Street Light Control Systems
A number of street light control systems have been developed to control and reduce energy consumption of a town's public lighting system. These range from controlling a circuit of street lights and/or individual lights with specific ballasts and network operating protocols. These may include sending and receiving instructions via separate data networks,at high frequency over the top of the low voltage supply or wireless. Various protocols have been developed as well as compatible hardware for most types of lighting.

“If I should go out of church whenever I hear a false statement I could never stay there five minutes. But why come out? The street is as false as the church, and when I get to my house, or to my manners, or to my speech, I have not got away from the lie.”
—Ralph Waldo Emerson (1803–1882)
““Come unto me,” [Krokowski] was saying, though not in those words, “come unto me, all ye who are weary and heavy-laden”.... He spoke of secret suffering, of shame and sorrow, of the redeeming power of the analytic. He advocated the bringing of light into the unconscious mind.”
—Thomas Mann (1875–1955)
“He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll check on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
—Elizabeth Wilson, U.S. crime victim. As quoted in People magazine, p. 88 (May 31, 1993)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
