Wow

The lamp design, is very similar to the sulfur lamp, but with induction coils rather than magnetron and without rotating the lamp above its axis at high speed.

I never see something like that or something similar

Me too Alex, warning to all only view behind glass or pop a jam jar over it, UV bad for skin and eyes glass is a block to UV

What a remarkable thing! I wonder why they chose the RF operation method instead of a miniature electrode-based low pressure mercury lamp. Perhaps it was for increased lifetime - the normal Germicidal lamps do not have an especially long life.

@James: It comes from USSR time, so I do not expect the primary designed use was anything consumer, but rather something more of a military nature (analytical instruments).

It was quite a common practice to disguise military devices as some consumer things - good example is a chipset "advertised" a BW TV camera sensor chips set, where making real TV camera out of it was the heck complicated, but using it for a sensor tracking black peck on a white surface (or white spec on a black surface) was pretty simple circuit around the main CCD chip given the interface specs (and guess what you need for any optical or IR x-to-air missile guidance system).

So my guess is, the primary use was to have a generic device (common platform) for use with wide variety of radiating elements (for different wavelengths or their combination), where many of them are pretty aggressive towards any metal, the mercury UV capsules were just one of them.

LOL.
FOTON simply was a cosmetic device for disinfection the skin after shaving And lamp in this device was specially designed for him.
Of course, it wasn't used for the main purpose, but was very-very usable for erasing UV-EEPROM chips
