A lighting assembly is provided that is configured for use with a hydroponic farm, preferably a hydroponic farm utilizing horizontal racks. The light assembly includes one or more LED boards affixed to a thermally conductive mounting fixture. The number and location of the LED boards which are mounted to the fixture is primarily dependent upon the size and layout of the hydroponic racks within the hydroponic farming facility. A light shield, which surrounds the LED boards and the mounting fixture, extends the entire length of the light assembly. The light shield is sealed to both light assembly end caps, thereby providing a completely sealed lighting unit.
