A controllable power and lighting arrangement suitable for use in commercial and/or domestic applications in which an LED array comprising LED lights I is provided, the LED lights being powered by an AC low voltage (less than 50V RMS) power supply. The low voltage AC power distributed to the array is linked to a main transformer E and is distributed by bus bars F2, F1, G, H, such as aluminium tubular bus bars. The AC power is converted to low voltage DC by rectifiers associated with each LED light or group of LED lights. Means for control of the LED lights, for example by power line communication or wireless link is provided. The powering of non-LED based devices from the bus bars and application to providing lighting for plants in a domestic or commercial growth system are envisaged. |
