Not the same (less safe)
This is incorrent, we've been selling low-cost Far-UVC for quite a bit longer than Aerolamp (they use some of our technology), and it is is proven to be as safe by third-party testing.
Sorry I will correct my post. I agree with you. Far UVC super safe
The spectra are slightly different, but Nukit is also filtered, I would expect it to be just as safe--just lower output
There are lot of fake ones out there. Especially ones with LEDs. Nobody has a 222nm LED with enough power for this yet.
Someone should make a simple tester. Something that's on the end of a stick, you hold it up near the ceiling, and it lights up:
- Green - enough 222nm light to be effective, not too much other UV.
- Red - too much other UV, light is dangerous.
- Yellow - only "homeopathic" levels of 222nm, ineffective.
You can buy NBS-traceable UV meters, and even a spectrometer, but they're expensive.
