It is a tool INTERESTED trs, to play on the color of the Atomic. It is Designed to move some centimtres regulirement (one way then the other) so that the filters do not heat up too much under the influence of strob.
It has its own power, but takes the DMX on the Atomic.
It is a product that can stepfather expensive, but it can give another dimension to the strobe effects. It's really original.
