Abstract
The present invention is a hazardous location induction lighting fixture. The light fixture has a tank having a base with parametrically side walls terminating at a rim to define the interior portion. The interior portion further includes at least one tank extension extending from the base to support a ballast plate. A ballast plate is used as a heat sink to which a induction light assembly is attached. The induction light assembly is electrically connected to an induction lamp which is positioned on the outer of the tank to emit light. A refractor assembly is selectively securable to the tank to enclose the induction lamp and in a preferred embodiment can be sealably secured to the tank to prevent fluids or dusts from entering the lamp.
