A light assembly comprising:
- an elongated housing;
- a reflective parabolic cylindrical surface within the elongated housing having a focal line;
- an elongated cover coupled to the elongated housing;
- and
- a plurality of light-emitting diodes spaced apart longitudinally along the focal line and emit light toward the parabolic cylindrical surface away from the elongated cover;
- said reflective parabolic cylindrical surface reflecting light from the light-emitting diodes out of the housing and through the cover, wherein the light reflected from the parabolic cylindrical surface is collimated in a radial direction and diffuses in a longitudinal direction.
