UV-C light is ultraviolet (UV) light with an invisible, electromagnetic radiation that falls between 180 and 280 nanometers (nm) in wavelength.

Ultraviolet light can be split in three categories of wavelength ranges: UV-A, UV-B and UV-C. You might have heard of ultraviolet light like UV-A and UV-B light before because those kinds of UV light are well-known. Compared to aforementioned types of light, UV-C light is more intense. For this reason, UV-C light makes it possible to destroy DNA from germs in a very efficient and fast way.

UV-C light is able to ionize organic molecules and altering their DNA and RNA, which makes it an excellent tool to disinfect air, water and surfaces.  It destroys their ability to multiply and cause diseases! That is why UV-C is often called ‘germicidal ultraviolet light’.

Is the UV-C Light Technology new?

Yes and no.

Many people assume that the only reason UV-C light functions as a sterilization tool, must have been because of the struggle to beat COVID-19. Incorrect! UV-C light was already implemented in many sectors way before COVID-19 has seen the light. Early on – almost a century ago - the health care sector f.e. had already discovered the advantages of ultraviolet light for sterilizing purposes.

The health care sector adopted this sterilizing method on a big scale decades before COVID-19 appalled us. In hospitals this technology is still used to sterilize patient rooms and surgical instruments. Aside from health care, UV-C also booked already over 10 years of success in the food industry to fight germs such as Listeria, Salmonella, Staphylococcus and other micro-organisms.

On the other hand, consumer-friendly products like f.e. our LUMISAN smart bottles with sterilization function, are recent. We think UV-C might be called a ‘new’ technology in terms of consumer-friendly products. We are cheerful that the UV-C market is now ready for expansion to consumer goods. The technology is ready and it also seems like people are beyond excited to add these products to their daily routines. It seems like they value their health even more than before the pandemic.

What are the advantages of UV-C light?

UV-C light is a popular sterilizing method because it simply does the trick! It is able to kill up to 99,99% of bacteria. The same goes for viruses: UV-C light inactivates up to 99,99% of them.

But why don't we just use old-fashioned mops and disinfectants? Cleaning works fine because it reduces the amount of contaminents present, but this method is not flawless and, in addition, takes a lot of time and labor. We admit that sterilization isn’t flawless either, but it is found to be a great and simple tool worldwide!

Important is also the impact of chemicals. The UV-C light technology is a non-chemical tool to sterilize air, water and surfaces. Nowadays, UV-C light is used on a big scale because it clearly is the easiest way to sterilize air, water and surfaces fast. In fact it is also quite cheap in the long run, compared to f.e. chemical disinfectants.

What are the dangers of UV-C light?

UV-C light is intense ultraviolet light. You’ve probably heard sometime that you must always keep your eyes closed under a tanning bed because of the UV rays. That is 100% correct, because UV-A and UV-B light are able to damage your eyes and skin.

For this reason, contact with UV-C light is also dangerous. This light is even more intense than light from a tanning bed for example and will immediately cause damage to the eyes and skin. What do we mean by damage? It can cause pain, light sensitivity and a gritty sensation in your eyes.  Aside from damage to the eyes, it causes skin damage, comparable to a sunburn but way faster.

That is why, first of all, we inform you about the dangers of UV-C light. Secondly, we make sure our products are consumer-friendly. We added safety measures like sensors to our products, to make exposure to UV-C light impossible when the products are used in a normal way. All our products are of course in conformity with EU regulations and marked with a CE-label.

Furthermore we would like to warn you that the UV-C market is full of ‘competitors’ that tend to ignore all safety measures. Those companies sell products like UV wands that are likely to expose a user’s eyes or skin directly and continously to the UV-C light. We’ve also seen ‘competition’ of companies selling UV-C sterilizing bottles without any sensors at all.

UV-C products are great but they require some caution. We hope we informed you well about the dangers of UV-C light. Do not let it stop you from using UV-C products though. UV-C is the future!

Does UV-C light kill the coronavirus?

Research on COVID-19 is still a work-in-progress since this type of virus is quite new. The full efficacy of UV-C light against SARS-CoV-2 (which is the coronavirus causing COVID-19) is tested and the results so far are encouraging!

The FDA (Food and Drug Administration of the United States of America) stated that UV-C light is a known disinfectant for air, water and nonporous surfaces. UV-C light proved its efficacy in the research of SARS-Coronaviruses before. Now, the FDA says UV-C light may also be effective in inactivating the current SARS-CoV-2 virus. (Read full statement here)

As a result of the pandemic, UV-C light currently is bigger than ever in health care. In Kansas for example, a UV-C drone was developed to fly through contaminated spaces. It sterilized everything it came across. Also seen in the United States is a UV-C ceiling fan that sterilizes the air in a room.

What if your UV-C device is defective or your UV-C lamp is broken?

Never try to repair the product yourself. Never! First of all, you’ll immediately lose your warranty rights. Most importantly, it may harm you. Never attempt to fix the product yourself. Please warn us!
