This 2021 report by Luminus Devices, Inc. from 2021 examines human-centric lighting (HCL), a decades-old concept that now through scientific and LED technology advancements is supported by more sophisticated approaches not previously seen. The analysis highlights that creating basic HCL schemes requires selecting fixtures with the appropriate color temperature and brightness that reach circadian standard targets while optimizing for human productivity, comfort, and rest. The report outlines what “healthful light” means and discusses the role of existing standards such as the WELL Building Standard, which provides an evidence-based system for calculating healthful light.
