1. An optical system for facilitating plant growth, comprising:
one or more light sources operable to produce a light beam having a full width at half-maximum (FWHM) angle of at least one hundred twenty degrees(120°) in a first transverse direction and a FWHM angle of less than one hundred twenty degrees(120°) in a second transverse direction substantially perpendicular to the first transverse direction;
wherein the at least one transverse direction is perpendicular to an optical axis of the light beam.
