Fig 7. Theoretical melatonin suppression (according to Rea et al. 2010 model) for absorptive (solid lines) and transmissive (dashed lines) states filtering light spectra for: (A) 5700 (blue diamonds) and 3000 K (orange squares) LEDs, (B) fluorescent (blue triangles), incandescent (orange circles) and mercury vapor (green crosses) light sources, (C) RGB (blue circles) and RGV (purple triangles) LEDs, and (C) Sun light (blue circle) and amber LED (orange triangle).

CS Index is equivalent to melatonin suppression (in %, thus a 0.5 indicates a 50% suppression).
