Vyv’s lights and light technology meet international standards for continuous and unrestricted use around people, pets and plants.
Because the types of porphyrin molecules found in humans, animals and even plants are not photoactivated by light in Vyv’s 400-420nm range, our light technology can be used continually and without restriction. There have been numerous studies performed and papers written about using this visible light. Multiple scientific, peer-reviewed studies have exposed mammalian and human cells to these wavelengths and have shown that antimicrobial irradiance levels are fine for unrestricted use. In addition, all these studies were conducted at much higher intensities of light than our products. And all found that their applications had no negative impact on humans, animals, plants or on facility operations or any surface materials such as plastics, rubber, insulation, etc… This is very different from UV-C light. Vyv products have also been installed in patient care areas throughout hospitals since as early as 2013.
