1. A method for varying a luminance of a light, comprising:

  • varying an input to the light, the input setting a rate of change in the luminance of the light;

    setting a threshold value for the luminance of the light; and

    adjusting a rate of change of the input when the luminance is below the threshold to adjust the rate of change in the luminance of the light so that there is a break point below the threshold where the rate of change in the luminance changes, wherein the adjustment to the rate of change in the luminance of light is determined by subtracting an input value from the threshold to determine the distance from the threshold and dividing the distance by an adjustment factor.
