IMPROVED REFLECTOR LAMP ABSTRACT OF THE DISCLOSURE A reflector lamp has a concave reflector having a parabolic rear section, a spherical intermediate section and a faceted parabolic front section, the three sections having substantially the same focal point. A finite light source is located at the common focal point. The reflector sections are dimensioned so that sub- stantially all light rays from the light source which are reflected by the spherical intermediate section become re-reflected by the faceted parabolic front section. Additionally, the light rays reflected by the facets include components thereof which are cir- cumferential about the central lamp axis and thereby provide a beam pattern which is substantially cir- cumferentially uniform about the lamp axis.
