A task light panel for use with a light source for illuminating a work surface. The panel comprises an upper surface having a plurality of transverse grooves formed thereon and a lower surface having a plurality of longitudinal grooves formed thereon. The transverse and longitudinal grooves are substantially perpendicular to each other and are adapted to distribute light from the light source onto the work surface, reduce glare or veiling reflections from the work surface, and block direct viewing of the light source by an individual using the work surface.
