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.

“But seldom the laurel wreath is seen
Unmixed with pensive pansies dark;
There’s a light and a shadow on every man
Who at last attains his lifted mark—
Nursing through night the ethereal spark.
Elate he never can be;
He feels that spirits which glad had hailed his worth,
Sleep in oblivion.—The shark
Glides white through the phosphorus sea.”
—Herman Melville (1819–1891)

—Ursula K. Le Guin (b. 1929)
“I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
