Description


Germicidal UVC Light Bulbs
Ultraviolet germicidal light bulbs are widely used as an air, surface, and water sanitizer. UV germicidal light destroys the ability of bacteria, viruses and other pathogens to multiply by deactivating their reproductive capabilities. Germicidal light includes the UV-C portion of the ultraviolet spectrum with wavelengths between 100nm and 280nm. The target wavelength for optimal germicidal light bulb effectiveness is 253.7nm which defines the germicidal category. For water sanitation, ultraviolet germicidal lamps also emit ozone at 185nm.
Warning: UVGI radiation is extremely harmful to skin and eyes.

What is the UVC dose for killing or disabling the COVID-19 virus?
Because the COVID-19 virus (SARS-CoV-2) is so new, the scientific community doesn't yet have a specific deactivation dosage. However, we know the dosage values for comparable viruses in the same SARS virus family are 10-20 mJ/cm2 using direct UVC light at a wavelength of 254nm; this dosage will achieve 99.9% disinfection (i.e., inactivation) under controlled lab conditions. In real-life, the virus is often hidden or shaded from direct UVC light, reducing UVC's effectiveness. To compensate, researchers are applying dosages of 1,000 - 3,000 mJ/cm2 to ensure 99.9% deactivation, the current CDC disinfection goal.
