Retrofit of streetlighting in a residential area (Gdansk-Pomerania)

Share this Post:

The project SOWA Nieborowska consisted of the refurbishment of the public lighting along the street Nieborowska in Gdansk (Illuminated area: 20,437 m²). The project was triggered by the willingness to improve safety and security by upgrading the street lighting. Initially it was planned to exchange the lighting to sodium lamps with lower capacity. However, this solution was replaced with LED lamps due to innovation and higher energy savings of LED technology. The lighting was modernized, 16 lighting points with a previous capacity of 75 W or 115 W per luminaire, were refurbuished to energy efficient LED technology. Safety has also been improved.


This case study was developed in the context of the EU-Project Streetlight-EPC which is supported by the Intelligent Energy Europe Programme.
