Self-standing reflector for a luminaire

A method of illuminating an area with an energy-efficient, light-directing reflector luminaire, using less power than with a conventional reflector luminaire, comprising the steps of:

• 5) providing a luminaire having a conventional reflector having an inner reflective surface having a reflectance of less than 95% (less than Miro-4), which emits a reference amount of lumens in a circular pattern from a first lamp of X Watts, for illuminating a rectangular target area with a minimum illuminance;
• 6) providing an energy-efficient, light-directing reflector comprising a main reflector comprising a plurality of reflector panels forming an inner reflective surface, the plurality of reflector panels including a pair of first reflector panels disposed on opposite sides of the main reflector and a pair of second reflector panels disposed on opposite sides of the main reflector and being perpendicular to the first reflector panels, and a plurality of reflective inserts joined to the interior surface of the main reflector and having a reflecting surface disposed away from the interior reflective surface of the main reflector, the plurality of reflective inserts including a pair of opposed first reflective inserts, each joined to and disposed inboard from one of the first reflector panels and a pair of opposed second reflective inserts, each joined to and disposed inboard from one of the second reflector panels, wherein the surfaces of the reflector panels and the reflecting surfaces of the reflective inserts have a reflectance of at least 95%;
• 7) providing a second lamp of about 0.7X to 0.95X Watts;
• and
• 8) replacing the conventional reflector with the energy-efficient, light directing reflector, and replacing the first lamp with the second lamp, and illuminating the rectangular target area,
• wherein the rectangular target area is uniformly illuminated with at least the minimum illuminance.
