Claim:
1. A method operating a light-emitting system to emit light, said light-emitting system comprising at least one light emitting diode (LED), said method comprises: driving said at least one LED with a current density of at least 40 A/cm wherein said first radiation is optically coupled to a first at least one wavelength conversion material and a second at least one wavelength conversion material, wherein said first at least one wavelength conversion material is configured to convert at least a portion of said first radiation to a second radiation characterized by a second peak wavelength in a second range from about 500 nm to about 600 nm, and said second at least one wavelength conversion material is configured to convert at least a portion of said first radiation to a third radiation characterized by a third peak wavelength in a third range from about 600 nm to about 700 nm; and wherein said emitted light is based on said first radiation, said second radiation, and said third radiation, and characterized by a spectral power distribution (SPD), and wherein a fraction of said SPD is between about 2% and about 25% in a fourth range from about 390 nm to about 430 nm.
