1. A horticulture grow light comprising:
a first plurality of white light emitting diodes (LEDs) having a first color temperature less than or equal to 3500 Kelvin (K);
a second plurality of white LEDs having a second color temperature greater than or equal to 5000 K;
a plurality of supplemental radiation emitters configured to emit light in a wavelength range of 620 nm to 780 nm; and
a driver configured to supply a current to the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters to provide an overall spectral composition,
wherein the overall spectral composition of radiant energy collectively emitted at a same time by the first plurality of white LEDs, the second plurality of white LEDs, and the supplemental radiation emitters has a peak wavelength in a range from 400 nm to 510 nm and a peak wavelength in a range from 560 nm to 780 nm.
