9: Case Study: Thailand Rural Roads Achieve 144% Brighter Lighting & 62% Energy Savings with Reapway LED Streetlights
1) Introduction
To enhance road safety and energy efficiency, a 10 km rural road in Bangkok, Thailand, underwent a transformative
lighting upgrade. The project focused on replacing outdated 400W Metal Halide streetlights with Reapway 150W
150LM/W LED Streetlights (RTL-LD-F150W). This initiative aimed to solve poor illumination, high energy costs,
and frequent maintenance challenges while complying with local safety and lighting standards.
2) Setting the Scene
The rural road, critical for local commuters and transport, previously relied on:
- 400W Metal Halide Lamps:Aging fixtures produced an average illumination of 90 lux, with uneven coverage and frequent outages.
2.High Operational Costs:Energy-intensive lamps consumed excessive power, straining municipal budgets.
3.Safety Concerns:Dark spots and inconsistent lighting increased accident risks, especially during nighttime.
Local authorities sought a solution that delivered uniform illumination, reduced energy consumption by at least 50%,
and adhered to Thailand’s roadway lighting standards.
3) Results Overview
By deploying 201 Reapway 150W LED Streetlights at 40-meter spacing, the project achieved remarkable outcomes:
- Illumination Surge:Average light levels rose from 90 lux to 220 lux, ensuring uniform coverage and eliminating dark zones.
2. Energy Savings:Power consumption dropped by 5%, saving 28,980 kWh annually (see table below).
3.Cost Efficiency:Total annual energy costs fell from $5,227.20 to $1,968.30, saving $3,258.90.
4) How It Was Done
Reapway’s end-to-end service ensured seamless execution:
- Lighting Design & Compliance:Layouts were optimized for 40-meter spacing, meeting EN 12464-1 illumination standards.
2.Cost Optimization:Bulk procurement reduced initial costs by 20%, while durable fixtures minimized long-term maintenance.
3.Quality Assurance:Post-installation lux-level audits confirmed compliance and uniformity.
5) Customer Reviews
Mr. Somchai Srisuk, Bangkok Municipal Engineer:
“Reapway’s LED streetlights have revolutionized our rural roads. The 220 lux illumination ensures safer commutes,
and the 62% energy savings exceeded our expectations. Their team’s professionalism made the transition effortless.”
6) Conclusion
The Bangkok Rural Road upgrade demonstrates how Reapway’s high-efficiency LED streetlights can transform infrastructure
in emerging markets. By slashing energy costs, boosting safety, and ensuring regulatory compliance, this project paves the
way for scalable, sustainable lighting solutions across Thailand’s rural networks.
