HDM™ reduces active pathogens* on non-porous surfaces using Ushio Care222® far-UVC disinfection** technology. HDM features a mercury-free far-UVC excimer lamp that contains a patented short pass filter for narrow band 222nm emission. This removes wavelengths that penetrate the living tissue in skin or beyond the tear layer in eyes***. HDM surface fixtures are available with 5 inch and 9 inch body heights. Canopy options include recessed or surface J-box mount, and surface J-box mount with a conduit cover. Available in black, bronze, silver and white finishes. Discreet form factor seamlessly integrates into spaces and is ideal for bathrooms, counter tops and other continual-use areas. UV source emits a soft violet glow from a 1.75" x 2.25" opening when powered. LED status indicator visible from room. UV module serviceable from below. * Refer to product specification sheets at acuitybrands.com/UV-Products for efficacy claims and claim substantiation regarding specific products and pathogens **All references to “disinfection” are referring generally to the reduction of pathogenic bioburden and are not intended to refer to any specific definition of the term as may be used for other purposes by the U.S. Food and Drug Administration or the U.S. Environmental Protection Agency. Reduction of the pathogenic bioburden is a function of fixture run time and the distance to the UV light source, airflow, room size, shadow areas and/or other factors, and the level of reduction will vary within a specific space.
