Table 2 Melanopic equivalent daylight illuminance (mEDI) and photopic illuminance (lux) obtained from the standard lamp spectra (Fig. 1A–E) using Eq. (14) (implementation of the Irradiance Toolbox supplement to Lucas et al.18). Values in parentheses are minimum and maximum.
From: Home lighting, blue-light filtering, and their effects on melatonin suppression
