This absolutely depends on the frequency of UVC and the intensity of the lamp. The lamps this post links such as https://aerolamp.net https://aerolamp.net are putting out 222-nm, which is much safer than longer UVC wavelengths and the intensity is well under TLV when placed 8.5ft up (or higher).

- the8472 9mo agoAh nice, their data sheet has a spectrum. Kind of odd that they don't market the "we filter out the harmful parts" feature more prominently.
- Nukit 9mo agoMany manufacturers refuse to post third party spectral assays detailing safety and power output, it's a big problem.
- vbelenky 9mo agoKinda like advertising "Asbestos-Free Cereal" isn't it? If someone was marketing a product to me and they were super insistent about how super duper safe it was I would probably start getting suspicious
- the8472 9mo agoUV rightfully raises concerns about skin damage, highlighting that they're careful about excluding the harmful parts would be helpful for customers who either know just enough to think "UV bad" or to those who wonder how narrow their filters are. Imo a better analogy would be selling a circular saw with a safety mechanism and hiding the latter in the specsheet.
- gs17 9mo agoNo, it's more like advertising asbestos-free talc.
- trashface 9mo agoThey can leak into higher wavelengths. You are really putting a whole lot of trust in manufacturers if you are sitting underneath one of these for decades with unprotected eyes. Not a risk I would take personally (I have glaucoma already, so I'm a bit more sensitive than the average person about eye health)
