Stanley Electric Proves 99.9% Inactivation of SARS-CoV-2 for 265 nm UV-C LED in Mass Production
Stanley Electric Co., Ltd. announced that their recently released 265 nm UV-C LED is in mass production and its effectivity to fight SARS-CoV-2 has been tested in cooperation with the Yamaguchi-University by Dr. Daisuke Hayasaka and Dr. Hiroshi Shimoda. As a result of the conducted evaluation…

Summary of test result:
Virus evaluated:
• SARS-CoV-2
Method:
• 10 ml of virus solutions (5 x 10⁵ PFU/ml) in dishes were irradiated with
265 nm UVC LED at different time points.
• Infectious virus titers were determined by plaque assay on cells.
Test result:
• Inactivation rate of SARS-CoV-2 is 99.9% or more, when the UV Dose
is 5.1 mJ/cm2
Stanley Electric is aiming to use this 265 nm UVC LED for various applications, such as surface sterilization, air sterilization, and water disinfection for providing safe drinking water, to control infection against SARS-CoV-2. Please note that we will continue to verify the superiority of this wavelength, by conducting further evaluation tests with different wavelengths of UVC light sources. We will inform you of the verification result once the test is completed.
