Bought these two jems from a Sound and Light Maintenance company in the UK. When I received them, I saw the real state they were in, and after washing, polishing, and re-wiring, they were as new. Not a spectacular disco effect. It is a slow turning Clay Paky Double Tarantula head with a 24V 150W lamp inside. It turns about 2 rpm and the effect is like a mirrorball. Very rare, I might add!!!
