The GLO UV-C disinfection upper-room fixtures series now includes two new open-style luminaries designed to irradiate and inactivate airborne pathogens in occupied spaces with high ceilings. The product directs UV energy upward and outward to create an intense zone of ultraviolet germicidal irradiation or UV-C in the upper air. At the same time, occupants can safely go about their business in the lower portion of a room.
