6: Case Study: REAPWAY LED Floodlights Cut Energy Costs 72%, CO₂ Emissions 69% at German Mall
1) Introduction
Main-Taunus-Zentrum (MTZ), a leading shopping center in Sulzbach, Germany, prioritized sustainability by upgrading
its outdoor parking lot lighting. The project replaced outdated 400W Metal Halide Lamps with REAPWAY 150W LED
Floodlights (RT-S8-150W), renowned for 150LM/W efficiency and durability. This initiative enhanced illumination quality
while aligning with MTZ’s energy-saving and environmental goals.
2) Challenges with Existing Lighting
The existing system posed critical issues:
- High Energy Costs: 400W lamps drove soaring electricity bills.
- Poor Illumination: Aging fixtures (~80 LM/W) caused dim, uneven lighting.
- Frequent Maintenance: Short lifespan (10k–15k hours) led to disruptions.
- Environmental Impact: Excessive energy use contradicted sustainability targets.
3) The Solution
12pcs traditional 400W lamps were replaced with 10pcs REAPWAY RT-S8-150W LED Floodlights, offering:
Superior Energy Efficiency:
150 lm/W efficacy (vs. 80 lm/W for metal halide)
62.5% power reduction (400W → 150W per fixture)
Maintained equivalent brightness while eliminating wasted light
Long-Term Reliability:
50,000-hour lifespan (3-5x longer than metal halide)
4) Results Overview
The upgrade delivered transformative outcomes:
*Includes energy (0.18/kWh) and maintenance costs (0.18/kWh) and maintenance costs (100 vs. $20 per fixture).
Key Benefits:
- $3,601/year saved in energy and maintenance.
- Enhanced safety with uniform, bright illumination.
- Eco-Friendly: Cut CO₂emissions by 69%, supporting MTZ’s sustainability targets.
- Longevity: 50,000-hour lifespan minimizes replacements and downtime.
5) How It Was Done
The project was carried out in four efficient steps:
- Site Audit: Identified high-traffic zones needing priority upgrades.
- Fixture Selection: Chose RT-S8-150W for durability, efficiency, and beam flexibility.
- Seamless Retrofit: Modular design enabled quick installation without structural changes.
- Quality Assurance: Rigorous testing confirmed compliance with EN 12464-1 standards, achieving uniform lux levels and eliminating dark spots.
6) Customer Feedback
Hans Müller, MTZ Project Manager:
“The LED floodlights transformed our parking areas. Energy bills dropped instantly, and the crisp light improved safety.
Maintenance costs are now negligible—this upgrade was a game-changer!”
7) Conclusion
MTZ’s lighting overhaul demonstrates how advanced REAPWAY LED lights drive sustainability and efficiency in
commercial spaces. By cutting energy use by 69% and slashing costs, MTZ sets a benchmark for eco-conscious
retail operations.
