Programmi Sistemi Luce (PSL) Tremors Lighting Unit

This is a very interesting and unique fixture.  This is the Tremors by PSL.  This unit has 4 large lenses on the front.  Projected from each lens are 6 dual colored beams of light.  This is made by 4 separate sets of 6 dichoric glass pieces mounted in a linear fashion on 4 motors making a total of 24 beams.  Each motor has 2 different colors on each dish.  Opposite (diagonal) motors are wired together and are triggered from the PCB at the rear of the unit.  In addition to the rotating dishes there is another motor with a weight attached to the end that is controlled from a potentiometer on the rear or an optional 0 – 10 volt analogue control source.  This makes a vibrating action which makes the beams shake in addition to the rotation.  The lamp source is a central 120 volt, 600 watt DYS bulb making a very bright output.  Unit made in Italy.
