The Vira UVC T8 LED Tube is available in four models. A retrofittable tube, which can be placed in an existing T8 Tube fitting, or full luminaire which can be installed independently to provide UVC sanitation in any area required. Or the more popular and highly advised for safety are the integrated sensor options. The Microwave Sensor model features an in-built microwave sensor, a safety function that automatically switches off the UVC light when presence is detected (this is also available with a Fixture). The sensor can also automatically turn the UVC T8 LED Tube on 30 seconds after all occupants have left the room.
