ABSTRACT:
A portable lighting system which includes a stand having an adjustable effective length which positions lights carried on a frame at a predetermined vertical position with respect to a supporting surface. The frame is releasably secured to the stand and can readily be set up and dismantled for transport in a compact space. Lights carried by the frame include a new and simple technique for attaching the gelatine filter holders, and may be connected to a foot operated control box which includes switches actuated to energize preselected lights or groups of lights. The energized lights or preselected energized lights can be intensity modulated with a foot operated dimmer while leaving the operator's hands free to play a musical instrument.
