It is possible to obtain a sanitizing or even disinfecting effect with LED lighting. Our specially selected wavelengths contribute to the oxidation of certain porphyrin inside the cells of certain microorganisms, thus neutralizing several pathogens or viruses at the cellular level. Continuous usage of disinfection wavelengths within the visible spectrum is 100% safe for humans, animals, and plants. It is also possible to disinfect or inactivate pathogens and viruses by destroying their DNA with the help of ultraviolet light, which has a neutralizing effect on all living organisms and must be contained within a secure space so it cannot harm the occupants of the indoor location.
