1/4 Tough Spun Diffusion Sheet

The Lee Filters 1/4 Tough Spun sheet measures 24 by 21 inches and softens harsh light for photography and video work. It reduces contrast and glare while spreading illumination evenly across the scene. The material is built to withstand repeated handling in studio or location environments.

Heat and power in use

The filter sheet is a passive light modifier, so it generates no heat, draws no power and produces no noise during operation. It simply sits in front of a light source and alters the quality of the beam. Thermal management and electrical load remain entirely dependent on the fixture you are using.

Mounting and workflow impact

The sheet ships as a flat piece of diffusion material without frames, clips or adhesive backing. You must supply your own method of attachment such as a frame, tape or clamps to fit the 24 by 21 inch dimensions. No software, drivers or calibration tools are included or required for use.

Questions about this item

How do I install the 24x21" Tough Spun sheet on a frame or light, and what step is often missed?

Cut or trim the sheet to fit your frame, then secure the edges with clips or tape; the step often missed is stretching it evenly so no wrinkles create uneven diffusion.

What maintenance or replacement will the 1/4 Tough Spun sheet need over time?

Wipe gently with a dry microfiber cloth when dusty; replace the sheet if the spun fibres become permanently creased, yellowed or torn, as these defects alter light quality.

What limit appears first when the sheet is used continuously under hot studio lights?

The polyester base softens and can sag if placed too close to high-output tungsten or HMI heads; keep a safe distance or switch to cooler LED fixtures to avoid deformation.
