Product Description
Overview
The ETP-BDR is a 4-leaf barndoor for ETC Source Four Par and ParNel fixtures, built to trim spill from broad, diffuse beam sources. Its foldable adjustable leaves mount at the fixture face, giving the operator a practical way to shape coverage without moving the whole fixture or adding external flags.
Why It Matters
Source Four Par and ParNel fixtures are valued for usable washes, but broad beams can wander onto scenery, audience areas, or camera frames. A correctly matched barndoor gives the crew a cleaner edge while keeping the fast, familiar PAR-style setup.
Key Features
- 4-leaf design gives independent top, bottom, and side spill control at the fixture face.
- 191 x 191 mm dimensions match the Source Four Par / ParNel accessory format.
- Foldable adjustable leaves pack cleanly and can be shaped for different beam-control needs.
- Matt black finish reduces reflections around the front of the fixture.
Host Fixture
Designed for ETC Source Four Par and ParNel fixtures. Use this standard barndoor when the job needs adjustable spill control; choose the related ETP-BDR2 when a color extender version is required.
Applications
A useful accessory for theatre washes, studio side light, event PAR systems, worship lighting, and rental fixtures where broad beam coverage needs cleaner boundaries.
Compatibility
Fits ETC Source Four Par and ParNel fixtures; check accessory frame size before using with non-ETC or modified fixture bodies.
Frequently Asked Questions
Why does a Source Four Par need barndoors?
Its broad beam is useful, but it can spill beyond the intended area. Barndoors let crew trim that spill without changing fixture aim.
Is this the version with a color extender?
No. This is the standard ETP-BDR barndoor. Use ETP-BDR2 when the color extender version is needed.
Can I use it on a regular Source Four ellipsoidal?
No. It is for Source Four Par and ParNel fixtures, not the standard ellipsoidal profile body.
