Disinfection with Far-UV (222 nm Ultraviolet light)
An overview of Far-UV (222 nanometer) technology and its disinfection capability. An outcome of the COVID-19 pandemic is an increased need for safe, disinfected public spaces. It is imperative to reduce risk in the commercial aviation industry, which moved one billion people across the globe in 2...Read more -
Germicidal Lamp Technology
Germicidal Lamp Technology When researching UVC Germicidal Fixtures, you may come across several different types of lamp technologies and configurations. All UVC lamps essentially consist of a quartz envelope containing mercury and other gases and electrodes. When the lamp is struck, the energy b...Read more -
The Benefits of UV-C Disinfection
The Benefits of UV-C Disinfection Systems are Numerous, Including: Effective for all types of micro-organisms, including bacteria, viruses, fungi and protozoa No disinfection by-products (DBPs) formed Low capital and operating cost Easy to operate and maintain Safe and environmentally f...Read more -
Is 222nm UV Light safe?
There are many different wavelengths within the broad UV spectrum, each with their own potential application and safety profile. Higher wavelengths like UVA and UVB can be hazardous to your health, but UVC 222nm is safe for occupied indoor spaces ...Read more -
Effectiveness of 222nm Ultraviolet Light on Disinfecting SARS-CoV-2 Surface Contamination
A peer-reviewed study published in the American Journal of Infection Control examined the effectiveness of Far-UV 222 nm against the SARS-CoV-2 (the virus that causes COVID-19) on surfaces. In this study, a modest Far-UV 222 nm dose of 3 mJ/cm2 resulted in a 99.7% reduction in “viable” SARS-CoV-2...Read more -
FIGHTING COVID-19: USING ULTRAVIOLET LIGHT TO DECONTAMINATE CT SCANNERS
CT scans are vital to imaging lung diseases including COVID-19, but disinfecting the machines between use is time consuming. One team of researchers may have landed on a solution. Vanessa Wasta and Sarah Tarney / Published Dec 8 In an effort to streamline medical imaging workflow, researc...Read more -
Type of UV Light Called Far-UVC is Safe to Use Around People and Kills >99.9% of Airborne Coronaviruses: Study
June 25, 2020 — More than 99.9% of seasonal coronaviruses present in airborne droplets were killed when exposed to a particular wavelength of ultraviolet light that is safe to use around humans, a new study at Columbia University Irving Medical Center has found. “Based on our results, con...Read more -
Can UV Light Kill the New Coronavirus?
Ultraviolet (UV) light is a type of radiation. It has more energy than radio waves or visible light but less energy than X-rays or gamma rays. You can be exposed to UV light via natural sunlight or through human-made sources like tanning beds. UV light has been used as a means to kill germs like...Read more -
What is UV and UV-C technology
What is UV? It is often referred to as ultraviolet ‘light,’ but UV is a type of electromagnetic radiation with wavelengths shorter than visible light and longer than X-rays.UV radiation falls into three categories depending on its wavelength: UVA, UVB and UVC. The shorter the wavelength, the mor...Read more -
Kobe University and Ushio Prove 222 nm Far UV-C Light Reduces Bacterial Counts and Causes No Damage on Human Skin
Ultraviolet radiation C (UVC) is defined as 100 – 280 nm wavelengths UV. UVC from solar UV cannot reach the surface of the earth, because this range of UV is absorbed by the ozone layer. Conventional germicidal UVC light (254nm wavelength) can be used to disinfect unoccupied spaces such as...Read more -
What is UV-C Bringing the Power of Sunlight Indoors
What is UV-C Bringing the Power of Sunlight Indoors The UV Spectrum UV-A, UV-B, and UV-C are all part of the ultraviolet light spectrum. UV-A results in skin tanning and is used in medicine to treat certain skin disorders. UV-B has a very high penetrating ability and r...Read more -
UV Lights and Lamps: Ultraviolet-C Radiation, Disinfection, and Coronavirus
Given the current outbreak of Coronavirus Disease 2019 (COVID-19) disease caused by the novel coronavirus SARS-CoV-2, consumers may be interested in purchasing ultraviolet-C (UVC) lamps to disinfect surfaces in the home or similar spaces. The FDA is providing answers to consumers’ questions about...Read more
