N1 - Funding Information:
This project was partially supported by the EISG program of the California Energy Commission grant number 52737A/01–25. We are grateful to Paul Duane from Litecontrol for donating the custom luminaires, and William Jackson and William Beers from General Electric for their phosphor expertise and for donating the prototype fluorescent lamps. We thank Brent Protzman and Toby Samuelson for assisting with the set-up of the research apparatus and for administering the experiments; their involvement was supported by the Under- graduate Creative Activities and Research Experiences (UCARE) program of the University of Nebraska-Lincoln. Xin Hu was partially supported by the American Public Power Association through the Demonstration of Energy Efficient Developments (DEED) program, and was partially supported by the University of Nebraska’s Center for Building Integration (CBI). The CBI also provided funding for equipment and materials. We thank the IESNA Quality of the Visual Environment Committee and IALD Metrics of Quality Committee for participating as expert subjects. Finally, we thank William Thornton and Stephen Fotios for their thoughtful reviews of an early version of this manuscript.

N2 - 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.
