Usage Precautions

  • In order to maximize the light-absorption effect by the grooved shape on the surface, please make sure that the direction of the grooves are perpendicular to the light source.
  • There is light transmission due to micro foaming and grooved structure, which makes the material semi-transparent. Therefore it can not be used to block the transmission of light.
  • We cannot provide the raw material, this product always needs to be backed with double-sided tape.
  • For omni-directional light absorption, please check out our Fineshut SP variant.
