Abstract
A light includes a housing defining a bottom end and a top end, a heat sink disposed within the housing and including a central body that defines a central aperture, and a plurality of arms coupled to the central body and extending outward from the central body, each of the arms including a light receiving surface. A plurality of LEDs is coupled to each of the light receiving surfaces and a hollow tube extends from the bottom of the housing and is coupled to the heat sink to define a cooling air passage that passes through the hollow tube and the central aperture to direct cooling air from the bottom of the housing to the top of the housing.
