Abstract

Results of a pilot study are presented that explored the hypotheses that brightness and color perception would be enhanced by increasing the proportion of spectral content within, the 450-530-610 nm. regions. Expert, and naïve subjects completed a forced, choice task, comparing pairs of offices illuminated at 538 lx (50 fc) with one of four different prototype lamps that varied in spectral content in the 450-530-610 nm regions. Rooms illuminated with lamps having a higher percentage of their spectral power in these regions were perceived as brighter and more colorful Expert, and naïve observers had similar responses but. the experts expressed, their opinions more definitively. These data suggest that the perception of brightness, color, and visual, clarity are more reliant upon the placement of radiant power within key spectral regions, rather than on the magnitude of the energy within those regions. These results cannot be explained with the S/P ratio.
