Vision experiment ii on white light chromaticity for lighting

Abstract

In response to a published discussion (Wei & Houser, 2015) on the 2013 NIST experiment on white light chromaticity for lighting (Ohno & Fein, 2013), the second experiment was conducted at NIST to determine the white light chromaticity perceived most natural in a simulated interior room environment using the NIST Spectrally Tunable Lighting Facility. The 2015 experiment was conducted with 21 subjects, for shift of Duv (chromaticity shifts above and below the Planckian locus), using the same procedures as the 2013 experiment but minimizing the changes in gamut area in each pair of lights compared so that only the effects of chromaticity would be evaluated. The results showed that the lights with Duv ≈ -0.015 on the average, nearly the same as the results in 2013, appeared the most natural at all correlated color temperatures.
