1. A system for generating light, the system comprising:
a first light emitting source for emitting blue light defined by a line connecting ccx, ccy color coordinates of an infinity point of a Planckian locus (0.242, 0.24) and (0.12, 0.068), the Planckian locus from 4000K and infinite CCT, a constant CCT line of 4000K, a line of purples, and a spectral locus;
a second light emitting source for emitting red light defined by the spectral locus between a constant CCT line of 1600K and the line of purples, the line of purples, a line connecting ccx, ccy color coordinates (0.61, 0.21) and (0.47, 0.28), and the constant CCT line of 1600K;
a third light emitting source for emitting green light defined by a constant CCT line of 4600K, a Planckian locus between 4600K and 550K, the spectral locus, and a line connecting ccx, ccy color coordinates (0.445, 0.555) and (0.38, 0.505);
a fourth light emitting source for emitting cyan light defined by a line connecting ccx, ccy color coordinates (0.18, 0.55) and (0.27, 0.72), a constant CCT line of 9000K, a Planckian locus between 9000K and 4600K, the constant CCT line of 4600K, and the spectral locus;
a controller for powering the light emitting sources having at least a first mode and a second;
wherein in said first mode, said first, second, and third light emitting sources are powered to emit first white light, and, in said second mode, said first, second, and fourth light emitting sources are powered to emit second white light; and
wherein said first and second white light falls within a 7-step MacAdam ellipse around any point on the black body locus having a correlated color temperature between about 2700K and about 10000K,
wherein a spectral power distribution for said red light is between 0.0% to 14.8% for wavelengths between 380 nm to 420 nm, between 2.1% to 15% for wavelengths between 421 nm to 460 nm, between 2.0% to 6.7% for wavelengths between 461 nm to 500 nm, between 1.4% to 12.2% for wavelengths between 501 nm to 540 nm, between 8.7% to 20.5% for wavelengths between 541 nm to 580 nm, between 48.5% and 102.8% for wavelengths between 581 nm to 620 nm, 100% for wavelengths between 621 nm to 660 nm, between 1.8% to 74.3% for wavelengths between 661 nm to 700 nm, between 0.5% to 29.5% for wavelengths between 701 nm to 740 nm, and between 0.3% to 9.0% for wavelengths between 741 nm to 780 nm.
