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 Brightness levels were no longer sufficient, and the technology was outdated and inefficient.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.
