The PyraLed®4 gloss/satin 4mm is a light diffuser from cast acrylic with an excellent price / quality ratio. The diffusers within this collection offer a good balance between high light transmission and good diffusivity. Because of the excellent price / quality ratio and the popularity of the PyraLed®4 4mm, we have developed a Greencast® option. Greencast® acrylic is made from 100% recycled pre- and post-consumer acrylic.
The PyraLed®4 gloss/satin 4mm has a one sided gloss and a one sided satin surface. The diffuser is 4mm thick and with a diffusivity of 0.78 it spreads the light well on a short distance from the light source. Diffusivity is a score that refers to how well the diffuser scatters the light. Because of the high diffusity, the distance factor is just 1.3. This means that the distance between the diffuser and the leds needs to be 1.3 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®4 4mm is 48%. 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.
The PyraLed®4 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 of increasing the light output.
The PyraLed®4 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.
The PyraLed®4 with a one-sided gloss surface and a one-sided satin surface in 4mm thickness in stock in sheet size 3050mm x 2030mm. If you need a smaller size for your application, we gladly offer material cut to size.
The PyraLed®4 gloss/satin is also available in 3mm thickness in the same sheetsize. We also offer a Greencast® option in 3mm. Greencast® is made from 100% recycled pre- and post-consumer acrylic and offers the same material and lighting characteristics as the regular cast acrylic version.
If you are looking for a diffuser that offers high diffusivity and can be placed close to the light source, the PyraLed®4 is a great choice. And since cast acrylic has the best light technical properties of all light diffusers, you can apply the PyraLed®4 in many situations. You can apply the 4mm thick version of the PyraLed®4 with a one-sided gloss surface and a one-sided satin surface for barfronts, signage, decors, displays and other esthetic applications. You can use both the gloss and the satin side. Because cast acrylic is UV stable and the colour is not affected by sunlight, you can safely apply it inside and outside.
For constructive applications like floors, walls and full bars and desks, you need a thicker diffuser, like the PyraLed®3 10mm satin/satin.
Are you looking for a diffuser that transfers more light? Then the PyraLed® OPY2 satin/satin 3mm might be the right choice for you. This diffuser is developed with the goal of achieving the highest possible light transmission. You will keep more of the emitted light of the light source after applying the diffuser.
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.
Diffusers made from cast acrylic contain less tension than diffusers from extruded acrylic. The PyraLed®4 is made from cast acrylic and can be fabricated easily.
PyraSied has more than 30 years of experience in fabricating acrylic and other plastics. With our excellently equipped workshop – where high-tech machinery and traditional craftsmanship ensure high quality – we can supply diffusers made to size. Whether you are looking for a partner for a one-time project or a trustworthy partner for the continious supply of diffusers as part of your supply chain, PyraSied is the right choice.
You can fabricate acrylic yourself, often with the same tools used for wood fabricating. Fabrication options for the PyraLed®4 diffuser are lasering, sawing, milling, bonding, drilling, faceting, polishing, sanding and printing.
