This work comprised a technical comparison of the LED spectra to daylight spectra, a literature review addressing the effect of light spectra on humans, and a psychological study (between-subjects design) including subjective rating and performance tests with 83 persons in an office setting. Each participant was tested for one hour in one out of 4 lighting settings comparing Full Spectrum LEDs with conventional LEDs covering various aspects like visual comfort, naturalness, concentration, general glare rating, sleepiness, alertness and glossiness.
