Questions

Visium emits Far-UVC light at the 222 nm wavelength, which has been shown to inactivate pathogens without penetrating human skin or eyes when properly designed and installed. This allows Visium to operate safely and continuously (24/7) in occupied spaces.

Traditional UV robots and towers typically emit UV-C light at 254 nm, a wavelength that is well established to be harmful to skin and eyes. As a result, these systems can only be used in unoccupied rooms as an episodic treatment. They require trained staff to deploy, rooms to be vacated during operation, and time for setup and removal — all of which can increase cost and delay room turnover.

Visium is designed as installed infrastructure that works continuously in the background, rather than a manual, intermittent, labor-intensive process.

Yes. Visium uses Far-UVC light at 222 nm and is designed for continuous operation in occupied environments. Visium is the first Far-UVC device to receive UL 8802 certification (Risk Group 0), indicating it meets the most stringent safety classification for continuous human exposure. When installed according to instructions and at the appropriate ceiling height, Visium can operate 24/7 in occupied spaces.

Peer-reviewed research indicates that properly designed Far-UVC systems can inactivate pathogens without penetrating living human skin or eyes. Visium fixtures are designed to operate within recognized exposure guidelines and applicable safety standards.

No. Visium is intended to supplement existing cleaning and disinfection protocols, not replace them. It functions as a continuous, passive layer of pathogen reduction that operates between and during routine cleaning activities, addressing both airborne and surface pathogens as they are introduced into the space.

Peer-reviewed studies have noted Visium and other Far-UVC technologies as an important adjunct to manual cleaning, particularly in healthcare environments where recontamination can occur rapidly and where traditional cleaning addresses surfaces episodically but does not continuously treat the air. By operating continuously, Visium helps fill a critical gap between cleaning cycles.

Visium is designed to reduce pathogens in both the air and on exposed surfaces. Airborne pathogens are addressed continuously as they circulate through the space, while surface reductions occur over time on illuminated areas.

Peer-reviewed research has demonstrated the effectiveness of Far-UVC in both contexts. In Eadie et al., researchers showed that Far-UVC inactivated aerosolized Staphylococcus aureus in a room-sized chamber in under five minutes. In Memic et al., researchers demonstrated that Visium significantly reduced MRSA contamination on surfaces in a simulated operating room environment.

Multiple published studies have reinforced both the efficacy of Far-UVC against bacteria, viruses, and fungi and the safety of its use in human-occupied spaces, supporting Visium’s role as a continuous, dual-action approach to pathogen reduction.

Far-UVC begins inactivating pathogens as soon as it is operating. Because Visium runs continuously, reductions accumulate over time rather than relying on a single disinfection event. To see how Visium can work in a room environment, contact us to request a custom Visium Blueprint which provides a detailed analysis and performance data for your space. 

Visium is used across a range of environments, including healthcare facilities, schools and universities, athletic and training facilities, commercial spaces, and agricultural or veterinary settings. 

Visium fixtures are designed to accommodate a range of ceiling heights based on the lamp module. Clear Optic lamp modules are typically recommended for ceilings 9’4″ and higher, while Diffused Optics are available for spaces with lower ceilings.

Visium fixtures are available in recessed, surface-mounted, pendant, and sealed configurations to support a wide range of ceiling types and environments. Recessed, surface, and pendant fixtures are designed for occupied indoor spaces, while Visium Apex is a sealed, industrial-grade fixture intended for more demanding environments such as agricultural, veterinary, and other rugged applications.

Fixture selection is typically based on ceiling type, ceiling height, and the physical characteristics of the space. Recessed fixtures integrate into finished ceilings, surface fixtures support retrofit scenarios, and pendant fixtures are well suited for open ceilings and high bays.

Visium fixtures are installed by any licensed electrician and require a standard 120–277V electrical connection. Installation is similar to installing a traditional architectural light fixture and integrates with existing electrical infrastructure. Installation requirements may vary by fixture type and environment.

Our solutions are automated from our central operating system to sanitize the air quickly and effectively. Various sensors on the Visium device and algorithms are used to estimate the sanitization effectiveness and overall indoor air quality.

Lit Thinking released its first commercial solution in 2023. The Lit Thinking Visium is fully automated, simple, and safe, providing constant cleaning of indoor air. Visium uses 222nm Far-UVC technology to sanitize buildings constantly. This product is accompanied by the Lit Thinking desktop and mobile app providing full automation control and adjustments, as well as status updates on the cleaning of individual rooms. As technologies continue to evolve, we are at the forefront of pioneering the next generation of Far-UVC solutions. Stay tuned for upcoming announcements and product enhancements later this year.

UVC light is strongly absorbed by DNA, RNA, and proteins of cells and microbes. When absorbed, DNA and RNA develop breaks in their strands that cannot be repaired after a certain amount of damage is accumulated. Proteins are similarly inactivated by UVC light, limiting the microbe’s ability to repair the damage from the UVC light. The exposed microbes are unable to reproduce, effectively killing them.

Yes, Far-UVC is safe for use in occupied spaces. Far-UVC has a very short penetration depth. It’s unable to pass through most material, including glass and plastic, making it easy to contain. Far-UVC penetration depth is so short, it is unable to pass through the dead layer of skin all humans have, or even the protective tear coat of our eyes.

Most commercial use of UVC light uses 254nm light (we call traditional UVC). The difference between traditional UVC and 222nm UVC is that 222nm UVC is a shorter wavelength. 222nm UVC does not penetrate skin and other materials as well as traditional UVC, allowing 222nm light to be used in ways traditional 254nm cannot.

UVC targets the DNA and proteins of microbes, making it a broad-spectrum solution for microbe removal. UVC has been demonstrated to inactivate microbes from viruses and bacteria to spores and molds, including antibiotic resistant pathogens. The efficacy of UVC light has been demonstrated and reported against most common contaminants and human pathogens, including E. coli, M. tuberculosis, Salmonella, MRSA, C. difficile, Acinetobacter, influenza, hepatitis A, and SARS CoV-2, to name a few.

Far-UVC technology has the potential for use in various settings, including healthcare, commercial buildings, sports applications, and government spaces, to reduce the burden of pathogen in the air in vital spaces.

Yes. The Occupational Safety and Health Administration (OSHA) recommends a maximum amount of UVC light workers should be exposed to within an 8-hour period. This recommendation is based on the guidelines set by the American Conference of Governmental Industrial Hygienists (ACGIH), updated most recently in 2022. Our solutions conform to these recommendations.

Yes, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) have included UV-based air cleaning devices in their most recent recommendations. While Far-UVC is a relatively new technology, it is already being actively considered and has the potential to meet or exceed indoor air quality standards once it becomes more widely adopted.
