Macro photograph of the light diffusing material surface. Made by German Evonik, both surfaces consist of stochastic refracting structures. Durable for dirt and attrition.





  • Hermetically seals the 12x LED assembly, protecting from dirt, moisture, etc., resulting in a dramatic increase of LEDs’ lifespan and maintaining constant light output * 
  • Effectively mixes the radiation of all LEDs on the 12x LED assembly, minimizing the "disco effect" 
  • Can be used on LEDs with or without secondary optics 
  • Easy to attach to the MCPCB using a silicone sealant, preferably neutral type. Do not use Cyanoacrylates, also known as "superglue"
