WebTable L1: Melanopic Ratio. The Equivalent Melanopic Lux (EML) is a measurement of light's effects on the circadian cycle. This unit Equivalent Melanopic Lux (EML) was proposed by Lucas and others (Lucas et al., "Measuring and using light in the melanopsin age." Trends in Neuroscience, Jan 2014). http://www.healthybuildingres.com/calculations-light/
WebCollectively, our data demonstrate widespread utility of melanopic illuminance as a metric for predicting the circadian impact of environmental illumination. These data therefore provide strong support for the use of melanopic illuminance as the basis for guidelines that seek to regulate light exposure to benefit human health and to inform future lighting design.
