LRC Releases New Version of Circadian Stimulus Calculator with Expanded Functionality

LRC

The Lighting Research Center has released a new version of its free, open-access circadian stimulus (CS) calculator with more robust and flexible functionality to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces. 

The new calculator provides additional functions not included in the original version, including the ability to calculate CS levels in rooms with multiple light sources; and combine pre-loaded SPDs from the calculator dropdown and user-supplied SPDs to provide one CS measurement and a single relative SPD.

Lighting professionals can use the CS calculator to compare the effectiveness of various light sources for stimulating the circadian system. The CS calculator utilizes the CS metric, a measure of how one-hour exposure to a light source of a certain SPD and light level stimulates the human circadian system, as measured by acute melatonin suppression.
