UV light, short for ultraviolet light, actually uses the C-band of three segments of the ultraviolet range. The A and B bands are significantly different from the C-band of UV. UV Disinfection equipment utilizes light measured at 254 nanometers. This bandwidth lies in the C-band segment. UV disinfectant equipment lamps vary in power ratings. 

​

Most pathogens are susceptible to the 254 bandwidth. Our UV disinfection equipment projects light at this bandwidth. The UV light disrupts genetic material in the reproductive regions of pathogens. Humans have pathogens residing in their bodies at all times. Pathogens must reproduce and grow to extremely high populations before they cause enough damage to cause illness.

 

Many pathogens can colonize on surfaces outside of the human body. Blood, soil, human waste, even water can provide an environment for pathogens to quickly colonize. These materials often settle in cracks and indentations that are hard to reach. Unfortunately, attempts to "deep clean" or detail clean, actually move contaminated material from those hiding places onto "frequent touch" surfaces. Pathogens are easily transferred from those location to ourselves and others. UV disinfection equipment exposes these pathogens and renders them harmless, before they can colonize further.

​

The CDC has gathered data from many different studies that have determined how much UV light exposure is needed to de-activate specific pathogens. Exposure is a combination of the power of the light and how long it illuminates the pathogen. The amount of UV light needed to de-activate a specific pathogen is called its "fluence".  For instance it might take a 10 minutes, for a10 watt UV light,10 feet away, to de-activate a Covid-19 virus. It might take a 30 watt UV lamp only 3 minutes to de-activate the same pathogen, when it's10 feet away.
