A variable light modifier provides rapid beam deflection and flipping with a minimum of noise, power consumption and heat generation. In one embodiment of the invention, a dual-sided reflector is pivotable along orthogonal axes by pan and tilt mechanisms. The pan and tilt mechanisms are driven by pan and tilt motors, one or both of which remain stationary with respect to the yoke. The variable light modifier can be used to deflect light beams generated by one or more light sources and can reflect the light from one or both reflective surfaces of the reflector.

Variable light modifier

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.
