Germicidal lamps are designed to destroy viruses and bacteria using ultraviolet light. But not just any UV light will work, and I came across an example of a lamp that was advertised as germicidal but ...

The COVID-19 pandemic has increased the public’s awareness of UV disinfection, and that’s reflected in the growing number of LED-based products available on the market. UV light is used to disinfect ...

LEDs emitting light in the range of 200 nm to 400 nm are classified as UV LEDs. Within this range, there are three bands, UV-A with wavelengths from 300 nm to 400 nm, UV-B with wavelengths between 280 ...

Many efforts to reduce transmission of diseases like Covid-19 and the flu have focused on measures such as masking and isolation, but another useful approach is reducing the load of airborne pathogens ...

How ultraviolet light (UV) works as a disinfection technology depends upon the wavelength(s) being employed. The UVC band with a wavelength of 200-280nm has emerged as a viable solution for interior ...

Chipmaker raises power performance for killing germs in drinking water. Columbia, SC, USA – September 18, 2010 – In an ongoing development program to increase the power of ultraviolet light emitting ...

The same light bulbs used in offices and public spaces can destroy coronaviruses and HIV, according to a new study. The same light bulbs used in offices and public spaces can destroy coronaviruses and ...

Hospital infection rates are on the rise with 1 in 20 Americans already being admitted to the hospital this year, according to CDC estimates, and in some instances, winding up more sick than when they ...

Scientists demonstrate the first direct germicidal effect with an ultraviolet LED source. A US collaboration has reduced levels of E.coli. bacteria in water by over five orders of magnitude using 280 ...

Perhaps the first randomized trial of an air cleaning device for nursing homes showed no significant impact on the primary endpoint for acute respiratory infection incidence. A secondary analysis did, ...

While useful for killing pathogens including SARS-CoV-2, 222-nanometer UV lights may produce harmful compounds in indoor spaces, and should be used with ventilation, researchers have found. Many ...
