Abstract: A lighting fixture comprises a housing, an induction lamp inside the housing, a lens disposed to direct light away from the housing in a light pattern, and a light reflector inside the housing which reflects light in cooperation with the lens. The light pattern produced by the lighting fixture has a substantially uniform lateral illumination at a given radial distance from the center of the lens. The lighting fixture also provides a high level of directional illumination in the vertical direction when mounted to a ceiling. The lighting fixture can be surface or recess mounted. The lighting fixture can comprise a tee electrical conduit to allow through feed wiring from one fixture to another fixture. The lighting fixture is particularly suitable for use in conventional walk-in coolers and freezers used in supermarkets.

Abstract: A lighting fixture has (i) a base, (ii) a support on the base, the support electrically connecting to the fixture, (iii) a light-transmitting cover, removably supported by the base, (iv) end caps covering the open ends of the base, and (v) means for securing the end caps to the base so that the cover can be removed from the base without removing the end caps. This provides easy access to a light for replacement of the light without the need for any tools.
