@Laberpferd @cmdrmoto Okay, then I do need to take a look at said #SafetyDataSheet - as stated before...

Certifications in that regard OFC change things...

• And I mean like from the lab that certified them and not some CE papers the manufacturer can write and sign off themselves...

Cuz it's one thing if I want a lamp to sterilize water in a fishtank loop or #retrobrite computer parts vs. being exposed to it directly.

@cmdrmoto granted, I have setup some UVC lamp in fishtank water system ages ago because that stuff can actually kill a lot of stuff in the loop and that stuff had all kinds of safety warnings, including the exlicit demand to never ever run it dry or use the light outside it's casing as it can permanently blind.one within seconds.

• Granted this was a professional water treatment component and not something consumers are supposed to get their hands on.

However I know that UVC lights with remotes are used for whole-room sterilization systems in like BSL2 and above labs after pressure-washing surfaces with Steam and wiping down everything with 1-Propanol.

• If in doubt, read the #SafetyDatasheet and stay away from stuff that doesn't come with one - or any #SpecSheet - because w/o professional gear one cannot distinguish a pseudo-white / cold-white blue-is GaAs LED without the yellow photsporous element and real UVC lamps visible emissions.

Unlike say IR where 850nm is faintly red and bright purple on most cameras and 940nm really takes spechal "noIR" unfiltered & Nightvision cameras...
