From a lot of this new research coming out along with the UV-C sterilization uses in the past we can be confident that the SARS-CoV-2 coronavirus can be inactivated by UV-C LED exposure. Even if future evidence proves this, please remember the following factors that will determine the dosage of your UV-C LED source and the overall success.
Power of Light – need enough power to be able to effect pathogens and not be absorbed before reaching target.
Angle or Focus of the UV-C LED – is the light angled toward target? Some experimenting with UV-C applications are realizing that optics to focus the powerful UV-C LEDs are needed to be the most efficient.
Distance – How close in proximity do you need to sterilize the intended area?
Exposure Time – how long does it need to sterilize an area?
When developing or buying a UV-C sterilization product you want to be 100% certain on the accuracy of the specifications. As we have shown in this post, UV-C sterilization needs very specific wavelengths and power, so please do your homework before trusting a UV-C product. This is especially important in the case of sterilizing against COVID-19 as there is no way to validate some of the claims instantly. An incorrect claim could put others or yourself at risk.
