I have a cheap UV-C lamp that I purchased from ebay. Aside from the danger to your skin and eyes, after running for a few minutes there will be a distinct ozone smell in the room. Once I keept it on for a few hours in a small room (windows and door closed, no people inside). The ozone smell was still there after one week. So at least the lamp that I own would not be suitable for killing virii in indoor environments, unless there is an easy way to convert the ozone back to O2.
- mensetmanusman 4y agoIf a cheap UV lamp doesn’t have a sub 200 nm absorber layer, it will generate orders of magnitude more ozone than it should: https://www.uvccleaningsystems.com/cm/dpl/downloads/content/1107/Ozone-222nm_lamps.pdf https://www.uvccleaningsystems.com/cm/dpl/downloads/content/... Be wary of cheap electronics. E.g. People have been blinded by green laser pointers that convert 1064 nm IR light because of removed ir blocking filters that certain low cost manufacturers remove out of ignorance.
