A post-top luminaire assembly directs light generally downwardly from a light source. A first portion of the light output from the light source also forms a first portion of the primary beam. A first reflector portion receives emitted light from the source and redirects a second portion of the light along a second angular range in conjunction with forming the primary beam with the first portion of light. A second reflector portion receives a third portion of the emitted light and redirects it along a third angular range particularly near the pole base, while a third reflector portion receives a fourth portion of the emitted light from the light source and redirects it along a fourth angular range. The second reflector portion provides for light around the lamp base, while the third reflector portion precludes light from passing directly for up-lighting purposes and directs it outwardly at a high angle.
