LightPro 50mm Polyboard 2450mm x 1200mm - White polystyrene board (stand not included)

LightPro 50mm Polyboard (2450mm x 1200mm) - Studio-Grade Light Control and Contrast Management

The LightPro 50mm Polyboard is an ultra-lightweight, high-density polystyrene bounce board designed to deliver massive, optically neutral fill light and precise contrast control for professional studio lighting setups.

Built for the Demands of Modern Production

In high-end commercial and narrative production, controlling contrast ratios is just as critical as your key light. The LightPro 50mm Polyboard serves as a foundational grip essential for managing light spillage and elevating ambient fill. By wrapping a highly efficient, ultra-soft bounce into deep shadows, this 2450mm x 1200mm modifier helps cinematographers maximize the usable dynamic range of their camera sensors. When shooting uncompressed RAW or capturing at extreme bitrates for rigorous post-production color grading, illuminating the shadows cleanly with a polyboard prevents noise floor artifacts, ensuring pristine data capture in the darkest areas of your image.

Rigging large modifiers can often be cumbersome, but the construction of this board prioritizes speed and safety on set. Crafted from high-density expanded polystyrene (EPS), its minimal weight demands exceptionally low payload capacity from your grip hardware. This allows the board to be easily secured using standard duckbill clamps, polyboard spikes, or rolling bases without over-leveraging your C-stands. The rigid 50mm depth provides structural integrity, preventing the flex and bowing commonly seen in thinner, inferior foamcore alternatives during rapid repositioning or breezy soundstage conditions.

Furthermore, the board's surface is engineered for flawless color accuracy, guaranteeing zero Kelvin or tint shift when reflecting high-output LED or HMI fixtures. While continuous lighting setups require careful thermal management—especially when positioning modifiers near high-heat tungsten or dense COB arrays—the polyboard's passive, standalone nature allows for optimal airflow on set. Whether used as a pristine soft bounce or painted black on the reverse side for negative fill, it remains an indispensable tool for shaping cinematic light.

Production FAQ

How does the polyboard affect the color accuracy of my key light?

The optically neutral white surface guarantees a pristine reflection without introducing green or magenta tint shifts, maintaining the absolute color accuracy of your high-CRI/TLCI fixtures.

What is the best way to rig this 50mm board safely on set?

Due to its lightweight footprint, it places minimal demand on grip payload capacity and is best rigged using dedicated 50mm polyboard spikes attached to a C-stand grip head, or placed directly into a rolling floor base.

Is it safe to use this near high-output continuous lighting?

While the polyboard is excellent for reflecting modern LED fixtures, standard thermal management practices must be applied; maintain a safe operating distance when using extreme heat sources like high-wattage Tungsten or HMI lamps to prevent melting the polystyrene core.

Can it help maximize my camera's sensor performance?

Yes. By efficiently lifting the exposure of deep shadows without adding a secondary hard light source, the board compresses your contrast ratios, allowing you to fully utilize the maximum dynamic range of your sensor while keeping high-bitrate shadows completely noise-free.
