High technical parameters and wide possibilities of application of ST-52 luminaires are the result of combining POLLIGHT's experience in the field of road lighting and the needs and requirements of the Polish lighting market.

ST-52 luminaires, due to the modern design and use of proven components, are placed at the top of the high-quality products characterized by:

• High durability
• Lifetime estimated to be 20 to 30 years
• High light efficiency
• Variety of photometric parameters

The ST-52 POLLIGHT series luminaires are ENEC PLUS certified by SEP – BBJ and ZHAGA D4i certified by DEKRA.

The production of ST-52 series frames takes place in Poland, in a factory with implemented ISO quality standards required by the research unit SEP – BBJ under the ENEC certificate.

ST-52 luminaires perfectly illuminate national, urban, county and municipal roads and pedestrian crossings, pavements, squares, parking spaces and workplaces, while complying with PN-EN 13201:2016 and PN-EN 12464-2 standards.
