Summary
This paper establishes minimum reporting standards for light exposure in chronobiology and sleep research, requiring documentation of spectral power distributions, α-opic irradiances, illuminance, timing, and spatial properties of light stimuli. For lighting designers and researchers, these guidelines provide a practical framework for ensuring reproducibility and comparability of studies investigating non-visual light effects.
Key Findings
- Seven minimum reporting requirements identified: (i) spectral power distribution of acute stimulus, (ii) spectral power distribution of background, (iii) tabulated spectra, (iv) α-opic irradiances and illuminance, (v) timing properties, (vi) spatial properties, and (vii) measurement conditions and equipment.
- Guidelines reflect state-of-the-art knowledge as of June 2019 regarding non-visual light sensitivity, including established action spectra for melatonin suppression.
- Authors note that while key aspects of non-visual light sensitivity (e.g., melatonin suppression action spectrum) are characterized, significant gaps remain, underlining the importance of standardized reporting for cumulative scientific progress.
