Abstract of the Disclosure, A reflector lamp with a shaped reflector and lens. The reflector is generally parabolic to reflect, light frontwardly. Some of the direct light from the light source is not reflected, and diverges in a beam pattern that would be wasted; the lens refracts this divergent light in a more frontwardly and useful direction. For a flood light, the lens converges the reflected light rays into a cross-over pattern to provide a flood beam pattern. ', . .
