A luminaire for lighting an area includes at least one LED and a first reflector disposed substantially within the housing. The first reflector includes an annular reflective surface having a central axis and an edge defining an aperture through which light exits. The annular surface is formed from a first conic cross section portion revolved about the central axis with one of the at least one LED facing the central axis and positioned proximate a focal point of the first conic cross section portion. The luminaire also includes a second reflector within the housing. The second reflector has a bottom reflective surface that is formed from a second conic cross section portion extending to and revolved about the central axis. The focal point of the second conic cross section portion is proximate the one of the at least one LED.
