Abstract
Aspects of the disclosure provide a light with reduced glare and light trespass. The light includes a light source that emits light, a primary optic that at least partially encloses the light source such that at least a portion of the light emitted from the light source passes through the primary optic, and a secondary optic including a portion shaped as a non-spherical frustum. The non-spherical frustum is bounded between first and second parallel planes. The secondary optic is securable relative to the primary optic such that at least a portion of the primary optic is at least partially enclosed by the secondary optic and positioned between the first and second parallel planes.
