Uses for UVC light

Updated 1/18/2021

With the rise of the coronavirus, people all across the nation have become extra sensitive towards disinfection and sanitization. Because of this, there has been a significant rise in the chemical sanitizer and disinfectant demand. Though yes, this is a common way to kill viruses and reduce the risk of contracting any viral or bacterial illness, it is certainly not the best option to go with, UVC LED light is.

What is UVC Light, and How Does It Work?

When you use any UVC sterilizer device, they use a method called ultraviolet germicidal irradiation (UVGI) This is a disinfecting concept that utilizes short wavelengths (somewhere between 200 and 300 nanometers) of UV light, which is called UVC. This UVC light can either deactivate or kill harmful microorganisms by disrupting their DNA and breaking up their nucleic acids. This means that those microorganisms will be debilitated and unable to perform their normal cellular functions, making them turn non-invasive to humans. For example, a handheld UVC light ranged between 254 - 280 can combat foodborne pathogens, yeasts, molds, and natural microbiota.

In a more straightforward visualization, the entire process is very similar to humans getting a sunburn. It is clearly painful, but most of the time, us humans can quickly recover. However, microorganisms do not have the same protective skin layer as we do and cannot survive prolonged UV exposure, even with less wavelengths. Within just a few seconds, 99.9% of the microorganisms die.

Is UV Disinfection Effective?

UVC light has been proven to kill a much more extensive range of harmful microorganisms than commercial chemical products. For instance, UV light can kill spores and mold, but many chemical resources cannot. It is also a dry method, meaning you never have to worry about moisture fostering new mold growth later on.

Another reason why this method is so effective, and why healthcare industries are heavily using UVC to sterilize, is because it can destroy antibiotic-resistant bacteria. Since UVC light is a physical method, bacteria can’t build an immunity to it. This is a massive benefit for people, especially for healthcare workers, because they can be confident that all viral and bacterial management is in full control, and nothing will manifest.

Uses for UVC LED Light

Please keep in mind that there are so many ways you can use UVC light, but here is a shortlist to give you an idea.

  • Smartphones

    A Seattle Times journalist named Bobby Caina Calvan stated that most smartphones are a germ breeding ground. It is estimated that there are 25,127 bacterial traces per square inch, which tells us that your phone just might be the dirtier than a public toilet seat. But with just a moment of UVC light on your phone, those germs will be gone.

    • Makeup Brushes

    Did you know that nearly 60% of all makeup users do not clean their makeup brushes regularly? If you do not clean your makeup brushes, they will accumulate product buildup, oils, and dead skin, which can become a breeding ground for bacteria. These bacteria will, in turn, hurt your clear skin goals, becoming a catalyst for acne and possibly rashes. This is why it is so incredibly important to clean your makeup brushes on a regular basis, especially with UVC light to avoid any toxic or chemical interaction.

    • Keys

    When was the last time you cleaned your keys? Think about it; those things carry everything that you touched in the store, in your home and everything else in between. Place then under the UVC light, and know all that built up adversities will disappear.

    • Door Knobs

    According to a test by Chuck Gerba, Ph. D., who is an environmental microbiology professor, only 68% of people wash their hands before leaving a restroom. Another study found that a common species that live on door knobs is E-coli. With this being evident, take the right precautions and sterilize your door knobs just in case. 

    • Kitchen Surfaces

      The most common bacteria on kitchen surfaces are salmonella, shigella, e-coli, norovirus, campylobacter, and hepatitis-A. This is a scary list to see, but with UVC light, you can ensure you will not ingest any contaminants that snuck in your food during preparation.

      • Vacuum Cleaner

      Vacuums can be a leading breeder device for harmful bacteria and endotoxins. Though they pick up bacteria from the floor, which sounds like a good thing, bacteria actually gets stuck in your vacuum bristles where other food crumbs are, and then multiplies. You don't have to stop vacuuming, though. Just do it safely and leverage UVC light after cleaning your floors to stunt bacterial growth.

      Problems with Liquid Chemical Sanitizers

      Chemical disinfectants are "great" at getting rid of bacteria, viruses, and other microorganisms, but they are certainly not the best option to rely on. First and foremost, most liquid chemical disinfectants are toxic and are made up of chemicals that can harm your wellbeing. This means that when in constant contact with humans, both topical and inhalation, it can cause severe health issues and chronic respiratory conditions. In addition, when these chemicals get washed down the drain, it has significant repercussions on the ocean and wildlife.

      Another main problem is that many traditional antimicrobial agents can develop antibiotic-resistant bacteria. This is a considerable concern within the medical field, which is why so many are turning this solution down and going with UVC light instead since it is not a catalyst for bacteria resistance.


      UVC disinfection is a vital resource if you want a safe and effective way to kill bacteria and germs in a short amount of time, including traces of the coronavirus. Investing in a handheld UVC light device is entirely eco-friendly, 100% chemical-free, and a healthy alternative than the typical harsh chemical methods. By trying it out, you really have nothing to lose and everything to gain from it. In the end, we are entirely confident that once you get to witness the benefits and seamlessness firsthand, you will never go back to chemical sanitizers again.
