1. A luminaire comprising:
a housing having an interior, the housing separating the interior of the housing from at least a portion of an external environment;
a trespass shield removably coupleable to the housing;
a light source at least partially received in the interior of the housing, the light source operable between at least an ON state in which the light source emits light and an OFF state in which the light source does not emit light;
a primary optic coupled to the housing, the primary optic positioned between the light source and the external environment such that at least a portion of the light emitted from the light source passes through the primary optic; and
a secondary optic removably coupled to the housing, the secondary optic including:
a base portion that includes a first, open end of the secondary optic;
a remainder portion that includes a second, closed end of the secondary optic, the remainder portion extending away from the base portion at a non-zero angle with respect thereto, and the remainder portion having a cross-sectional shape that lies entirely within a reference plane that is parallel to a straight line that extends between the first, open end, and the second, closed end, the cross-sectional shape including at least a first region and a second region, wherein the first region includes a first linear segment or a first curved segment, the second region includes a second linear segment or a second curved segment, and one of:
1) the first linear segment is angularly offset with respect to the second linear segment;
2) the first linear segment is angularly offset with respect to a line that both is tangent to the second linear segment and lies entirely within the reference plane;
3) a line that both is tangent to the first curved segment and lies entirely within the reference plane is angularly offset with respect to the second linear segment; or
4) the first curved segment has a different radius of curvature than a radius of curvature of the second curved segment,
wherein the secondary optic is coupled to the housing such that at least a portion of the primary optic is received within a recess of the secondary optic and at least partially enclosed by the secondary optic, the recess delimited by the base portion and the remainder portion.
