The Beacon Lamp

The Problem

COVID-19 (also known as Coronavirus or SARS-CoV2) is a novel coronavirus first discovered in 2019. With a high rate of transmission and growing body of knowledge on its impact, it has disrupted the health and well-being of populations the world over. As researchers continue to test and analyze the growing body of information, efforts are under way to mitigate the spread of the virus.

Inspiration

The utility of UV light in the deactivation or killing potentially harmful pathogens has been discussed for over 100 years. Evidence provided by the WHO and the CDC suggest heat and humidity can help kill a virus, and one such claim included the use of sunlight therapy (UV rays) to reduce mortality rate during the 1918 pandemic (1).

Additional studies have shown the efficacy of UV light in deactivation of similar viruses (i.e., SARS-CoV) that are also transmitted in a similar manner: via droplets in the air and on surfaces. However, traditional UV lights at market (254-nm lights) are harmful to humans upon exposure.

The electromagnetic spectrum ranges from 1 picometer 100,000 kilometers. It includes X-Rays (10 pm to 10 nm), UV Light (10 nm to 400 nm), Visible Light (400-700 nanometers), and other forms of Infrared and high frequency radiation.

Far-UVC light is effective at deactivating or killing harmful pathogens but safer for humans than traditional UV lights. The 222nm Far-UVC light can enable safer work environments, cleaner transportation, and reduce the risk of transmission in highly trafficked locations like grocery stores and medical offices.

The Beacon Disinfectant Lamp

We began developing the Beacon Lamp prototype in March 2020 to ensure science-back technologies were brought to essential workers and communities in need as rapidly as possible.

Our priority was, and remains, finding a safer alternative to traditional UVC light, one that can reduce the spread of a pathogen, and is safer for human exposure.

The Science Behind a Safer UVC Disinfectant Lamp

We rely on credible and proven research.

222-NM FAR-UVC EFFECTIVENESS:

222-nm FAR-UVC inactivates a wide spectrum of microbial pathogens

  • 222-nm UVC is able to inactivate a wide spectrum of microbial pathogens. Although the germicidal effect to the fungal hyphae and spores is low, 222-nm UVC exhibited stronger germicidal effect to the bacterial endospores than conventional 254-nm UVC.(1)

222-NM FAR-UVC SAFETY:

Long-term effects of 222-nm FAR-UVC

  • Chronic 222 nm-UVC irradiation did not induce skin tumors.(2)
  • Data clearly indicate that even a relatively high dose of 222 nm-UVC irradiation does not induce either effect linked to skin tumor formation inflammation and immunosuppression.(3)
  • Results from testing conventional 254-nm and the 222-nm: Skin penetration is significantly less.(4)
