City Theatrical Drop-In Source Four Jr. Iris

Fixed focus ellipsoidals deliver a defined beam, but the beam size is set by the fixture. This iris gives lighting designers, electricians, and venue technicians a way to resize that beam on demand, so one profile spot can cover several looks in theater, corporate staging, touring, and installed venues. It is sized for the Source Four Jr. and fits into the fixture rather than adding another unit to the rig.

City Theatrical makes irises for a range of popular ellipsoidals, so a rig with mixed fixtures can standardize on one accessory style and one way of working. A handle-operated iris lets a focus crew or operator reset the beam quickly during tech, rehearsal, or changeover, and it can be adjusted across a continuous range rather than being limited to a few fixed sizes. Specifiers who need American-made accessories also get a domestic option from a dedicated theatrical lighting manufacturer.

Choose it when the goal is repeatable, hands-on beam control on a Source Four Jr. without changing fixtures, lenses, or focus. Match the part to your fixture model before ordering, since City Theatrical offers separate irises for the full-size Source Four and Strand SL units.
