Title The effect of two lamps with the same colour temperature, but with different spectra, on mental performance and on certain physiological functions
Original title Über den Einfluss zweier Lampen mit gleicher Farbtemperatur, aber verschiedener spektraler Zusammensetzung auf Leistung bei geistiger Arbeit und ausgewählte physiologische Funktionen [in German]
Bibliographic information 1983, Vol.29, No.8, p.467-472. Illus. 21 ref.
Abstract The experiments lasted 1.5h each and involved problem solving in rooms with illuminance levels of 400lx produced either by an incandescent light source (tungsten-halogen lamp) or by a fluorescent source (metal halide lamp), both at a colour temperature of 3,200°K. There was no difference in performance between the two groups, but there was a significant increase in symptoms of physiological stress among subjects exposed to the fluorescent light source. Colour temperatures alone cannot be used as criterion for evaluating the effects of the lamps.
