Abstract
A micro processor based Lighting Control System and Module is disclosed which controls lighting circuits to operate at reduced power levels to obtain the most efficient lighting level for a given task to obtain conservation of energy and a financial savings. After the control is set by the user for a selected lighting level reduction, a selected power is applied; and, the system, through its micro processor and control circuitry, continuously monitors the power applied, and maintains a desired power level to maintain the lighting level desired.
