Abstract
A grow light includes a plurality of cool white LEDs, a plurality of warm white LEDs, and a driver electrically coupled to the cool white LEDs and the warm white LEDs. An intensity level and spectral composition of the radiant energy emitted by the grow light may be tuned or configured by varying a ratio of the quantity of cool white LEDs to the quantity of warm white LEDs, by varying a spatial arrangement among the cool white LEDs and the warm white LEDs, or by varying a level of current provided to some or all of the cool white LEDs and the warm white LEDs.

A horticulture grow light comprising:
- a first plurality of white LEDs having a color temperature greater than or equal to 4000 Kelvin (K) and configured to emit a first radiant energy;
- a second plurality of white LEDs having a color temperature less than or equal to 3500 K and configured to emit a second radiant energy;
- and
- a driver configured to drive the first plurality of white LEDs and the second plurality of white LEDs,
- wherein, in a first mode, the driver provides a first current level to the first plurality of white LEDs and a second current level to the second plurality of white LEDs such that the first and second radiant energy combine to have a first spectral composition having a first highest peak wavelength in a range from 400 nm to 510 nm and a second highest peak wavelength in a range from 560 nm to 780 nm, and
- wherein, in a second mode, the driver provides a third current level to the first plurality of white LEDs and a fourth current level to the second plurality of white LEDs such that the first and second radiant energy combine to have a second spectral composition having a first highest peak wavelength in a range from 560 nm to 780 nm and a second highest peak wavelength in a range from 400 nm to 510 nm.
