alt Hacker NewsI looked it up and Far-UVC (typically 222 nm) seems safe-ish. But how do you confirm it's not outputting 254 nm or other wavelengths in the UVA/B range? Seems likely to happen with sloppy production of sources. You really have to trust the filter on the light or verify the frequency somehow.

Well, just use your USB spectrometer, of course.
...you do have a USB spectrometer, don't you?
I have mine in my bedside drawer. I use it almost as often as my multimeter.
