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.

Famous quotes containing the words street, light, control and/or systems:
“What are you now? If we could touch one another,
if these our separate entities could come to grips,
clenched like a Chinese puzzle . . . yesterday
I stood in a crowded street that was live with people,
and no one spoke a word, and the morning shone.
Everyone silent, moving. . . . Take my hand. Speak to me.”
—Muriel Rukeyser (1913–1980)
“The light struggled in through windows of oiled paper, but they read the word of God by it.”
—Ralph Waldo Emerson (1803–1882)
“We as a nation need to be reeducated about the necessary and sufficient conditions for making human beings human. We need to be reeducated not as parents—but as workers, neighbors, and friends; and as members of the organizations, committees, boards—and, especially, the informal networks that control our social institutions and thereby determine the conditions of life for our families and their children.”
—Urie Bronfenbrenner (b. 1917)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
