  • setting a target dwell luminance of the light; and

    changing the luminance of the light from a current luminance to the target dwell luminance;

    whereinthe operation of changing the luminance of the light from the current luminance to the target dwell luminance occurs during a specific time interval of a breathing curve, the breathing curve ramping up or ramping down the luminance of light;

    whereinthe target dwell luminance being different from a prior dwell luminance; and

    a peak luminance of the breathing curve likewise changes from a first peak luminance value to a second peak luminance value, the first and second peak luminance values having a different luminance.
