Overview
The KUPO ETI-F18 is an 18-leaf manual iris for S4 / Shakespeare / S6 Series. It gives profile-style luminaires a clean mechanical aperture control, useful when the beam needs to be tightened without changing the lens setup or refocusing the whole fixture.
Why It Matters
A profile fixture often needs small beam-size changes during focus, rehearsal, or rental prep. ETI-F18 gives technicians a familiar 18-leaf iris format with heat-resistant leaves and fixed focusing holes, so the accessory can be positioned quickly and adjusted smoothly.
Key Features
- 18-leaf iris design supports controlled circular aperture changes in compatible profile fixtures
- 4.5 mm to 75 mm aperture range covers tight specials through wider open looks
- Stainless steel leaves with 450 °C heat-resistant coating suit theatrical fixture environments
- Three fixed focusing holes help the accessory seat consistently in the fixture slot
- Dimensions match the S4 / Shakespeare / S6 format listed in the specification
Applications
Use it for performer specials, theatre focus sessions, studio fixtures, venue profile lights, and productions that need repeatable beam-size control from S4, Shakespeare, or S6 Series fixtures.
Compatibility
Compatible with S4 / Shakespeare / S6 Series, with listed dimensions A 120 mm, B 137 mm, C 13 mm, and D 102 mm.
