Rambo luminaires of Czech manufacturer Vyrtych are protected against vandalism through robust lamp covers made from Makrolon® polycarbonate from Covestro.

Vandalism-resistant luminaires from Czech manufacturer Vyrtych are used in areas where willful or negligent violent impacts are commonplace. They provide for effective and long-lasting illumination in such places as public buildings and parking garages. The materials used to make the robust luminaires therefore must satisfy some special requirements.

Covestro markets various grades of its Makrolon® polycarbonate for special applications in lighting engineering. Vyrtych also turns to the high-performance plastic to manufacture its Rambo series of vandalism-resistant luminaires. “Lamps are particularly susceptible to violent impacts,” said Dominik Popovský, product manager at Vyrtych. “Polycarbonate, on the other hand, provides for long-lasting brightness because it is every bit as robust as it is transparent.”

The durability of the Rambo luminaires is due to the high impact strength of the polycarbonate lamp cover made of Makrolon® ET3227. This Covestro material is very easy to process using extrusion. One noteworthy attribute of this material is its good dimensional stability, which enables components to be manufactured with high precision and reproducibility. When the temperature resistance and good fire performance are also considered, Makrolon® ET3227 offers clear advantages over similar products made from other thermoplastics or glass.
