A mobile, variable effect lighting device including a mobile base platform to which is mounted an adjustably positionable and extendable boom. A lighting array frame having one or more luminaire assembly units is hingeably mounted to the outer end of the boom. Each luminaire assembly unit, in turn, is individually vertically and horizontally adjustable. Appropriate motor or power mechanisms are operably connected to the luminaire assembly units, the lighting array frame, and the boom to allow automatic and remote adjustability and operation of these components. A control circuitry is operatively connected to the luminaire assembly units and the motor or power mechanisms and has a control unit by which a remote operator can control operation of luminaire assembly units, and their orientation with respect to a target area.
