City Theatrical Drop-In Iris

Write a Review

A 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.

CTI provides a limited lifetime warranty on all of its manual drop in irises. 


  • Offers precise, smooth control of beam size
  • Specially made leaves are tempered and heat resistant to over 1000°F (538ºC)
  • Fits easily into most standard theatrical ellipsoidals
