Spectral irradiances of the ambient and task lighting (top), ambient and task combined lightings (middle), and their melanopsin-stimulating fractions (bottom). The melanopsin-stimulating spectral irradiance was calculated from the melanoptic spectral efficiency curve (dotted line in the middle panel) adjusted for the effect of human pre-receptoral filtering [15, 32, 33]
