Claim Text:
1. A lighting device comprising: a plurality of light sources and at least a first group of solid state light emitters, each of the light sources comprising at least one of a second group of solid state light emitters, at least one of the first group of solid state light emitters and at least one of the second group of solid state light emitters on a first string, at least one of the first group of solid state light emitters and at least one of the second group of solid state light emitters on a second string, the first string electrically parallel to the second string, each light source, when illuminated, emits light which, in an absence of any additional light, has x, y color coordinates which define a point which is within a first area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point, and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.32, 0.40, the second point having x, y coordinates of 0.36, 0.48, the third point having x, y coordinates of 0.43, 0.45, the fourth point having x, y coordinates of 0.42, 0.42, and the fifth point having x, y coordinates of 0.36, 0.38, each of the first group of light emitters, when illuminated, emitting light having a dominant emission wavelength in the range of from about 602 nm to about 615 nm, wherein:
