A solid state lighting device includes multiple solid state light emitters and a control circuit configured to adjust aggregated emissions to produce a mixture of light having an adjustable color point together with high luminous efficacy, wherein at least one color point is on or near the white body line WBL (line of minimum tint). Adjustment of color point may provide substantially constant 1931 CIE x-values; substantially constant 1931 CIE y-values, or substantially constant distance relative to the blackbody locus (e.g., with variation in CCT of at least 100K for the color points). An adjustable color point may be arranged to transition between one point near the BBL and another point on or near the WBL. An adjustable color point may provide a first color point on or near the WBL and another point having different CCT and luminous flux. Emitters selected solely from discrete bins or subregions of a CIE diagram may be used in combination to yield a point on or near the WBL.
