American DJ Spiral Graph

Great and unique lighting unit from American DJ!  This is the Spiral Graph unit that features 1 standard 12 volt, 50 watt EXN MR16 lamp as the light source.  The beam projects through a constantly rotating colored glass wheel that is also textured.  The output is a very cool kaleidoscope image / effect that constantly changes,  The front lens slides in and out to vary the effect and also focuses the beam.  Great compact unit made in China.    

American DJ Colorscope

Very unique lighting effect from American DJ!  This is the Colorscope which makes a hypnotizing effect similar to the older Optikentitics projector units.  The unit features a 24 volt, 250 watt ELC lamp as the light source in the unit.  The beam of light goes through a large focusing lens then through a sound active rotating cylinder with dichoric glass pieces making the color change effect.  As the cylinder rotates there is a large metal gobo that makes the unique effect.  If a different effect is preferred the gobo can be changed out.  Unit is fan cooled and has an adjustment knob on the rear for the sound trigger sensitivity.  Great unit made in Taiwan. 

American DJ Megadroid HMI 575

Gigantic Centerpiece from American DJ.  This is the Megadoid HMI 575 centerpiece unit.  It is by far HUGE to say the least!  This is the clone of the Griven Helios unit.  The unit has a central HMI 575 discharge bulb in the base of the unit producing a great amount of light.  The light shoots out of 8 convex lenses mounted around the lamp. The light beams then hits 8 arms each consisting of 1 x dichoric glass reflector and mirror.  This moves the beam of light in and out as an expanding and contracting motion.  The beams can hit the dichoric glass then shoot a colored beam of light or bypass and hit the mirror creating a white / clear beam of light or both.  In addition to the beams of light moving in and out there is a constantly rotating mirror drum on the bottom and an additional 8 sound active rotating glass mirrors that the beams of light can project off of.  Control of the unit is 0 - 10 volt analogue that brings up the internal programs and the 8 round mirrors constantly rotate to the beat of the music from an on-board mic with sound adjustment pot for sensitivity.  The original controller unfortunately has gone missing from the original owner - It was a small box that had an adjustment knob for the programs and a blackout button.  A few cool features of the unit are that the mirror drum comes off with 4 simple wing nuts, a hinged base for easy bulb replacement, a hinged door for access the the PCB electronics and each of the 8 arms are detachable.  4 set screws and a quick release for the power wires and they come off.  The unit is awesome to see in action!  Unit made in Taiwan.
