A luminaire includes a plurality of light modules that have a light source at one end, an exit aperture at the other end, and a light source cover. A first baffle forms sides of first shielding compartments that correspond to the light modules. A light shield that includes a plurality of shield apertures that correspond to the plurality of light modules. Each shield aperture fits around a corresponding light module. The light shield is mounted on a proximal end of the first baffle and the exit aperture of each light module is located in a corresponding first shielding compartment. The light shield is configured to reduce light spill from the first shielding compartments toward the proximal ends of the light modules. The luminaire also includes a plurality of output lenses that correspond to the plurality of first shielding compartments. The output lenses are coupled to a distal end of the first baffle and the edges of each lens are coated with a light absorbing coating. The luminaire further includes a second baffle that forms sides of a plurality of second shielding compartments that correspond to the plurality of output lenses. A proximal end of the second baffle couples to the output lenses.
