If you've never seen neon up close, plasma is such an incredible light source. It's like the light is just floating being emitted from empty space. I took a neon workshop a few years ago, and it became clear why people are still willing to painstakingly make these signs - there is really nothing comparable to them, they're like magic

I love plasma so much, I have multiple “Jr.” globes from Aurora Plasma Design (which have a voltage? adjustment knob), some gas tubes, ancient indicator bulbs from Ukraine/Russia, and an ancient VTG/Rabbit Systems “Eye of the Storm” E-6000 globe from 1987 (which has two adjustment sliders, and a few cheapo globes.

If you are interested in a globe, I’d highly recommend the “Phoenix Rising” Jr. globe they offer. At lower powers it’s near silent, and you can typically adjust them down to have 3-5 small tendrils wafting around each other lazily. APD’s gloves also have thicker glass, and are rated for running all day at below 80% power. At full power my phoenix rising globe uses ~12 watts, and at the lowest power it’s something like 3-4 watts. Unfortunately tariffs, inflation and noble gas cost have hammered the price in the last year.

I definitely prefer silent and lazy looking plasma instead of the frantic screeching storms that most globes have. I uploaded a few example videos here: https://imgur.com/a/bg8fsCW

One thing you can often do is take a cheapo Chinese glove, and use a voltage adjustable power supply and tune it down that way, though I couldn’t tell you if that’s ok for the electronics long term or not.

Another thing to look into if you love plasma, are toroids (donuts).
