You are looking at a vintage NESS Mercury DJ / Nightclub / Disco lighting unit.  These were very common in the 90's and it is built like a tank!  This unit is simalar to the American DJ Aggressor / Lampo Apollo units but also features a direct input for the audio source that makes the beams move to the beat of the music.  It also works like a standard stand alone unit where the ambiant sound triggers the lights motion.  Unit works great and 2 new lamps have been installed.  Since the lamps are fragile we are not responsable if they do not make it through shipping.  We can remove and pack them in the unit upon request.
