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.

They do not shatter in the event of impact, flashover or vandalism.” – so no need for a sealing gasket or protective cover.
They are designed and made in Italy.
