From: Home lighting, blue-light filtering, and their effects on melatonin suppression
Melatonin suppression values normalized (MSV⁽ⁿ⁾, %) for (A) the five standard lamp categories and (B) the tunable LED lamps. Panel (A) shows median and range values for incandescent, warm-CFL, warm-LED, cool-LED, and cool-CFL lamps, while panel (B) illustrates the relationship between MSV⁽ⁿ⁾ and correlated color temperature (CCT) for the four tunable LED models (Estevez, Wiz, Philips: hue-color, and Philips: scene-switching).
