LED lighting for Nordstan Parking in Gothenburg

The Challenge

The previous fluorescent lighting in Nordstan’s parking garages and underground facilities led to high energy consumption and frequent maintenance requirements. Brightness levels were no longer sufficient, and the technology was outdated and inefficient. A standardized LED solution was required – one that would reduce costs while providing reliable, long-term operation with optimal illumination.

The Solution – LED Retrofit with the GLT LED TUBE

A total of 3,849 T5 and T8 fluorescent tubes were converted to GLT LED TUBES in a 1:1 retrofit process in accordance with IEC/EN 62776 in the parking garages and underground car parks of Nordstan. The existing luminaires and fixtures were retained and upgraded, while the old ballasts were bypassed. The ballast of the GLT LED TUBE is integrated directly into the tube — allowing future replacements to be carried out easily by staff without electrical expertise.

Maintenance costs have been reduced to an absolute minimum, supported by the exceptional service life of up to 130,000 hours of the GLT LED TUBE. The new LED lighting meets all legal requirements for CE conformity, energy efficiency, and sustainability. Thanks to the Environmental Product Declaration (EPD) of the GLT TUBE, all environmental impacts of the lighting can be transparently measured and documented.

Key advantages of the LED retrofit for the Nordstan parking facilities in Gothenburg:

• Annual energy savings of 1,302,197 kWh with a payback period of only 7 months.
• Integrated high-performance driver and certified compliance with DIN EN 62776 ensure maximum operational safety and reliability.
• Virtually maintenance-free and long-lasting LED lighting, ideal for 24/7 use in parking garages and underground facilities.
• Sustainable, future-proof solution for permanently reducing energy and maintenance costs while ensuring optimal illumination of driving lanes and parking areas. EPD Environmental Product Declaration in accordance with ISO 14025.
