Roscolux Light Hamburg Frost 20x24" Diffusion Sheet

SKU CH-AFKB-R1Y1C

A 20x24 inch diffusion sheet that softens studio, strobe or LED light for even, shadow-free illumination

  • Soft, even diffusion reduces harsh shadows
  • 20x24 inch sheet balances coverage and portability
  • Versatile for studio lights, strobes or LED panels
  • Durable construction withstands repeated professional use
  • Tri-extrusion process encapsulates colourant for lasting vibrancy

Professional diffusion sheet

The Roscolux Light Hamburg Frost is a 20x24" sheet of premium light-diffusing material designed for photographers, videographers and lighting technicians who need to soften harsh beams from studio lights, strobes or LED panels. It delivers smooth, even illumination that reduces hard shadows and creates a naturalistic look for portraits, product shots and cinematic scenes.

Tri-extrusion construction

An innovative three-layer process encapsulates the colourant between two ultra-thin clear films, which significantly reduces dye migration and preserves the filter's vibrancy over time. This advanced build ensures consistent performance and exceptional durability even under intense stage or studio heat, extending the usable life of the sheet in demanding professional environments.

Polycarbonate-based material

Over 65% of the Roscolux range uses robust co-extruded polycarbonate plastic, while the remainder is deep-dyed polyester, so heat resistance and handling characteristics follow that specific blend. Buyers who need a different substrate, a larger roll format or a heavier diffusion density should look elsewhere, as this single sheet is optimised for its stated 20x24" dimensions and the Hamburg Frost formulation.

Questions about this item

How often will the Roscolux Hamburg Frost sheet need replacing under hot stage lights?

The tri-extrusion construction encapsulates the colourant between clear film layers, reducing dye migration and prolonging vibrancy so the sheet lasts through extended productions.

What is the first limit reached when the sheet is used continuously on high-output fixtures?

The 20x24 inch surface defines the maximum beam coverage; once the light spread exceeds that area, additional sheets or a larger filter are required.

Does the polycarbonate material generate extra heat or noise when run all day?

The passive diffusion sheet adds no fan noise or power draw; it simply transmits and softens the beam while withstanding sustained high temperatures.
