Interesting read, thanks. Someone I know got one to boost Vit D levels, shame the article didn't touch on that. Starting to wonder if it works for that.
Correct. Vit D levels in people can be boosted by UV-B. https://www.sciencelearn.org.nz/resources/1313-vitamin-d-and-uv
Blacklight is of a different wavelength outside the direct visible spectrum and can be used for all kinds of purposes to make hidden things visible. for instance blood on objects only superficially wiped, biological remains of pee and poop in toilets and on the walls.
In disco's you can have this strange effect of blacklight where it only illuminates white clothing.
