Home lighting, blue-light filtering, and their effects on melatonin suppression.

ABSTRACT: Evening residential illumination possesses the capacity to impair sleep quality via the suppression of endogenous melatonin production, a process largely driven by short-wavelength (blue) light. In this investigation, we characterized the light emissions from 52 distinct examples across three common lamp technologies: light-emitting diodes (LED), incandescent, and compact fluorescent (CFL) lamps. To estimate the differential circadian impact of these sources, we determined the Melatonin Suppression Value (MSV), melanopic illuminance, and photopic illuminance for each. Our findings reveal that "cool" white LED (median 12.3% MSV) and "cool" white CFL (12.1% MSV) lamps induce considerably greater melatonin suppression than "warm" white LED (3.6%), "warm" white CFL (2.6%), or traditional incan
