Abstract
A lighting truss utilizes a drive assembly to facilitate movement of lighting instruments between a protected transport position and a deployed position, extending the lighting instruments below the truss for operation. Once deployed, means are provided for spreading the lighting instruments apart from one another to allow unimpeded pan and tilt operation of the lighting instruments and allow for storage of the lighting instruments in a relatively small truss.
