1. An edge-lit luminaire comprising:
a housing having a top and a bottom opening at least partially defining a cavity;
a non-planar lens coupled to the housing that defines a generally circular footprint and a concavo-convex shape, the lens being formed from multiple discrete sections;
a light emitter positioned proximate an edge of the cavity, the light emitter oriented substantially parallel to the bottom opening and configured to emit light into an edge of the lens and toward a center of the cavity; and
a reflector coupled to the housing between the top of the housing and the lens, the reflector configured to direct light emitted toward the cavity back into the lens,
wherein at least a portion of the light emitted into the edge of the lens is redirected inside of the lens and emitted in a direction non-parallel to the bottom opening.
