A lighting control server configured to control a distributed lighting system comprising a plurality of sets of physically distributed lamps for street lighting or other outdoor lighting systems in a given area or geographic region, each lamp being controllable through a wireless lamp control module, said lighting control server comprising: a communication interface configured to communicatively couple the lighting control server to a regional network interface, RNI, that in turn communicatively couples to a radio network providing two-way radio links with the wireless lamp control modules; and a control circuit operatively associated with the communication interface and configured to selectively reduce an aggregate electrical load of the distributed lighting system by being configured to: determine a set of lamps to control within the distributed lighting system to place into a reduced-consumption state according to a defined lighting reduction pattern stored on the lighting control server; and send lighting control commands to the wireless lamp control modules associated with the determined set of lamps to effectuate the defined lighting reduction pattern in the distributed lighting system; characterised in that the reduced-consumption state comprises an off state, and the control circuit is configured to generate further lighting control commands for at least one wireless lamp control module associated with at least one lamp that is adjacent to a lamp that is or will be turned off to effectuate the lighting reduction pattern, wherein the further lighting control commands are brighten commands, such that the one or more adjacent lamps partially compensate for the loss of illumination from the lamp that is or will be turned off. a communication interface configured to communicatively couple the lighting control server to a regional network interface, RNI, that in turn communicatively couples to a radio network providing two-way radio links with the wireless lamp control modules; and a control circuit operatively associated with the communication interface and configured to selectively reduce an aggregate electrical load of the distributed lighting system by being configured to: determine a set of lamps to control within the distributed lighting system to place into a reduced-consumption state according to a defined lighting reduction pattern stored on the lighting control server; and send lighting control commands to the wireless lamp control modules associated with the determined set of lamps to effectuate the defined lighting reduction pattern in the distributed lighting system; characterised in that the reduced-consumption state comprises an off state, and the control circuit is configured to generate further lighting control commands for at least one wireless lamp control module associated with at least one lamp that is adjacent to a lamp that is or will be turned off to effectuate the lighting reduction pattern, wherein the further lighting control commands are brighten commands, such that the one or more adjacent lamps partially compensate for the loss of illumination from the lamp that is or will be turned off. determine a set of lamps to control within the distributed lighting system to place into a reduced-consumption state according to a defined lighting reduction pattern stored on the lighting control server; and send lighting control commands to the wireless lamp control modules associated with the determined set of lamps to effectuate the defined lighting reduction pattern in the distributed lighting system; characterised in that the reduced-consumption state comprises an off state, and the control circuit is configured to generate further lighting control commands for at least one wireless lamp control module associated with at least one lamp that is adjacent to a lamp that is or will be turned off to effectuate the lighting reduction pattern, wherein the further lighting control commands are brighten commands, such that the one or more adjacent lamps partially compensate for the loss of illumination from the lamp that is or will be turned off.
