LogiTech GmbH, a mid-sized logistics provider based in Hamburg, Germany, operated their 5,000 sqm distribution center with 400W metal halide high bays installed in 2012. By 2024, the fixtures had degraded significantly, with average illuminance dropping below 200 lux — well below the recommended 300 lux for warehouse operations.
Challenge
- Annual lighting electricity cost: €62,000
- Lamp replacements required every 12-18 months at €8,000 per cycle
- Worker safety complaints due to dark spots in racking aisles
- Corporate sustainability targets required 40% energy reduction
Solution
We replaced 120 units of 400W metal halide with our 200W LED high bay lights equipped with occupancy sensors. A DIALux simulation ensured uniform 350+ lux across all aisles and loading areas.
Results
- Energy consumption reduced from 48kW to 18.2kW (62% savings)
- Annual electricity cost dropped to €24,000 — saving €38,000/year
- Maintenance costs eliminated for 5 years under warranty
- Average illuminance increased to 380 lux with 0.85 uniformity
- Total ROI achieved in 18 months
