A lighting device includes a first LED configured to emit a first light, a second LED configured to emit a third light, a first phosphor disposed over the first LED and second LED, and arranged to absorb a portion of the first light and in response emit a second light of a longer wavelength than the first light, and a second phosphor disposed over the second LED, the second phosphor arranged to absorb a portion of the third light and in response emit a fourth light of a longer wavelength than the third light, and the fourth light exits the second phosphor into the first phosphor, and both the second light and fourth light exit the lighting device though the first phosphor.
