1. An LED floodlight fixture having its two major principal axes in a fixture plane, the dimensions parallel to its third principal axis being substantially smaller than the largest dimensions parallel to the fixture plane, the fixture characterized by:

  • a first outer surface having a first central portion and a first edge-adjacent portion;

    an opposite second outer surface having (a) a second central portion substantially aligned with the first central portion and encompassing a light-emitting region and (b) a second edge-adjacent portion having a boundary with the second central portion such boundary defining a reference plane, the first and second edge-adjacent portions meeting at a perimetrical edge;

    the first and second central portions each extending across at least 25% of the area within the perimetrical edge;

    the first and second edge-adjacent portions forming aerodynamic-drag-reducing cross-sectional profiles transverse to the fixture plane and extending in substantially all in-fixture-plane directions and having aspect ratios of about 3 or less; and

    the greatest dimension between the first central portion and the reference plane is no more than 50% greater than the smallest dimension therebetween.
