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. |
