ABSTRACT:
A track lighting system which uses a lighting truss which separates the support function from the electrical connection function is provided. A lighting truss is shown which consists of a longitudinally extending base portion having at least an upstanding flange projecting from one side, and an upstanding wall projecting from the other side. A piece of lighting track is mounted on the vertical wall portion, and a beam clamp fastens a luminaire to the longitudinally extending base portion. The upstanding flange will prevent the luminaire from falling off should it loosen in use.
