Abstract: An improved undershelf elongated task light fixture. The fixture includes an elongated housing means having a top, a front wall depending from the top, and a back wall depending from the top and spaced rearwardly of the front wall. A tubular lamp is positioned in the housing between the front wall and the back wall. An elongated shield having a rearwardly facing, downwardly and rearwardly inclined reflector element is mounted on the housing. The shield lies beneath, and extends forwardly of, the tubular lamp. The housing and shield define an elongated opening adjacent the base of the housing between the front wall and the tubular lamp. A light diffuser, such as a batwing diffuser, covers the opening. The elongated shield substantially blocks direct radiation from the tubular lamp from impinging on the light diffuser, hence prevents veiling reflections almost entirely.
