New Sensors + Systems For Theatres Looking To Eliminate COVID

Along with the UVC LED lighting, Meridian Hall, Meridian Arts Centre, and the St. Lawrence Centre for the Arts are all installing new sensors throughout their theatres to monitor air quality.

Johnston is the Chief Technology Officer of NEXNORD, a company that has created an LED light that uses powerful UVC rays to target viruses, like COVID-19. According to Johnston, the company’s light is so powerful that it takes .07 seconds to start killing bacteria and viruses within two meters of the light. “It’s something that is very powerful, and it actually hits the DNA and the RNA, and destroys the carbon bonds and then it can no longer replicate- and it’s dead,” Johnston said. Ultraviolet (UV) rays can’t be seen by the naked eye, but are naturally emitted by the sun. UVA and UVB rays are what cause humans to tan, but UVC rays are absorbed by the atmosphere. It is the highest energy portion of the UV spectrum—so powerful it can damage human tissue. But by sealing their lights inside the air duct system, the company can disinfect the air without exposing the light to humans.
