COVID-19 has changed the landscape in many ways. Society has had to make many changes, but this 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.
According to the International Ultraviolet Association, UV technology can play a role in reducing the transmission of COVID-19. UV is a disinfectant for air, water and surfaces. This technology has been used for many years now. We are introducing a new UVC products - the GUA series, and the GCD. When used correctly, these luminaires can help mitigate the risk of COVID-19 infection.
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 the COVID-19 virus can live on plastic and steel surfaces for three days, normal cleaning can leave behind contamination. Utilizing UVC products can help mitigate this.
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 IllumiPure 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.
The new GAC LED germicidal air chamber utilizes a two-prong approach to attack airborne pathogens. The downlight utilizes anti-bacterial near-UV technology to disinfect hard and soft surfaces, while air is simultaneously circulated into a rear chamber that utilizes UVC LEDs to inactivate viruses (including COVID-19), bacteria and spores. Read more about all of these products below.

LumenFocus is a member of the International Ultraviolet Association (IUVA).
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. When mounted at the specified height, the UVC light produced by these luminaires will not come into contact with humans and pets. These products can be used in many applications:
- Conference Rooms
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. A proximity detection sensor comes standard with each GUA. This sensor turns off the fixture when motion is detected in the irradiation zone. A specially designed polished aluminum reflector is optimized for dispersion of UVC wavelength for irradiation of pathogens.
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. Like the GUA series, the GCD utilizes low-wattage, ozone-free GUVT8 lamps producing 254nm UVC. It is available in 1-lamp or 2-lamp versions. Constructed of durable cold rolled steel, it is available in 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. The GCD is suitable for:
- Conference Rooms
A reverse occupancy sensor powers off the unit when a person is detected in the occupancy zone. The GCD powers back on when the area is unoccupied.
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 and GCD series contain mercury.
If you have any questions or concerns about a project, you can contact us directly at firstname.lastname@example.org, or you can fill out the inquiry form on the GUA S, GUA P, or GCD product landing pages.
With the FFLD and FFRD, we have introduced high performance disinfecting LEDs from IllumiPure 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 GAC is a revolutionary, state-of-the-art pathogen eradicating luminaire - a combination disinfection lay-in and germicidal air chamber. It utilizes anti-viral and anti-bacterial lighting technology.
The anti-bacterial down light in the GAC continuously disinfects any hard to soft surfaces simply by keeping the lights on. It utilizes IllumiPure LEDs that are, like the FFLD and FFRD, near-UV and part of the normal visible LED spectrum. the down light is completely harmless.
Fans (or a single fan in the case of the 2x2 unit) circulate air into a rear chamber. Inside this chamber, 260-265nm UVC LEDs cleanse the air inside of pathogens (viruses, including COVID-19, bacteria and spores) with a 99-plus percent inactivation rate. The clean air is then circulated back into the room. The GAC circulates approximately 300 square feet of air every 10 minutes.
The GAB is a similar product to the GAC, just minus the down light component. The GAB sits in the ceiling and acts as a germicidal air chamber, using the same UVC rear chamber system as the GAB.
The GAC and GAB can be used in several applications:
- Healthcare facilities
- Labs and clinics
- May be placed in room, plenum or air duct
We are currently working on several new products to add to the UVFocus product line. We will add them to this page as they come available, so check back soon!
Among the many products in development:
- An "AirFocus" version of the GUA S and GUA P - with fans to help circulate air into the path of irradiation using 254nm UVC to maximize pathogen eradication (patent pending)
- GUL series - louvered 254nm UVC fixtures in a sconce and pendant, providing 180 and 360 lateral degrees, respectively, of upper zone irradiation (patent pending)
- Higher-volume version of the GAB with 254nm UVC, for higher volume air circulation and more air changes in the room
- Portable UVC tower for full room irradiation

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.
