Abstract
Embodiments described herein provide systems and methods for promoting plant growth that combine beam angle control with spectral control. In one embodiment, an optical device can be configured to emit multiple colors of light at particular wavelengths. The optical device may also be configured to generate an emission spectrum with multiple peaks. The spectrum can be selected based on stimulating biological processes of a plant.
