Abstract: Light emitting devices include a first string of LEDs that emit light having a color point that is within at least eight MacAdam ellipses of a first blue-shifted-yellow region on the 1931 CIE Chromaticity Diagram, a second string of LEDs that emit light having color point that is within at least eight MacAdam ellipses of a second blue-shifted-green region on the 1931 CIE Chromaticity Diagram, and a third light source that emits radiation having a dominant wavelength between 600 and 720 nm. A drive circuit supplies respective drive currents to the first string of LEDs, the second string of LEDs and the third light source, at least two of which are independently controllable.
