Claim:
1. An LED light fixture comprising: two major principal axes in a fixture plane, the dimensions of the fixture in planes parallel to its third principal axis being substantially smaller than the largest dimensions parallel to the fixture plane; a first outer side having a first central portion; an opposite second outer side having a second central portion substantially aligned with the first central portion and encompassing a light-emitting region open to air and water flow and including at least one LED-array module supported by an LED heat sink; and a perimetrical structure forming a closed chamber which fully surrounds the light-emitting region and encloses at least one electronic LED driver, the perimetrical structure having first and second edge-adjacent portions meeting at a perimetrical edge and each having a boundary with the respective one of the first and second central portions, the first and second edge-adjacent portions converging toward each other at positions progressively closer to the perimetrical edge, thereby forming aerodynamic-drag-reducing cross-sectional profiles transverse to the fixture plane and extending in substantially all fixture-plane directions from the intersection of its two major principal axes.
