Abstract
Disclosed herein are lighting apparatuses that have an oblong optic that corresponds to a plurality of light sources. According to certain embodiments, a lighting apparatus includes a plurality of light sources that are arranged along a linear direction, and an optic that is configured to receive light from each light source of the plurality of light sources. The optic has an oblong shape with a long axis that is parallel to the linear direction, and the optic is configured to emit an output light beam that is substantially rotationally symmetric in a plane that is orthogonal to an emission direction of the plurality of light sources.
