Abstract
A light fixture includes a lampholder mounted to a raceway, where the lampholder is electrically connected to a lampholder connector. A power pack includes a power pack cover and a ballast. An outer surface of the power pack cover includes an emissive coating such that heat generated by the ballast is emitted from the power pack cover. The ballast is mounted in direct contact with the power pack cover such that the heat generated by the ballast is conducted from the ballast to the power pack cover. The ballast includes a power input connector adapted to electrically connect to a power cord and a ballast output connector adapted to electrically connect to the lampholder connector.
