Thanks to the reinforcement made of polycarbonates and ceramics, lamps are characterized by extremely high strength, shock viscosity, which is why they are popular. At the same time, for the sake of improving the mechanical properties, polycarbonates are filled with fiberglass. Polycarbonate-glass-and-white compositions have a long service life, are not exposed to adverse natural phenomena, such as rain, snow, wind, ice, sunlight.
