The below paper suggests that with approx 2.4mWsec/cm2 it's possible to inactivate 99% of viruses. No specific mention of coronavirus, but could we use 13W aquarium UV lamps (are they UVC?) for an effective solution?<p>https://www.researchgate.net/profile/Chun_Chieh_Tseng/publication/239392662_Inactivation_of_Virus-Containing_Aerosols_by_Ultraviolet_Germicidal_Irradiation/links/54f823b80cf2ccffe9dce501/Inactivation-of-Virus-Containing-Aerosols-by-Ultraviolet-Germicidal-Irradiation.pdf
What's the usage idea?<p>UV sterilizers do work on most all viruses from what I understand but the issue is the the further from the light source the less effective it becomes and time, temperature and humidity are all factors which can affect the effectiveness. A UV-C light strong enough to clean a 100 sq ft room would be dangerous to humans so it could only be used as a sanitary item and not on all the time. At least as far as I understand it.<p>edit: just saw your usage idea. Not sure it would be doable and safe for humans but packages seems totally fair game.
the overhead lamps are not what you want, you want the bulb for the UV sterilizer that is normally used for UVirradiation of water circulating through a manifold.<p>you dont want to use this as normal illumination, it is damaging to the eyes.<p>there is a system where microbiological labs are under constant intense illumination with UV while they are unoccupied. you would be doing something similar i suppose?<p>have look here as an example of what you would need to do a proper job:<p><a href="https://www.light-sources.com/solutions/germicidal-uvc-lamps/uv-light-applications/uv-light-sterilization/" rel="nofollow">https://www.light-sources.com/solutions/germicidal-uvc-lamps...</a><p><a href="https://www.light-sources.com/solutions/germicidal-uvc-lamps/uv-germicidal-lamps/low-pressure-mercury-lamps/high-output-quartz/" rel="nofollow">https://www.light-sources.com/solutions/germicidal-uvc-lamps...</a>
