Abstract
A display lighting system is provided that assembles and installs easily and provides a wireway for luminaire and other types of wiring. Luminaires of the system each include a lamp housing attached to the ends of a pair of arms that can hold the housing sufficiently out beyond a displayed object to provide more complete illumination of the object'"'"'s vertical face. Each luminaire includes a wireway enclosure dimensioned to enclose electrical wiring and at least one electrical component, such as a ballast or transformer. The enclosure is positioned between the arms at the ends opposite the lamp housing. Wiring between the lamp housing and enclosure is carried inconspicuously in a trough along the inside of one or both arms. Wiring between adjacent luminaires runs conveniently through nipple connectors connecting adjacent enclosures. Optional uplighting and accent lighting is also provided.
