The science

UVC LED disinfection is a more convenient, efficient, eco-friendly, cost-saving and quicker solution compared to traditional sanitization methods( alcohol, sanitizer, mercury lamps). These traditional methods have harmful side effects like irritation to lung mucosa due to chemical residue.

The UVC technology has been backed by the FDA and shows disinfection rates of up to 99.9%.  The products have  been registered with the EPA under EPA Establishment number 97583-CHN - 1.  Our product has been tested and passed the QuantadDose UVC Detection Card Test.  

The QuantaDose™ UVC intensity test card relies on calibrated word legibility starting at 300 µW/cm² when the word “ULTRAVIOLET” first becomes legible during exposure to UVC light.

The top indicator is needed to confirm UVC intensity is being measured in the lower test area and not UVA/UVB!

The letters UV-C glow brightly when measuring the correct UVGI wavelengths between 250 nm – 275 nm for a minimum calibrated reference point of 300 µW/cm² UVC intensity through simultaneous word legibility and letter visibility.

UVC radiation can cause severe burns (of the skin) and eye injuries (photokeratitis). Avoid direct skin exposure to UVC radiation and never look directly into a UVC light source, even briefly.  The UUVVEE portable sanitizer wand is equipped with a safety feature that prevents UVC exposure by automatically turning the wand off when tilted 45 degrees in any direction. 

According to consumerlab.com UV radiation kills viruses and bacteria by damaging their genetic material (DNA and RNA). Of the three main types of UV light, UVC (which has a wavelength range of 200 to 280 nm) is the most effective for inactivating viruses, with the most effect wavelength being about 260 nm (Lytle, J Virol 2005).

In order to be effective, the right "dose" of UVC must be applied. The dose is a function of the UVC intensity or "irradiance" from a specific distance from the object times the number of seconds the object is exposed. Irradiance is measured in milliwatts (mW) per square centimeter (cm2), and the dose of UVC is measured in millijoules (mJ) per square centimeter (cm2) of the object being irradiated. (In scientific terms, 1 mWs/cm2 =1 mJ/cm2).

So if your UVC lamp has an irradiance of 5 mW/cm2 at a specified distance from an object, then holding the lamp at that distance from the object for 8 seconds will deliver a dose of 40 mJ/cm2, because 5 mW/cm2 multiplied by 8 seconds = 40 mWs/cm2 or 40 mJ/cm2.

A dose of 40 mJ/ cm2 is generally considered sufficient to disinfect (99.9% reduction in infectivity) a wide range of bacteria and viruses, including certain coronaviruses that infect animals (Malayeri, IUVA News 2016).

According to consumerlab.com, in its published guidance for consumers, the FDA states that UVC radiation has been shown to destroy the outer protein coating of other coronaviruses and "may also be effective in inactivating the SARS-CoV-2 virus," but notes that "there is limited published data about the wavelength, dose, and duration of UVC radiation required to inactivate the SARS-CoV-2 virus."

A laboratory study (not yet peer-reviewed) showed that when pieces of fabric from N95 masks and stainless steel were contaminated with a high concentration of SARS-CoV-2 and then exposed to a large hospital-type UVC lamp (containing a large array of small, LED UVC lamps), it took about one hour for the virus to become undetectable on the mask but just about 12 minutes on steel. The distance from the UVC lamp to the objects was approximately 20 inches (50 cm), at which distance the lamp had an irradiance of just 0.005 mW/cm2 (or 5 microWatts/cm2 or 5 µW/cm2) (Fischer, medRxiv, 2020 — preprint). This means that the effective dose needed to kill the virus to the point of being undetectable on the N95 fabric was 18 mJ/cm2 and, on steel, it was just 3.6 mJ/cm2.

Bear in mind that extra time might be needed to disinfect surfaces of larger objects and those with curved surfaces which would require different lamp angles. Futhermore, as the FDA cautions, "It is important to recognize that, generally, UVC cannot inactivate a virus or bacterium if it is not directly exposed to UVC. In other words, the virus or bacterium will not be inactivated if it is covered by dust or soil, embedded in porous surface or on the underside of a surface..."
