Maury Wright at LEDs Magazine reports Ultraviolet (UV) radiation in the UV-C band (100–280 nm) will deactivate most viral, bacterial, and fungicidal pathogens given the proper dose. Moreover, the radiometric energy at wavelengths below the human visual range seems more acceptable and easier to deploy than yet more chemical disinfectants. Educational facilities would be a…

Light is an important aspect for human, plant and poultry survival, a piece by Aviagen published in Poultry World this month observes. For animals, the circadian rhythm is facilitated by patterns in light intensity, but the perception of light between humans and poultry differs. Specific wavelengths of light can penetrate the skull of poultry, and…

Never would any of us have hoped for a pandemic to occur just to create a business opportunity for the lighting sector, Maury Wright at LEDs Magazine says. Still, it’s true that COVID-19 has pushed interest in germicidal ultraviolet (UV) technology to incredible heights. UV-C-band radiation (100–280 nm) realized with legacy or LED sources can…

Alicia Kelso at Forbes reports one promising pilot from Yum Brands’ burgeoning Yum Innovation function is a partnership with Columbia University to test the effectiveness and safety of far-UVC light technology to inactivate viruses.The partnership between Yum and the Columbia team led by Dr. David Brenner, director of the Center for Radiological Research at the university’s Vagelos College…

Ultraviolet germicidal irradiation (UVGI) is an effective method that could potentially be used to purify the ambient air in them. However, it cannot be directly used in the presence of humans and, therefore, it is not operationally suitable…

See https://onlinelibrary.wiley.com/doi/pdf/10.1111/php.13387The COVID-19 pandemic has generated great interest in reviving an old intervention technology, particularly for air disinfection – ultraviolet germicidal irradiation (UVGI). Since UVGI was developed and refined more than 80-90 years ago, the ultraviolet source of choice has been almost exclusively the low-pressure mercury vapor discharge lamp. Today, with new lamp technologies, there…
