The PyraLed® YT290 matte/gloss 1.8mm is one of the best light diffusers in our assortment. This thin diffuser offers a very high light transmission, while still creating a diffuse, evenly spread light result on a small distance between the light source and the diffuser.
The PyraLed® YT290 matte/gloss has a one-sided matte surface and a one-sided gloss surface. The diffuser is 1.8mm thick and has a light transmission of 90%. 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 diffusivity, a score that refers to how well the light is scattered, is 0.57. That gives the PyraLed® YT290 1.8mm has a distance factor of 1.8. This means that the distance between the diffuser and the leds needs to be 1.8 times larger than the distance between the led strips or led button cells themselves to get a nice and diffuse light result.
The PyraLed® YT290 diffuser is part of our collection with advanced diffusers. These diffusers are developed with the goal of reaching the highest possible quality. This can be seen on how they score on the variable ‘efficiency’. This is measured by multiplying the light transmission with the diffusivity. 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® YT290 is made from extruded acrylic. Light diffusers from extruded acrylic have good to excellent light technical properties and can be fabricated easily. The material is quite vandal proof, UV-stable and colourfast. It can be safely used outside, the colour doesn’t change when exposed to the sun. The fire classification of cast acrylic is E according to fire norm EN 13501. This is the European (EU) classification.
Extrusion is a continuous process, creating large batches per production run. This makes the material cheaper than cast acrylic, but it is also less flexible. Our assortment is less broad, because the minimum batch per production run is large. An additional benefit of this production method is the minimum thickness tolerance, compared to cast acrylic.
The PyraLed® YT290 with a one-sided matte surface and a one-sided gloss surface in 1.8mm thickness is in stock in sheet size 3000mm x 1200mm. If you need a smaller size for your application, we gladly offer material cut to size.
If you are looking for a diffuser that spreads the light diffuse while barely losing any of the emitted light, the PyraLed® YT290 matte/gloss 1.8mm is a great choice. With the minimum amount of thickness tolerance and excellent light technical properties of extruded acrylic, this diffuser can be applied in many situations. The PyraLed® YT290 can be used for light fixtures, displays, signing, profiles and window frames. Barfronts, signing and other esthetic applications are also possible. Because the material is UV stable and the colour is not influenced by the sun, you can safely use the sheet inside and outside.
Are you looking for a very efficient diffuser that can be placed closer to the light source. The PyraLed® YT275 might be the one you are looking for. This diffuser still offers a very high level of light transmission, but scores better on diffusivity than the YT290. This allows closer placement to the light source.
For constructive applications like floors, walls and full bars and desks, we recommend a thicker diffuser, like our PyraLed®3 10mm or the PyraLed® OPY3 satin/satin 10mm. These diffusers are made from cast acrylic.
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.
The PyraLed® YT290 is made from extruded acrylic. Diffusers from extruded acrylic 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.
