What is UltraViolet C (UV-C) Light?
UV stands for ultraviolet light. Ultraviolet light represents the frequency of light between 400 nanometers (nm) and 100nm. Falling outside the visible spectrum, ultraviolet light cannot be seen with the naked eye.
Within the UV Spectrum, there are three distinct bands of light: UV-A, UV-B and UV-C:
- UV-A (400nm-315nm): The long wave UV Light (400nm to 315nm) or UV-A refers, to what we commonly call “black light.” This is the longest wavelength region and has the lowest energy. UV-A represents the largest portion of natural UV light.
- UV-B (315nm-280nm): The UV-B Light (315nm to 280nm), or mid-range UV, causes sunburn.
- UV-C (280nm-100nm): The germicidal UV Light (280nm to 200nm), or UV-C, is effective in microbial control. Scientific research has proven it's the most effective frequency for microbial destruction is between 280nmand 200nm, which is within the UV-C band.
Harnessing the power of UV-C Light has proven to be extremely effective & efficient at killing microorganisms since the 1800's. Currently, UV-C Light is widely used in water purification, hospitals, bacteriological research facilities, military & aerospace fields as well as a variety of other applications around the globe. This powerful light irradiates micro-organisms & instantly destroys their DNA & RNA forcing them to lose their ability to reproduce & survive, thus killing them in only a few seconds of exposure. The sun produces this powerful band of light. Fortunately for life on Earth, UV-C Light is mainly filtered out by the ozone layer to prevent any harm.
UV-C disinfection & sanitizing is a purely physical cleansing method requiring no additional products & is free from any offensive odors or by-products.
