Matthews' Stainless Steel Wire Diffusion (SST) resists rust and endures uneven, intense heat, making it ideal for open face or Fresnel lighting fixtures. Unlike diffusers, these scrims reduce light output at the source without altering color temperature or causing electronic interference. They can be stacked for infinite light intensity variation and are available in sizes from 5" to 29" to suit most professional lights. Scrims come in single, double, half single, and half double configurations, with halves used to balance light when striking a plane at an angle.
