I don't think that Putin fears Clinton, but I think that Putin is somewhat enamored with Trump. Trump has already praised Putin's politics, and Putin is probably pretty bitter with Obama for the past eight years, and likely sees that bad relationship continuing under Clinton since she was his Secretary of State.
Kind of funny, our company is on the cutting edge actually, but in fluorescents, not LEDs, which are terrible for producing what we would consider high output of UVB or UVA. There is a huge difference between 320nm and 399nm, yet both are "UVA". 320nm has a lot more energy, and as you up in frequency (down in nm), it forms a Bell curve and gets exponentially more damaging. It also goes down in penetration, which is why you can get a quick flash burn from UVC (100nm-280nm) that doesn't penetrate more than a few layers of skin, but it is very damaging to those layers. And of course, the real kicker is how much you are getting.
And the reason it has that warning on it is simple: anything with any measurable amount of UVA must have that warning by law. The FDA regulates this (CFR 1040.20 for sunlamps, for example). I'm used to seeing them regularly for inspections. For some reason, general lighting fluorescents are excepted from this warning, even though they do produce a measurable amount of UVA.
385nm is invisible to almost all humans, being on the long-ish wavelength of UV, and I wouldn't really say it was very damaging. Everyone likes to jump on the bandwagon like they actually know something about UV when in fact they don't. I've worked with it over 25 years, still do. Out of the millions of products sold, I've never had an injury reported. People do get hurt with UV, but that is exceedingly rare and usually because they didn't follow directions or did something really stupid.
Inside fiber, it is pretty harmless. Most plastics block it (excepting OP4 acrylic), the vast majority of paints absorb it and won't reflect it. It has a smaller wavelength, thus more waves per centimeter, ie: more data. I'm not saying their plan is good or bad, but blanket calling UV dangerous and not workable is ignorant.
