City Theatrical DMX Iris



The DMX iris is a simple way of motorizing your lighting fixture so it can change beamspreads as an effect in your show.  You could have a gobo that is revealed as you open the iris, or just change the size of a pool of light on stage.  Our DMX Iris is based on our proven and reliable AutoYoke Iris, and features incolloy leaves and brass fittings to withstand heat and corrosion.  It is driven by a stainless steel chain.  One DMX channel is used.
