LumenFocus’s new UVFocus line of germicidal UV luminaires use UVC or near-UV technology to disinfect surfaces within line of sight of viruses and bacteria.
Currently, LumenFocus is offering three UVC luminaires: the GUA S, the GUA P, and the GCD. The company stated in a press release, “When used correctly, these antiviral and antibacterial products will help mitigate the risk of COVID-19 infection.”
The GUA series of upper air germicidal fixtures includes a pendant-mount option (GUA P) and a sconce (GUA S), suitable for applications such as lobbies, hallways, offices, bathrooms, conference rooms, hotels, and retail settings. When these luminaires are mounted at the specific height of 7 feet, the 254nm 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 luminaire when motion is detected in the irradiation zone.
The luminaires utilize low-wattage, ozone-free GUVT8 lamps that reduce airborne pathogens. For safety, a red light indicates power to the ballast, and a green light indicates the lamp is running.
The housing of the GUA is constructed of durable cold rolled steel, with a silver (standard), white or black powder coat finish. A stainless steel housing is optional. The polished aluminum reflector is optimized for the dispersion of UVC light. The GUA P is available in a 4-foot length option, while the GUA S comes in 2- or 4-foot lengths.
The GCD is a wall-mounted direct luminaire for providing pathogen eradication in unoccupied rooms. It hangs in the corner, where the wall meets the ceiling. The GCD comes in 1- or 2-lamp options, utilizing the same 254nm GUVT8 lamps that are in the GUAs. For safety, a reverse occupancy sensor powers off the unit when a person is detected in the occupancy zone. The unit powers back on once the area is unoccupied again. Like the GUAs, the GCD utilizes red and green indicator LEDs to indicate whether the ballast has power and the lamp is energized.
The GCD is also constructed of cold rolled steel in silver (standard), white, or black powder coat finish, with the stainless steel housing optional. Like the GUA, it utilizes a polished aluminum reflector specially engineered to disperse UVC light.
The electronic ballasts in the GUAs and the GCD are specifically matched to the lamps for optimal performance and lifetime. These luminaires are UL 1598 listed for US and Canada and certified IEC 62471. They come with a 3-year warranty (except for the lamps, which are covered under the manufacturer’s warranty).
