Abstract: A light-emitting diode (LED) lighting device includes a white light source characterized by a general color rendering index (CRI) value and a first color-specific CRI value, and one or more LED elements of a color light within a wavelength band, wherein a combined light source comprising the white light source and the one or more LED elements is characterized by the general CRI value and a second color-specific CRI value, and the second color-specific CRI value is greater than the first color-specific CRI value.
