In one aspect of the invention the A/C ratio of the conic section solids are varied to collimate the light emitted in the vertical direction and spread light in the horizontal direction. In another aspect of the invention the A/C ratio of a hyperbolic conic section may remain the same while adding fluting to the outer surface of the lens to provide beam redirection.
