Quartz glass is not that expensive in China, an example: https://www.aliexpress.com/item/4000092520926.html?spm=2114.12010612.8148356.55.22ad38dd9RXlr1 . But I guess we want to know if they do use a quartz lens, and what leds are used, partnr or link please and wavelength and radiometric power.
And of course: this will be one dangerous flashlight if really UV-C, for your eyes but also for your skin, causing burns and it is carcinogenic.
Hmmmmmmmmmm, interested as I like to live on the edge…
Interested.
how is this light supposed to be useful to an average blfer here?
Interested, depending on the final details.
Interested.
interested…I guess
This light needs a remote control in my opinion.
Set the light in position,leave the room then turn it on.
That being said,I am interested.

you don’t need safety glasses as UVC does not penetrate all the way to the retina, but anything like skin gets a terrible time being sterilized
good UVC LED like Klaran 50mW costs about 20$ in quantity naybe 10$, then 20$ for the quartz glass window, likely they use a plastic aluminum coated reflector
so looking just on LED and optics we hit 200$
If they go cheap with 3-5mW LEDs there is no purpose using 18 of them if 2 Klaran can do the same output
below 300nm you need quartz glass (fused silica) borosilicate will block UVC
Ask Schott how much B2O3 it contains, it has to be a glass that has almost none in it or it would block UV
such glass composition is called quartz not borosilicate
Borosilicate glass is 80-90% silica(SiO2), the main chemical component in quartz
Interested!
yes interested

Rocks!
UVA in the S2+ UVC makes a lot more things glow
Most of the time yes UVA will glow, I can think of 1 thing that im forgetting the name of that glows in UVA only
I am really interested in it.
I bought decent UVC LED BAR LIGHT for killing germ in mask.
it seems work well.(it reduces bad smell)
