LED tube retrofit at Shoppi Tivoli shopping centre, Spreitenbach

The Challenge

The previous lighting in the parking and pedestrian areas was energy-intensive, maintenance-heavy, and no longer up to modern standards. The objective was to find an energy-efficient LED lighting solution that would reduce operating and maintenance costs while improving safety and comfort for visitors.

The Solution – LED Retrofit with GLT LED TUBE

A total of 5,400 T5 and T8 fluorescent tubes were converted to GLT LED TUBES in a 1:1 retrofit process in accordance with IEC/EN 62776 by the in-house technical team — all carried out during ongoing operations in the parking areas of the shopping center.

The existing luminaires and fixtures were retained but professionally rewired, while the old drivers were removed. The driver of the GLT LED TUBE is fully integrated into the tube itself, allowing future replacements to be easily carried out by staff without electrical training.

As a result, maintenance costs are reduced to an absolute minimum — supported by the exceptionally long service life of up to 130,000 hours. The new LED lighting meets all legal requirements for safety, 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 our LED retrofit solution for Shoppi Tivoli:

• Significantly lower energy costs: Shoppi Tivoli saves around 1.7 million kWh of electricity annually, with a payback period of just one year.
• Virtually maintenance-free: the durable retrofit technology has reduced maintenance effort to an absolute minimum.
• Optimal illumination of parking areas and pedestrian zones with individually adapted light colors for enhanced safety and comfort.
• Sustainable solution: Environmental Product Declaration (EPD) according to ISO 14025, GLT multi-use system, high recycling rate, long service life, and the preservation of the existing luminaire infrastructure ensure both ecological and economic advantages.
