Germicidal Upper Air Sconce

    The GUA S is a wall-mounted sconce designed for upper air germicidal irradiation. These fixtures utilize low-wattage, ozone-free GUVT8 lamps that reduce airborne pathogens using 254nm UVC. When mounted at the specified height, the UVC light will cleanse the upper air in the room and will not come into contact with humans or animals. A proximity detection sensor comes standard with each GUA. This sensor turns off the fixture when motion is detected in the irradiation zone. For safety, a red light indicates power to the ballast, and a green light indicates the lamp is running. The green light will go out if the lamp fails. The electronic ballast is specifically matched to the lamps for optimal performance and lifetime. A pendant mount version is also available - the GUA P. The GUA S is part of the UVFocus product line of pathogen eradicating luminaires.
    Note: UVFocus products are designed utilizing proven germicidal and antibacterial technology. UVC 254nm products work to deactivate most common viruses (as well as bacteria, molds and yeasts), and 405nm near-UV products are shown to substantially reduce bacterial presence. While these products can be considered disinfecting products, they should be used in conjunction with standard, proper disinfecting cleaning procedures to have the greatest impact for maintaining a clean environment. Successful UV disinfection requires a systems approach taking into account dose, optics and safety relevant to the specific application. Please consult with factory any questions or concerns.
