Medium Diffusion

Our Medium Diffusion LED Diffuser Sheets are the workhorse of the modern lighting industry. While clear sheets offer no protection against harsh LED “glare” and strong diffusers can reduce light output, our medium-grade sheets find the perfect equilibrium. By utilizing high-quality light-scattering agents embedded within the polymer matrix, these sheets transform discrete LED points into a soft, continuous glow while maintaining a high lumen-per-watt ratio.

Key Features

  • Optimal Balance: Provides a significant reduction in pixelation and “zebra stripping” while maintaining high light transmission.
  • Satin-Matte Finish: Features a sophisticated surface texture that minimizes external reflections and resists fingerprints and scratches.
  • Color Neutrality: Engineered to ensure that the Correlated Color Temperature (CCT) of your LEDs remains consistent without shifting toward yellow or blue.
  • Excellent Thermal Stability: Designed to withstand the heat generated by high-density LED strips without warping or discoloring over time.
