COVID-19 changed the landscape in many ways. Society had to change in many ways because of the pandemic, but that unfortunate situation has also given us a new perspective. Lighting technology can be used in ways besides just illuminating a space. The new UVFocus product line from LumenFocus features luminaires designed for pathogen eradication. These products utilize UVC or near-UV technology. You can click on an image above to navigate to the product page, or scroll down to read a little more about each of these products.
According to the International Ultraviolet Association, along with research conducted by Signify and the National Emerging Infectious Diseases Laboratories at Boston University, UV technology can play a role in reducing the transmission of harmful pathogens, including SARS-CoV-2. UV is a disinfectant for air, water and surfaces. This technology has been used for many years now. Our UVFocus product line includes UVC products - the GUA series, the GLS, the GCD, with more in development. When used correctly, these luminaires can help mitigate the risk of SARS-CoV-2 infection. This article from LEDs Magazine discusses the Signify/BU story.
UVC disinfection should be used with other avenues in a multi-faceted approach to ensure that if a pathogen is not killed by one particular method, it is rendered inactive by the UVC. Since many pathogens can live on plastic and steel surfaces for three days, normal cleaning can leave behind contamination. Utilizing UVC products can help mitigate this. Source: IUVA.
Our new GUA series utilizes 254nm UVC wavelengths which can be used to treat both viral and bacterial pathogens. These indirect fixtures are either wall-mounted or hung inverted while the UVC treats the upper air cavity in the room. The GCD series also uses 254nm UVC to cleanse unoccupied rooms. This fixture hangs in the corner where the wall meets the ceiling.
It is important to understand the potential dangers UV lighting can present. Please be sure to heed all warnings when using these products. UV light can cause sunburn-like reactions and eye damage if exposed, or if luminaires are installed incorrectly.
We are also offering new versions of our FormFocus FFL and FFR products using 405nm near-UV LEDs. The LEDs in the new FFLD troffer and FFRD retrofit feature cutting-edge technology - light that can kill 99.9 percent of bacteria using a wavelength that is safe for both humans and animals.

LumenFocus' GUA product line of upper air germicidal luminaires can be used to reduce airborne pathogens - bacteria and viruses, including COVID-19. These products utilize low-wattage, ozone-free GUVT8 lamps producing 254nm UVC. An optional AirFocus system adds fans to the units for additional circulation. These products can be used in many applications:
- Conference Rooms
A specially designed polished aluminum reflector is optimized for dispersion of UVC wavelength for irradiation of pathogens. The GUA comes in a sconce (GUA S) and pendant (GUA P) option. Optional fans (the AirFocus, or "AF" option) mounted at the bottom of these units provide added circulation, pushing more air and pathogens into the eradication zone.
Our GUL series, like the GUA, provides upper air germicidal UVC illumination. These products use low-wattage, ozone-free PLL lamps to reduce airborne pathogens. There are two versions - a wall sconce (GUL S) and a pendant (GUL P). The sconce provides 180 degrees of UVC irradiation, while the pendant provides a full 360 degrees.
- Conference Rooms
Each GUL comes with an AirFocus fan standard on the bottom of the unit. This fan helps circulate air into the eradication zone and assists with pathogen elimination.
The GCD provides direct germicidal eradication, and is designed to be powered on when the room is unoccupied. The GCD hangs in the corner where the wall meets the ceiling. The GCD utilizes low-wattage, ozone-free GUVT8 lamps producing 254nm UVC. Constructed of durable cold rolled steel, it is available in silver (standard), white or black powder coated finish. A stainless steel housing option is available as well. The polished aluminum reflector is optimized for UVC wavelength for the irradiation of pathogens. A wireguard comes standard. The GCD is suitable for:
Like the GCD, the GLS and GLR provide direct germicidal eradication, and are designed to be used in unoccupied rooms. The GLR is a recessed lay-in fixture, while the GLS is surface-mounted. Both use low-wattage, ozone-free lamps producing 254nm UVC. The surface-mounted GLS is available in silver (standard), white or black powder coated finish. A stainless steel housing option is available as well. The GLR is constructed of white aluminum. The polished aluminum reflectors are optimized for the UVC wavelength for the effective irradiation of pathogens. A wireguard comes standard. The GLS and GLR work as a great compliment to the GCD - with the GCD mounted in the corners of the room, and the GLS/GLR providing additional irradiation in the middle or throughout the room as needed.
The GLS and GLR are suitable for:
- Conference Rooms
Note: Successful UV disinfection requires a systems approach taking into account dose, optics and safety relevant to the specific application. Please consult with the factory any questions or concerns. Avoid looking directly at the light and take necessary precautions during installation or maintenance of these products. Lamps used in the GUA, GCD and GLS/GLR series contain mercury.
With the FFLD and FFRD, we have introduced high performance disinfecting LEDs to our FormFocus product line. When the lights are kept on, these LEDs provide continuous disinfection for hard or soft surfaces, killing 99.9 percent of bacteria such as MRSA, C. Difficile, Salmonella and E. Coli.
The FFRD is a retrofit kit, available in 2x2 and 2x4 sizes, that can be installed into an existing troffer housing quickly and easily (3-5 minutes). The FFLD is a matching new luminaire.
Because the LEDs used in the FFLD and FFRD utilize a 405nm near-UV wavelength that is part of the normal visible LED spectrum, these products are completely harmless to humans and animals.
The FFLD and FFRD can be used in a variety of applications:
- Healthcare facilities
- Labs and clinics
Note: The FFLD and FFRD are engineered to eradicate bacteria over time, but not viruses.
The GAB is a germicidal air chamber that sits in a recessed 2x2 or 2x4 grid. It utilizes 254nm UVC lamps to provide anti-viral and anti-bacterial disinfection. The air chamber sits recessed into the ceiling, so there is no exposure of UVC into the space below.
Air from the room below is pulled into the chamber via fans in the center. Inside the chamber, air is dosed with UVC, which will kill or inactivate airborne pathogens including viruses, bacteria, fungi, yeast, and molds. Cleansed air is then recirculated into the room.
The GAB-C is an air chamber just like the GAB, but with an added LED down light component. Two rows of highly efficient LED arrays provide general illumination into the space below.
The GAB and GAB-C can be used in a variety of applications:
- Healthcare facilities
- Labs and clinics

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.
