Abstract

A light fixture and wireway assembly is provided in a low-profile configuration wherein at least a portion of a plurality of wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine. In one configuration, at least portions of two to four individual wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine powered by an LED power supply also disposed within the outer perimeter of the overall assembly. Each wireway can be accessed through a single wireway wall without requiring conduit outside of the outer perimeter of the assembly.
