An array of outdoor lighting operates mainly in independent mode wherein sensing, communication, and control processes take place between the various lights of the array. Additional communication and control may occur between the array and a control station by means of a master/coordinating node that transmits and receives signals to the control station via call phone and/or satellite. The system may be tied to the internet for dissemination of data and/or data analysis gathered by means of the multiple poles/devices of the array. The independent-array and/or the master-to-station network and communications may be adapted for energy-saving processes; power-receiving from or power-providing to the grid, renewable power production and storage by means of solar panels and/or wind turbines and associated batteries or other storage equipment; and/or to Wi-Fi hot-spots, public safety alarms, information, or advertising to the public or information/data-analysis to customers. Preferred members of the array have solar-panel-powered lights, which may charge batteries and optionally supply energy to an electrical grid. In arrays cooperating with the grid, the grid may optionally charge the batteries of the array during off-peak hours. The preferred lights include LED modules that may be aimed to establish desired light patterns.
