Solid state lighting devices including multiple solid state light emitters are arranged to produce a mixture of light having a color rendering index (CRI Ra) value of at least 80, having a gamut area index (GAI) value in a range of from 80 to 100, and x, y coordinates within a predefined region of a 1931 CIE Chromaticity diagram, e.g. including x, y coordinates defining point on or within a first polygon bounded by the following x, y coordinates: (0.38, 0.34), (0.38, 0.36), (0.40, 0.38), (0.42, 0.38), (0.44, 0.36), (0.46, 0.36), and (0.46, 0.34). In certain embodiments, a lighting device includes a primary emitter having a dominant wavelength in a range of from 430 to 480 nm, a lumiphor having a dominant wavelength in a range of from 535 to 585 nm, and a supplemental emitter having a dominant wavelength in a range of from 590 to 650 nm.
