Intelligent Lights (aka. Moving lights or automated lights) are lights that are able to adjust their focus on the fly without having to be focused into a particular position. Typically they can move to shine their beam in almost any conceivable direction and also have color controls that allow them to change the beams color on the fly. They are able to replace several traditional non moving lights and can achieve a variety of effects. While they are programmed to follow simple movement commands they can be operated live by a sufficiently skilled operator
These lights are capable of truly remarkable effects and can add a lot to the quality of a show. They receive their information through DMX that is connected through the lighting console. The DMX sends information between the lighting console and the light and adjusts it's values for it's pitch, tilt, rotation, etc.
