A lighting device comprising first and second groups of non-white light sources emitting light outside a first area on a 1976 CIE Chromaticity Diagram bounded by a curves 0.01 u′v′above and below the blackbody locus and within a second area enclosed by saturated light curves from 430 to 465 nm and from 560 to 580 nm and segments from 465 to 560 nm and from 580 to 430 nm and a supplemental light emitter in the range of 600 to 640 nm. Also, a lighting device, comprising a first string of non-white phosphor converted light sources with excitation sources having dominant wavelengths that differ by at least 5 nm, a second string of non-white light sources, and a third string of supplemental light emitters in the range of 600 to 640 nm.
