Precision In-Camera Visual Effects & Soft Fill

The ARRI Flat Diffuser 4ft (L2.0052525) is a specialized magnetic light modifier designed for the 4-foot ARRI Omnibar 4 linear LED light. Providing a controlled 130° beam spread, this flat optical panel converts the fixture into a smooth, even light source with the classic characteristics of a traditional linear bar light. It is specifically engineered for setups where the Omnibar is placed directly in shot or used for live in-camera visual effects, ensuring clean, continuous illumination without harsh hotspotting.

Fast Magnetic Front-Loading Interface

Equipped with a magnetic mounting system, the 4-foot Flat Diffuser snaps directly onto the front face of the Omnibar 4. This allows gaffers, cinematographers, and crew members to rapidly swap between optics on set without using external frames, tools, or physical fasteners.

Slim Profile for Tight Rigging

Unlike rounded tube-style diffusers, the flush, flat design keeps the Omnibar's form factor extremely compact. This allows the fixture to fit easily inside vehicle interiors, tight set pieces, or low-profile ceiling mounts while preserving high color rendering and full-spectrum light quality.
