1. A light emitting diode lighting fixture comprising:
- an elongated fixture base having a trough including an inwardly oriented flange;
a printed circuit board mounted in the fixture base;
a plurality of light emitting diodes linearly mounted on the printed circuit board; and
a plurality of bezels, each bezel having a plurality of lenses, a single lens for each light emitting diode, the inwardly oriented flange configured to slidably and removably engage the plurality of bezels mounted to said base by the inwardly oriented flange, wherein the printed circuit board is disposed between the fixture base and the bezelwherein the plurality of lenses are chosen from a plurality of lens types to direct light into light output pattern characterized by a specific illumination footprint, and wherein the light output pattern is reconfigurable by exchanging at least one of the plurality of lenses with a lens of another type individually.
