NOVELTY - The array (10) has a set of light assemblies (12A-12F), where each of the assemblies includes a light source (18), and a communication module (24) for communicating a value of an operational parameter of the assemblies to a coordinator. The coordinator receives the values, and compares the values to determine a median value. The coordinator causes each of the assemblies of the array to conform the operational parameter to the value of the parameter at the assemblies that communicates the median value.    USE - Lighting array i.e. solar-powered lighting array for use in parking lots, walkways, airport runways and park areas. Can also be used in street lamp.    ADVANTAGE - The array ensures that a time of collecting information from the assemblies can be offset from anticipated transition times, and each assembly can be programmed to wait for a designated amount of time before sending last transition time to the coordinator so as to avoid problem of all assemblies talking to the coordinator at once, so that all the assemblies can receive instructions at the transition times. The coordinator can be programmed to poll the assemblies individually or in smaller groups, so that interference and noise can be avoided, and the polling times can be offset from the anticipated transition times, thus ensuring that all assemblies can be able to receive instructions at the appropriate time. The array is controlled to ensure that any outlying light is brought into synchronization with the array, despite any variation in locally determined transition times that is responsive to overall lighting conditions around the lighting array.    DETAILED DESCRIPTION - The operational parameters are battery charge levels, solar panel charge readings, solar panel voltage readings, collected solar power levels, battery temperature readings, light source temperature readings and signal strength. An INDEPENDENT CLAIM is also included for a method for synchronizing a lighting array.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of components of the lighting array.
