Abstract

Abstract An improved source light for cameramen, lighting technicians, for set lighting for motion pictures, stage, television and the like. The source light has a vented body containing at least three lamps, each lamp having a halogen cycle bulb held in a reflector which emits a directed beam of light. Each of the reflectors has a generally planar face and all the reflectors are mounted so that their generally planar faces lie in a single plane. A lens means is held adjacent that single plane. Preferably, the lens means is a flat lens which also serves to hold the lamps in place.
