    The PyraLed®3 satin/satin 20mm is a light diffuser from cast acrylic with an excellent price / quality ratio. The diffusers within this collection offer a high diffusivity and are available in high thicknesses.  That makes them well suited for constructive applications and applications where the diffuser is placed close to the light source.

    The PyraLed®3 20mm has a two-sided satin surface, is 20mm thick and with a diffusivity of 0.62 it spreads the light well on a short distance from the light source. The diffusivity is a score that refers to how well the diffuser scatters the light. Because of the high diffusivity, the distance factor is 1.6. This means that the distance between the diffuser and the leds needs to be 1.6 times larger than the distance between the led strips or led button cells themselves to get a nice and diffuse light result. The light transmission of the PyraLed®3 20mm is 16%. The light transmission refers to the amount of light that comes through the diffuser. It is measured on the other side of the light diffuser than where the light source is positioned.

    Professional diffuser

    The PyraLed®3 diffuser is part of our collection with professional diffusers. With the help of extremely precise process control and the use of nano additives, the professional diffusers are more efficient than standard diffusers. They offer a higher light transmission with the same diffusivity or a higher level of diffusivity with the same light transmission. The light transmission is a measurement of the amount of light transmitted. The diffusivity refers to to how well a diffuser scatters the light. A diffuser that has a higher score on the variable ‘efficiency’ performs better. An efficient diffuser is more expensive to purchase, but earns itself back by saving energy or increasing the light output.

    Material characteristics

    The PyraLed®3 is made from cast acrylic. Light diffusers from cast acrylic have the best light technical properties and are optically clear, UV-stable and colourfast. Because of this, the diffusers can be used inside and outside and the colour will not be influenced by the sun. The fire classification of cast acrylic is E according to fire norm EN 13501. This is the European (EU) classification.

    Cast acrylic can be produced in smaller batches relatively easy. This allows us to offer the broadest collection of thicknesses and types in cast acrylic.

    Applications for the PyraLed®3 satin/satin 20mm

    If you are looking for a diffuser that offers high diffusivity and can be placed close to the light source, the PyraLed®3 is a great choice. And since cast acrylic has the best light technical properties of all light diffusers, you can apply the PyraLed®3 in many situations. You can apply the 20mm thick version of the PyraLed®3 with two-sided satinated surface for barfronts, signage, decors, displays and other esthetic applications. Because the thickness of the sheet, you can use the diffuser for constructive applications like floors, walls and full desks and bars. Because cast acrylic is UV stable and the colour is not affected by sunlight, you can safely apply it inside and outside.

    Are you looking for a diffuser that offers a higher level of light transmission? Then the PyraLed® OPY2 satin/satin 10mm might be a better choice. This diffuser has a high level of light transmission. You will keep more of the emitted light after applying a diffuser with a high light transmission.

    Cast acrylic has thickness tolerance, making it less suitable for the use in light fixtures and profiles. Extruded acrylic (XT) has minimum thickness tolerance, making it a perfect match for these applications. The PyraLed® YT275 matte/gloss is an excellent alternative in XT, offering a light transmission of 81%.

    Looking for inspiration? Please check our Acrylic community. You can find many applications with light diffusers. There are also many other applications with acrylic on the platform.

    Fabricating the PyraLed®3 satin/satin 20mm
