Virginia Tech Completes Testing of LiteSheet LED UV-C Disinfecting Cabinet Against SARS-CoV-2

Jan. 4, 2021
Test Results Show a 99.95% Reduction of the Virus That Causes the COVID-19 Illness.

Forest and Blacksburg, VA —This past fall, Dr. Nisha Duggal and her team of scientists at Virginia Tech tested the efficacy of the LiteSheet UV-C Disinfecting Cabinet against SARS-CoV-2, the virus that is the cause of the COVID-19 pandemic, on surfaces.  Virginia-based LiteSheet Solutions’ innovative LED UV-C disinfecting cabinet is designed to decontaminate potentially deadly bacteria and viruses, like the COVID19 virus.  The cabinet finds practical applications in disinfecting equipment used in offices, nursing homes, medical facilities, schools, universities, restaurants, hotels and other locations.

“We tested the capacity of SARS-CoV-2 to infect cells after a 15-minute incubation within the LiteSheet UV-C cabinet or outside of the cabinet. We found that the level of infectious SARS-CoV-2 on a surface was reduced by 99.95% after 15 minutes in the cabinet,” said Dr. Nisha Duggal, Assistant Professor, Department of Biomedical Sciences and Pathobiology, College of Veterinary Medicine.

Duggal is also a member of the newly-created Center for Emerging, Zoonotic, and Arthropod-borne Pathogens at Virginia Tech.

Micro-organisms such as bacteria, viruses, cysts and mold are simple lifeforms that reproduce by subdivision, budding or by producing spores. Reproduction of these organisms is vital to their lifecycles and loss of their ability to grow and multiply is classified as cellular death and renders them harmless and no longer pathogenic. The LiteSheet LED UV-C Disinfecting Cabinet quickly and efficiently disrupts the lifecycle of bacteria and viruses, like COVID19.

By optimally positioning germ and virus killing UV-C LED modules inside the cabinet to eliminate blind spots, contents are disinfected within minutes. The germicidal effects of UV light are well known and medically researched. UV-C light wavelengths between 200 and 280 nanometers are used against bacteria, molds, and viruses.  The light penetrates through cell walls and disrupts the structure of  DNA molecules, prohibiting reproduction.  Because UV disinfection does not rely on chemicals or filtration materials, it can be used effectively and safely.

“The Virginia Tech study proves that by harnessing the power of UV-C light, we are able to kill 99.95% of viruses and bacteria, including the deadly COVID19 virus, the cause of the current pandemic,” said Roger Whyte, President and CEO of LiteSheet Solutions, “The LiteSheet UV-C Disinfecting Cabinet provides comfort by helping to make workplace tools, medical and personal items, and office equipment safe and hazard-free.”

The UV-C Disinfecting Cabinet research was facilitated by Virginia Tech’s Technical Assistance Program, administered by Continuing and Professional Education. Developed as part of the university’s outreach mission, this program enables faculty members to respond quickly to market needs requiring technical expertise and provides businesses with a streamlined process for accessing this knowledge.

All LiteSheet products are manufactured in Virginia with both US and imported parts to the highest specifications.  The LED UV-C Disinfecting Cabinet offers health and safety solutions for users backed by American-made reliability.

FDA Guidance

The FDA guidance for LiteSheet’s disinfection cabinet in response to COVID-19 is as follows. LiteSheet’s cabinet is recognized in Section B (2) as an Ultraviolet (UV) Disinfecting Device. Therefore, the LiteSheet disinfection cabinet does not require FDA approval for market in response to COVID-19

“In addition, during the declared public health emergency, FDA does not intend to object to the distribution and use of sterilizers, disinfectant devices, and air purifiers that are intended to be effective at killing the SARS-CoV-2 virus but do not already have FDA marketing authorization, without compliance with the following regulatory requirements where such devices do not create an undue risk in light of the public health emergency: prior submission of a premarket notification under section 510(k) of the FD&C Act and 21 CFR 807.81 or submission of a PMA Supplement under section 515 of the FD&C Act and 21 CFR 814.39, Registration and Listing requirements in 21 CFR 807, and Unique Device Identification requirements in 21 CFR 830 and 21 CFR 801.20. FDA believes such devices will not create such an undue risk where the performance and labeling elements in Sections IV.A and IV.B, respectively, are met. As an example, this would apply to a manufacturer of a new medical air purifier that has not been approved or cleared and that is effective in filtering out dust particles and bacteria, where the manufacturer would like to modify the filter mesh size in order to filter out viruses, including the SARS-CoV-2 virus.

Further, as described under Section A. Performance guidance the LiteSheet cabinet will meet the design, evaluation, and validation of performance relevant to the enforcement policies set forth in the document.
