ABSTRACT:
A work area lighting system is provided including a housing containing a linear light source therein and having an open bottom end. A refractor comprising a pair of refractor plate members closes the open bottom end. The refractor includes a first member having a plurality of spaced prisms extending parallel to the light source and a second member having a plurality of spaced prisms extending perpendicular to the light source. The second member underlies the first member and is approximately one-half its length. The second member is moveably mounted to the housing to enable it to slide with respect to the first member so that different portions of the first member may be covered as desired.
