Neat little cold cathode driver
Added 2023-04-15 04:22:14 +0000 UTCYet another UVC video (sorry!). I've got a bug at the moment, so I probably sound a bit husky in this video.
The most notable thing about this set is the small inverter that can also drive short neon or argon/mercury tubes.
The actual UVC tube seems nicely made, and rather disturbingly there's a picture on the listing of a massive pile of them being hand tested by a Chinese operative. I'd presume that area of the factory must be very sterile.
I have tested the power supply with a short neon and mercury tube (12"/300mm) and it worked well, so maybe good for a discharge tube display.

Thanks for the video and the circuit explanation. I bought some to sterilise opacke drinking flasks after longer use. Yust hanging the tube in it and let it burn for a few minutes.
