Silicone Lenses for COB LEDs

Khatod has introduced silicone lenses for CoB arrays, called SIO3. The material has been chosen for its: sustained transparency over years, resistance to yellowing, UV-resistance, optical efficiency, lack of birefringence, temperature resistance (-40 to 150°C, 200°C peak), and flexible at low temperatures. Designed for streetlights, depending on the LED used, they can comply with IESNA Standards: Type I, Type II, Type III, Type IV, Type V, short or medium light distribution. These are large beasts: 111x110mm and around 35mm high.
