Abstract
A light fixture includes a first phosphor-converted light-emitting diode ('PCLED') emitting light in a first PCLED wavelength range having first PCLED upper and lower bounds, a first direct light-emitting diode ('DLED') emitting light in a first DLED wavelength range having first DLED upper and lower bounds, a second PCLED emitting light in a second PCLED wavelength range having second PCLED upper and lower bounds, and a second DLED emitting light in a second DLED wavelength range having second DLED upper and lower bounds. The first PCLED upper bound has a higher wavelength value than the first DLED upper bound. The first PCLED lower bound has a lower wavelength value than the first DLED lower bound. The second PCLED upper bound has a higher wavelength value than the second DLED upper bound. The second PCLED lower bound has a lower wavelength value than the second DLED lower bound.
