Overview
The BDR-FS10 is a 4-leaf barndoor for KUPO FS-1000 / PS-1000 (1000 W / 1200 W), made for shaping the soft-edged output of Fresnel and prism convex class fixtures. It mounts into the fixture gel-frame slot and gives the operator four adjustable leaves for trimming spill without adding flags, clamps, or extra grip hardware.
Why It Matters
A Fresnel beam is intentionally soft, so the fixture itself does not provide a hard cutoff. Barndoors become the working edge of the light, especially for top light, back light, and sidelight positions where spill can land on scenery, masking, or camera frame.
Key Features
- 505 x 174 mm approximate outer dimensions match the host fixture size for a proper front-of-fixture fit.
- Four adjustable leaves let crew tune the beam edge while keeping the Fresnel focus and fixture position unchanged.
- Foldable blade construction makes the accessory easier to store with the matching fixture package.
- Matt black finish reduces reflections at the fixture face during high-output tungsten use.
Host Fixture
Designed for KUPO FS-1000 / PS-1000 (1000 W / 1200 W). Use BDR-FS10 for the larger FS-1000 / PS-1000 family and BDR-FS05 for the smaller FS-500 Fresnel.
Applications
A useful choice for theatre Fresnel rigs, studio top lights, back lights, rehearsal rooms, and small venue fixtures where beam control has to happen directly at the lamp face.
Compatibility
Use with the listed KUPO host fixture family and match the smaller BDR-FS05 or larger BDR-FS10 size to the Fresnel or prism convex model.
