CU Phosco, working alongside Swedish partner Energisystem, has supplied a new LED high mast lighting solution for Södra’s timber yard in Mönsterås, Sweden. The project replaced ageing conventional lighting with high-performance LED floodlights, improving visibility and safety across the site while reducing installed power consumption by 24 percent.
Södra, one of Sweden’s largest forest industry groups, has upgraded the high mast lighting at its timber yard in Mönsterås with a new LED floodlighting solution from CU Phosco, delivered in partnership with Energisystem Sweden.
The project replaced an ageing conventional lighting installation that had reached the end of its operational lifespan. Light levels across the site had deteriorated over time, while sourcing replacement parts for the existing luminaires had become increasingly difficult and costly.
The new lighting scheme supports Södra’s ongoing focus on improving energy efficiency, reducing operational energy consumption and creating safer working environments across its facilities.
The project involved replacing 137 conventional luminaires mounted on existing lighting masts with a modern LED area floodlighting solution based utilising CU Phosco’s FL820 range.
Through careful lighting design, the total number of luminaires required was reduced from 137 to 106 while still achieving the required illumination levels across the timber yard.
The new installation uses FL20 LED floodlights with external drivers and is backed by a 10-year performance guarantee, helping to support long-term reliability and reduced maintenance requirements.
Installation works were carried out by Assemblin Oskarshamn, with Mikael Karlsson overseeing the installation.
The lighting upgrade has significantly improved both lighting quality and energy performance across the site.
Compared to the previous high-pressure sodium installation, the new LED lighting delivers a much whiter light with improved contrast and colour rendering, helping to improve visibility for staff, vehicle operators and site users. The enhanced visual conditions contribute to a safer working environment throughout the timber yard.
Post-installation lighting measurements carried out by Energisystem confirmed that the new lighting system is performing as expected and meeting the specified project requirements.
The upgrade also delivered a reduction in installed power consumption, supporting Södra’s wider sustainability and energy reduction objectives.
