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

Test Results Show a 99.97% Reduction of the Virus That Causes COVID-19

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.  

“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 99.97% after 15 minutes in the cabinet,” said Dr. Nisha Duggal, Assistant Professor, Department of Biomedical Sciences and Pathobiology, College of Veterinary Medicine.

Further, by leaving the SARS-CoV-2 sample in the cabinet for 30 minutes, the test shows a 100% reduction in the virus' capacity to infect cells. See the below chart for the comparison of exposure time within the cabinet verses the control outside of the cabinet.

WHY IT WORKS

WHAT IS UV-C LIGHT?

UV light has three wavelength categories: UV-A, UV-B, and UV-C. UV-C light wavelengths are between 200 and 300 nanometers. UV-C is germicidal and effective in breaking apart microorganisms, such as bacteria, molds, and viruses.

WHY IS UV-C EFFECTIVE?

Microorganisms 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 life-cycle. Loss of their ability to grow and multiply is classified as cellular death and renders them harmless and no longer pathogenic. When exposing microorganisms to UV-C light, the light penetrates through their cell walls and disrupts the structure of their DNA molecules, prohibiting reproduction. Because UV disinfection does not rely on chemicals or filtration materials, it can be used effectively and safely.

FREQUENTLY ASKED QUESTIONS

WHAT IS THE MAXIMUM CAPACITY OF LITESHEET’S CABINET?

The inside dimension of the cabinet is 18”x18”x18”. With this design, you can fit the following products and quantities as an example: Qty 13 N-95 masks, Qty 18 iPhone 11 smartphones, Qty 2 iPad Air tablets, Qty 2 Chromebook laptops (closed), or Qty 8 Xbox game controllers.

WHAT IS THE CYCLE TIME NEEDED TO KILL DIFFERENT VIRUS TYPES?

There are different irradiation cycle times required to kill different types of virus/pathogen types. For example, based on independent third-party testing, it takes the LiteSheet LED UV-C Disinfecting Cabinet 15-minutes to achieve a 99.97% kill rate for SARS-CoV-2, the virus that causes COVID-19. For reference, a germ chart is provided with the user manual and product spec sheet that shows the irradiation times required to kill specific pathogens.

WHAT IS FAR UV-C AND HOW IS THE LITESHEET TECHNOLOGY BETTER?

Light is a form of electromagnetic radiation in different wavelengths (nm). The UV spectrum is 100-400nm (UV-C to UV-A). The optimal germicidal wavelength, based on CDC guidelines, is 265nm. The FAR UV-C spectrum is 222nm. The wavelength of UV-C LEDs, which are used in the LiteSheet cabinet, is 275nm. Therefore, LiteSheet’s technology using UV-C is more efficient and much closer to the optimum wavelength than products using FAR UV-C. It is important to note here that the FDA specifies that manufacturer claims of disinfecting products must be substantiated with data. If the manufacturer cannot provide data that their product kills SARS-CoV-2, then the guidance from the FDA is to avoid the product. The LiteSheet LED UV-C Disinfecting Cabinet has been tested and can substantiate our claims of killing SARS-CoV-2. See the test results here and the test report here.

HOW DOES THE CABINET OPERATE?

The user manual can be found here or view the training video on this page above. 

CAN YOU PROVIDE AN OVERVIEW OF LITESHEET'S UV-C CABINET AND HOW DO YOU KNOW IT IS EFFECTIVE IN DISINFECTING ITEMS?

The LiteSheet LED UV-C Disinfecting Cabinet is designed to decontaminate contents from harmful viruses and bacteria while providing a safe environment for the workplace. By optimally positioning UV-C LED modules inside the cabinet to eliminate blind spots, contents are disinfected within minutes. Research and testing have shown that by exposing germs to UV-C light for a certain amount of time, at a certain energy level, and at a certain distance will render those germs inactive. We have provided an extensive chart of pathogens with the recommended times of exposure to UV-C to be used with our cabinet. See the user manual for detailed instructions. We are also including UV-C indication stickers with the cabinet that can be placed within the cabinet to assure the user that the items inside are receiving the required amount of exposure.

