- installing said at least one lighting unit;
activating a clocking device electrically connected to said at least one lighting unit by applying power to said clocking device;
processing a self-calibrated program and retrieving a pre-recorded historical data from memory of a controller unit, said controller unit being electrically coupled to said at least one lighting unit;
sensing ambient light condition and designating a fixed value of illumination emittance of ambient light based on said retrieved pre-recorded historical data;
setting a pre-determined optimum duration set value to said at least one lighting unit based on said pre-recorded historical data;
measuring a first value time duration of said actual illumination emittance of ambient light; and
evaluating a first measured value of illumination emittance of ambient light between lighting on and off times of said at least one lighting unit by said program in real-time.
