Abstract: A lighting device includes a first string of light emitting diodes (LEDs) configured to emit a warm white light having a warm Correlated Color Temperature (CCT). The lighting device further includes a second string of LEDs configured to emit a cool white light having a cool CCT. The lighting device also includes green light LEDs that emit a green light. A flux of the green light is controlled based on a flux of the cool white light or a flux of the warm white light. The flux of the warm white light and the flux of the cool white light change proportionally with respect to each other.
