Good quality things are awesome. Cheaply made things are not.

Thank you for sharing these unique discharge lamps

Pretty, please no more Chinese failure.
