6 years
This is the return on investment for a remote management project deployed on 2,000 LED streetlights*. Using IoT sensors installed on existing equipment (with no preloaded dimming profile), a dynamic dimming strategy was implemented:
Standard Profile:
- 100% until 10:00 PM
50% from 10:00 PM to midnight
20% from midnight to 4:00 AM
50% from 4:00 AM to 6:00 AM
100% from 6:00 AM onwards
Result: Efficient energy consumption reduction without compromising lighting comfort.
- Investment paid back in 6 years, followed by net savings during the remaining 4 years of the contract (10 years total).
- Positive cash flow starting from year 6.
Looking further: A project involving the full replacement of sodium lamps with LED luminaires and sensors offers an even shorter ROI—only 4 years.
*Average luminaire power: 60W
Energy Consumption
Annual consumption without dimming → €85,680 in electricity
Annual consumption with dimming → €58,078 in electricity
Annual consumption with dimming → €58,078 in electricity
Maintenance
Advantages of connected management:
• Immediate failure detection (no more manual inspection rounds)
• Optimized interventions (grouped, better scheduled)
• Anticipation of failures through alerts
With an annual maintenance cost of approximately €20 per light point, for 2,000 points: up to 30% savings on maintenance costs, i.e. €12,000 saved per year.
