Abstract: There is provided an apparatus, system and method to treat air and surfaces using light. The apparatus comprises a hollow body having an inlet and outlet for passage of air. Treatment lamps are body mounted for movement between an air treatment position to treat air inside the body and a surface treatment position to treat air/an external surface. When installed in a room environment, the apparatus, via a system controller, operates in an air treatment mode, a surface treatment mode or an off mode. Room sensors (e.g. interlock and presence) communicate with the controller and the controller permits or prevents operation in the surface treatment mode accordingly. If any interlock sensor senses an open position or the presence sensor senses a presence (e.g. motion), operation in the surface mode is prevented. A remote control communicates with the controller to select an operating mode.

Abstract: An LED lighting system including an LED array including one or more LED lights, a main power supply supplying power to the LED array, and an emergency power source supplying short-term power to the LED array upon detection of a loss of power from the main power supply. The emergency power source consists of a super capacitor array charged by the main power source.
