A moving-mirror built by Rosco designed to slide into the gel frame holder of a modern ERS fixture. DMX-controlled, the mirror moves the beam of light while leaving the light stationary. A much cheaper and easier alternative to a moving light. I-Cues require the use of a 24-volt DC "color scroller"-type Power Supply. DMX cable (5pin XLR) and non-dimmed AC run to the Power Supply and, a 4pin XLR cable ("scroller cable") carrying DMX plus power runs to the I-Cue.
