Acuity Brands Filtered Far-UVC Module with Ushio Care222 Technology is the First to be UL Certified
“This tremendous technical achievement has come at a time when the worldwide awareness of the need to control pathogens has never been greater. Substantive pathogen control in spaces while people are present can support vital activities where we work, live and play,” said
The UL Recognized Component certification paves the way for incorporating the module into a variety of Acuity Brands LED lighting products to deliver a measured 222nm far-UVC dosage in occupied spaces. These lighting products provide a 222nm far-UVC dosage that can effectively target pathogens1 throughout the day in indoor applications such as schools, hospitals, manufacturing, hospitality and retail, while maintaining a natural-looking light emittance.
“The certification of the Care222 module for use in lighting products in occupied spaces is the result of rigorous testing and evaluation performed by UL scientists working together with research and development teams from
An important part of the Care222 far-UVC module development involved the creation of patent-pending dosing electronics by Acuity Brands. These electronics allow for highly precise administration of UVC doses to target pathogens1 in occupied or unoccupied spaces. The completed module is an outgrowth of the 2020 strategic alliance agreement between Acuity Brands and
Ushio’s disinfection technology uses filtered excimer lamps to generate 222nm far-UVC light. The mercury-free Care222 excimer lamps feature a specially designed short pass filter, based on groundbreaking research and technology developed by
Results from laboratory testing and clinical studies suggest that the filtered UV light emitted from the Care222 lamp can reduce known viruses and other pathogens, including SARS-CoV-22, on surfaces and in air. When used within appropriate parameters, the 222nm wavelength emitted from the Care222 lamp inactivates viruses and bacteria at energy levels that do not penetrate living tissue in skin or beyond the tear layer in eyes, allowing spaces in which the lamps are used to remain occupied during use. In contrast, possible acute and chronic damage to eyes and skin may result from the more generally employed 254nm UV wavelength used in many germicidal lamps unless this UV wavelength is used under conditions that sharply limit human exposure.
“Using luminaires as a delivery system allows facilities to take advantage of locations where power is already distributed,” said Schimmelpfenning. “This enables the Care222 far-UVC disinfection technology to be added as a layer of functionality to necessary illumination using the intelligent control capabilities built into the luminaire.”
Acuity Brands is in the process of seamlessly incorporating the Care222 far-UVC disinfection modules in familiar luminaires and stand-alone products from its multiple lighting brands, creating a broad lineup of UL Certified far-UVC-enabled luminaires. Orders are being accepted now for the HDM™ luminaire from Healthcare Lighting® and HLDM™ luminaire from Holophane®. Coming soon are far-UVC-enabled luminaires from Gotham®, Lithonia Lighting® and Mark Architectural Lighting™.
