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:
“If the street life, not the Whitechapel street life, but that of the common but so-called respectable part of town is in any city more gloomy, more ugly, more grimy, more cruel than in London, I certainly dont care to see it. Sometimes it occurs to one that possibly all the failures of this generation, the world over, have been suddenly swept into London, for the streets are a restless, breathing, malodorous pageant of the seedy of all nations.”
—Willa Cather (18761947)
“I light matches and put them in my mouth,
and my teeth melt but the greenery hisses on.
I drink blood from my wrists
and the green slips out like a bracelet.
Couldnt one of my keepers get a lawn mower
and chop it down if I turned inside out for an hour?”
—Anne Sexton (19281974)
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been Let every man look out for himself, let every generation look out for itself, while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (18561924)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (18871948)
