Abstract
A light assembly includes a cover, a base and a housing coupled between the housing and the base. A first circuit board is disposed within the housing. The first circuit board has a plurality of light sources thereon. The housing comprises an inner wall defining a first volume therein and an outer wall spaced apart from the inner wall. The housing comprises a plurality of spaced apart fins extending between the inner wall and the outer wall define a plurality of channels having a first end proximate the cover and a second end proximate the base. The channels have a first cross sectional area proximate the first end greater than a second cross-sectional area proximate the second end. An elongated control circuit board assembly is electrically coupled to the light sources of the first circuit.
