Scotopic vs photopic lumens

Photometric measurements are performed using apparatus that is designed to spectrally match the daylight adapted response of the eye, this being the CIE photopic observer function which peaks at 555nm (green). This applies when the source luminance is above 3cd/m2. However, when the eye is fully dark adapted, the photopic response no longer applies - instead the eye adopts the scotopic response which peaks at 507nm (blue/green). The scotopic response applies when luminance is less than 0.01cd/m2. Human vision.
