Some high intensity LED torches and garden solar lights have a
chopper circuit that supplies the LEDs with a high frequency DC
much higher than the LED would normally operate on.
Maybe a similar circuit could be modified a bit to excite a neon.
On my bench power supply none of the various neons I had would
glow until about 40v or higher.
Interesting stuff. Thanks for the SC link Merlin.
