Cute vintage resistor ballasted fluorescent tube

I can remember buying this from one of the big UK component suppliers, because i was intrigued by a fluorescent tube being run directly from the mains supply with nothing more than three resistors.
The main resistor is for limiting current, and the other two are for limiting current to strike electrodes at each end of the tube.
It's reminiscent of the classic mercury vapour lamp with internal strike resistor.
I'm actually getting deja-vu of another video I made ages ago with a similar tube in a night light. I finally found the video, and it uses a combination of resistor and capacitor as the ballast, but the same four electrode style of tube.

This also keeps the channel independent of RUclips's algorithm quirks, allowing it to be a bit more dangerous and naughty.
