StuCo-Owned Lighting Equipment
Cahn/ Shanley Stock
Student shows also have the option of renting from a stock of older, used instruments from Cahn Auditorium. Though these instruments are in poorer shape than those provided by the professional companies above, they are significantly cheaper and more convenient.
The Wirtz Center for the Performing Arts owns a gel stock, gobo stock, and a variety of different gel strings for use in Wybron 7" Forerunner scroller units that they will occasionally rent to StuCo shows. Information on the gel strings can be found here: 
Most student shows tend to rent equipment from ILC because it is closest, but there are three main lighting rental companies in Chicago that shows have rented equipment from in the past.
