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.

Even though it be the lightest of light love,
But dreams that hurry from beyond the world
To make low laughter more than meat and drink,
Though it but set us sighing?”

“... the black girls didnt get these pills because their black ministers were up on the pulpit saying that birth control pills were black genocide. What Im saying is that black men have exploited black women.... They didnt want them to have any choice about their reproductive health. And if you cant control your reproduction, you cant control your life.”
—Joycelyn Elders (b. 1933)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Grays Anatomy.”