HOW IS UV-C MORE EFFECTIVE THAN WIPING DOWN ITEMS WITH SANITIZING WIPES?

Disinfecting chemicals can be toxic and harmful to both humans and the environment. Many chemical based sanitizing wipes require ‘standing time’ to be effective. For example, one of the most popular sanitizing wipe brands is only 99.9% effective in inactivating SARS-CoV-2 after leaving the chemicals on the surface for two minutes. Our cabinet is 99.97% effective against SARS-CoV-2 in 15 minutes and 100% at 30 minutes and there are no chemicals involved. Not all items can be disinfected by using sanitizing wipe (i.e. electronics). To completely disinfect items, all surfaces need to be accessible. This is achievable using the UV-C LEDs automatically while using wipes requires strict adherence to cleaning protocols. 

There are also strict guidelines on properly using sanitizing wipes to reach the proper sanitation level. The American Journal on Infection Control provided a research study discussing these challenges. 

IS IT SAFE TO PUT MY CELL PHONE IN THE CABINET?

Yes, UV-C LED technology is safe and effective in disinfecting cell phones and other electronic items.

WHAT KILL RATE IS GOOD ENOUGH (99.9% VS. 99.99%)?

At 99.97%, the LiteSheet LED UV-C Disinfecting Cabinet has the highest, proven kill rate against SARS-CoV-2.

HOW IS UV-C LED TECHNOLOGY MORE EFFECTIVE THAN MERCURY TUBES?

UV-C LED technology is more effective and offers many advantages compared to UV-C mercury tubes. For example, the life span of an LED is 20,000 to 50,000 hours compared to 2,000 to 8,000 hours for a mercury tube. LEDs are more environment friendly since they do not contain mercury and do not generate ozone that tubes produce. Physically, LEDs are available in a smaller form factor, which allows LED disinfecting products to be smaller in size with superior performance. Performance wise, LEDs have a lower power consumption than mercury tubes, and are more efficient since they need zero warm-up time.

HOW DOES UV-C WORK IN KILLING VIRUSES AND BACTERIA?

Disinfection performance is a function of the UV dose. The performance result is made up of the amount of LED energy being delivered over time, the distance of the energy to the surface being disinfected, and the duration the surface is exposed to the LED energy. All of these parameters are carefully engineered and validated for the LiteSheet LED UV-C Disinfecting Cabinet.

IS UV-C EFFECTIVE AS A GERMICIDAL AGAINST VIRUSES AND BACTERIA?

UV-C has been well studied and proven as an effective germicidal against viruses and bacteria.

HAS THE CABINET BEEN TESTED AGAINST COVID-19?

LiteSheet’s LED UV-C Disinfecting Cabinet was independently tested at a Class 3 Virology lab at Virginia Tech. The test results showed that the cabinet killed SARS-CoV-2, the virus that causes COVID-19, at a rate of 99.97% in 15-minutes. The kill rate was 100% in 30-minutes. The test consisted of multiple test events with repeatable results.

IS FDA APPROVAL REQUIRED FOR THE CABINET?

No, FDA’s guidance is found here

LiteSheet’s cabinet is recognized in Section B (2) as an Ultraviolet (UV) Disinfecting Device. The FDA guidance for LiteSheet’s LED UV-C Disinfecting Cabinet in response to COVID-19 is found on page 9:


“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.”


Therefore, the FDA does not require the LiteSheet LED UV-C Disinfecting Cabinet to be approved by the FDA for market in response to COVID-19. Further, as described under the 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. 

IS EPA APPROVAL REQUIRED?

No, approval is not required, however, the EPA does regulate UV-C devices under their pesticide guidance found here. The LiteSheet LED UV-C Disinfecting Cabinet is a regulated device requiring that LiteSheet provide data that shows that we meet the claims that we’re making.  The data provided by the class 3 virology lab at Virginia Tech shows that our cabinet meets our claims of killing SARS-CoV-2.
