Abstract
Abstract A high intensity discharge light fixture is provided wherein the conventional gaskets are replaced by joints which prevent water from entering the fixture but permit free air flow. The joints are formed by components, at least one of which terminates in a U-shaped section and the other of which interdigitates with the U-shaped section. The leg of the U-shaped section directed toward the fixture interior is longer than the leg directed away from the fixture thereby providing a water barrier.
