Abstract: A lighting module that modifies a light beam to affect the size and shape and color characteristics of the projected beam includes a light source and a reflector to direct the light along an optic path. The reflector is formed so that light is directed along a light path that is not parallel to a center line of the reflector. A primary lens element reduces the cross section of an effected light region as the light enters a modifying element area in the optic path. Light modifying elements are deployed in varying combinations and to varying degrees to produce the shape, size, and color of light beam desired by the user. The construction of the light modifying elements allows the elements to be physically positioned in the optic path but to have no effect on the light until the elements are rotated so that light modifying element segments align with lens segments of the primary optical element, and the light modifying element or elements change the light being projected from the lighting module.
