The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently released a free, open-access circadian stimulus calculator to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces. The metric is a new way to quantify light’s impact on acute melatonin suppression, a marker of circadian system activation.
The recently published paper, “Light as a circadian stimulus for architectural lighting,” details how the model works and how it can be used to predict effectiveness of various light sources for stimulating the human circadian system.
