This chapter is intended to establish standards to provide for properly designed and installed outdoor lighting. It is intended to reduce or eliminate problems of glare, minimize light trespass into public spaces and private property, promote energy conservation, protect the nighttime character of the desert sky, and help reduce the energy and financial costs of outdoor lighting by establishing regulations which limit the area that certain kinds of outdoor-lighting fixtures can illuminate.
