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.

“The inability to control our childrens behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. Thats what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
“People stress the violence. Thats the smallest part of it. Football is brutal only from a distance. In the middle of it theres a calm, a tranquility. The players accept pain. Theres a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, theres a satisfaction to the game that cant be duplicated. Theres a harmony.”
—Don Delillo (b. 1926)
