Table A1.

Illuminance, CCT, α-opic irradiances, melanopic efficacy of luminous radiation, melanopic daylight D65 efficancy ratio, and melanopic equivilant daylight D65 illuminance according to CIE S 026/E:2018 [48] in each experimental condition. Measured with the spectrometer UPRtek LED-Meter MK350S at the subjects’ eye position (cornea).
