About Lit Thinking™

Founded in 2022, Lit Thinking™ is a private technology firm born out of a shared vision: to enable people to interact more safely and effectively indoors. We understand the importance of the indoor spaces where we live, work, learn, and play, and we’re dedicated to enhancing the quality of these environments. 
We are a passionate team of scientists and engineers who are changing the world. Our mission is to create safer, healthier, and more productive indoor environments.  By funding state of the art research, Lit Thinking™ is setting the new standard for applying Far-UVC light and other new technologies safely and effectively. All powered by proprietary software that enables, informs, and empowers businesses to maximize indoor air quality.
Our core focus is the innovative use of Far-UVC light technology. While UVC is already common in sectors like food production, water purification, and healthcare settings, we’re pioneering the use of a specific wavelength, Far-UVC, to create safer and healthier indoor spaces. This breakthrough technology can be used effectively in occupied spaces without harm to the human body, promising to dramatically improve building health and reduce the presence of aerosolized pathogens.

Far-UVC and Safety

Far-UVC is a subset of high energy, short wavelength UVC light (200-230nm) under the umbrella of ultraviolet light (100-400nm). As with all UV (ultraviolet) light, these wavelengths are invisible to the human eye, but can impact us and our surroundings. Far-UVC is not naturally occurring, as all UVC light from the sun is absorbed before reaching Earth. UVC and Far-UVC light can be generated through specialized bulbs and LEDs to kill or inactivate microbes.
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.

Testing and Research

UVC and Far-UVC light has been extensively studied over the last century. Far-UVC light can inactivate bacteria, viruses, and other microorganisms in the air, reducing the risk to humans. Read about the history of UVC light and its potential for the future in this review (https://pubmed.ncbi.nlm.nih.gov/24067444/). Also, check out our research page for more articles.
Yes, multiple peer-reviewed studies have shown that Far-UVC light is effective against human coronavirus. Check out our research page for links to existing studies. We will continue to update this page as research becomes available.


Visium™ is UL Certified. A UL Certified product not only meets rigorous safety standards but comes with the powerful endorsement of the UL mark, a universally trusted symbol that signals to consumers and industry professionals alike that the product has passed stringent, independent testing for safety and reliability. This mark is not just a badge—it’s a declaration of superior compliance and security. On the flip side, a UL Compliant product, while tested to meet the same stringent UL standards, lacks this prestigious mark because it’s certified by another company. It may be safe, but without the UL seal, it doesn’t carry the same weight of assurance that comes with a direct UL certification. The UL mark is not only about compliance; it’s about peace of mind, a promise that the product stands up to the highest scrutiny.
Yes, we are an EPA registered company. As our devices are registered and built in an EPA registered facility and meet all required guidelines to ensure the safety of our products.
Air and surface cleaning to reduce bioburden is federally regulated by EPA under FIFRA. We are an EPA registered company.
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.
We are excited to speak with you about Lit Thinking™ and its advancements in Far-UVC technologies. Please visit our contact us page and fill out the form. A member of our team will get back to you as soon as possible.
