Abstract
A light fixture includes a housing having a top wall and a front wall. An upright lip on the housing projects up above the top wall generally adjacent the front wall. Fasteners mount at least one lamp on the housing forward of the front wall. A light diffuser is further provided including a hollow shell having a back with an opening therein to permit entry of the lamp and the housing lip into the shell as the diffuser is installed on the housing. When the diffuser is installed on the housing, the lip extends up on the inside of the shell closely adjacent an interior surface of the shell above the opening. The lip and interior surface of the shell are engagable to hold the diffuser on the housing, without the need for mechanical fasteners, in a position in which the diffuser shell is suspended on the housing with the back of the diffuser shell in close, generally abutting relation with the front wall of the housing.
