Abstract
Lighting fixture having housing with an open side. A lamp is mounted in the housing and is capable of producing light rays which pass through the open side of the housing. A glass protective covering is carried by the housing and encloses the open side. At least one surface of the glass is provided with anti-reflection film formed by a chemical etch/leach process on the one surface. The anti-reflection film increases the transmission of the high angle light rays from the lamp.
