What the Heck is UVC and Why We Want It

Updated: Oct 7, 2020



We all know about the general spectrum of visible light and its range of seven colors from red to violet, but just beyond the visible violet color wavelength is the part of the spectrum known as the ultra violet region with wavelengths ranging from 10nm to 400nm.

Ultraviolet wavelengths are further broken down into three ranges: ultraviolet A, ultraviolet B and ultraviolet C. Why is this important? It turns out that each range of ultraviolet radiation has different levels of biological activity, with UVC being the most powerful and the most damaging to living organisms.

However, thanks to earth’s protective atmosphere (Thank you, Earth), UVA, with wavelengths ranging from 315-400nm, is the only type of ultraviolet radiation that reaches the earth’s surface in significant quantities. We’re most familiar with ultraviolet wavelengths because that’s the wavelength of light that causes tanning (UVA, for example is used in tanning beds), skin cancer, age spots, skin aging and wrinkles. Thankfully, the UVC (100-280 nm) and UVB (280-315nm) most destructive to living tissues (including our DNA), is absorbed by our atmosphere.

UVC: Earth’s natural bioweapon

Since the late1800s it’s understood that artificially produced UVC can be harnessed to kill microorganisms, and consequently has become a staple method of sterilization in hospitals, airplanes and factories. It’s also fundamental in the process of sterilizing drinking water because many parasites are resistant to chemical disinfectants (such as chlorine), but, you guessed it – UVC can eliminate them. UVC is a kind of biologically active radiation, and breaks up the DNA of the pathogens that harm us – rendering them (not us) dead.

But there is a danger, because UVC is so powerful, it should not be used directly in the presence of people. UVA and UVB can tan your skin in a couple of hours of exposure, but exposure to UVC would fry us in seconds! We can’t just wander around the office or grocery store using a UVC light sabers to kill off all the pathogens floating around and expect to disinfect the entire area, it’s just too dangerous. You’ll shoot your eye out, kid.

Harnessing the power of UVC at home

So, what’s the solution? UVC technology properly used saves lives. UVC has been in use for nearly 150 years in hospitals and healthcare facilities, and now we can benefit from the same technology in our homes and in the workplace. UV Defense has a host of UVC products, including germicidal bulbs that fit into nearly any HVAC system or ductwork. Any harmful UVC light is hidden away (where its most effective, anyway) while at the same time, eliminating 99.9% of airborne viruses, mold, mildew and other pathogens.
