Beam Control

Drop-In Iris

City Theatrical Drop-In Iris is the simple way of changing the beam size of a fixed focus  ellipsoidal reflector spotlight.  Just drop in an Iris, adjust the handle to change the beam size from fully open to nearly fully closed.  We have Irises to fit a variety of popular lighting fixtures.
