moving head lights
Moving lights as the name would suggest are lights which have integral motors to enable their motion as well as other attributes. They are part of the rather generic term Intelligent Lighting. This term covers any stage light that goes beyond a static light. In so much as the lights can produce some fantastic results, they do not have any intellegence of their own, this is down to the opperator!
Today, the vast majority of lighting is controlled using the DMX protocol and moving lights use various channels to control pan, tilt, zoom, focus etc.
