Abstract

In today’s era of sustainable development, solar landscape lighting has become the preferred solution for public space illumination. This paper provides an in-depth analysis of a successful case study in which a renowned coastal park in the United States upgraded its lighting system using the SRESKY Honor Series solar landscape lights. The project addressed challenges posed by traditional lighting systems, including high operational costs, environmental impact, and incompatibility with the park’s natural aesthetics. As a leader in smart streetlight technology, the application of the SRESKY Honor Series in this coastal park offers valuable insights for similar projects worldwide, advancing the adoption of sustainable lighting solutions.

I. Project Background and Needs Analysis

1.1 Project Background: Preserving a Serene Coastline

Located on the East Coast of the United States, this renowned coastal park spans vast grounds, blending natural landscapes with recreational amenities. Featuring manicured lawns, lush tropical vegetation, golden sands, and shimmering ocean vistas, it attracts millions of visitors annually for relaxation, leisure, and community events. The coastline is not only a biodiversity treasure—home to diverse bird species and marine life—but also an urban oasis offering respite from city life.

However, with accelerating urbanization, the park’s nighttime lighting needs became increasingly critical. The existing grid-powered system relied on aging equipment and faced multiple problems: salt spray corrosion caused frequent fixture failures, electricity costs reached tens of thousands of dollars annually, and light pollution disrupted coastal ecosystems, such as sea turtle nesting. Park management recognized the urgent need for a sustainable lighting solution to preserve this tranquil environment while enhancing its role as a community hub.

1.2 Core Requirements Analysis: Challenges Across Four Dimensions

The new lighting solution was required to address four key dimensions:

• Sustainability and Environmental Protection: Powered by 100% clean energy to reduce the carbon footprint. Light pollution had to be minimized to protect nocturnal wildlife and marine life, aligning with the United Nations Sustainable Development Goals (SDGs).

• Safety and Security: With frequent nighttime activities, reliable lighting was essential for pathways, rest areas, and beach access. The system needed to provide uniform, responsive illumination to reduce accident risks, especially for seniors and children.

• Aesthetics and Integration: Inspired by 18th-century retro design, the fixtures needed to appear “classic and elegant.” Concealed solar panels and European-inspired styling ensured seamless integration with the natural landscape.

• Durability and Economy: The coastal environment required high resistance to salt spray, humidity, and storms. Reduced maintenance and long-term cost efficiency were priorities to ensure a rapid return on investment.

II. Technical Solution Design

2.1 Product Selection: SRESKY Honor Series

After multiple evaluations, the park selected the SRESKY Honor Series solar landscape lights. Specifically designed for public outdoor spaces, the series integrates high-efficiency monocrystalline silicon solar panels (>23% conversion), lithium-ion batteries, and OSRAM LEDs. Delivering 3000 lumens brightness, IP65 protection, and IK08 impact resistance, the Honor Series provides reliable performance in demanding coastal environments.

2.2 Technical Adaptability Analysis: Tailored for Coastal Conditions

The SRESKY Honor Series incorporates innovative technologies that make it particularly well-suited for seaside applications.

• Design Aesthetics: Retro European styling, elegant curves, and concealed solar panels avoid the bulky look of traditional solar lights. The design integrates seamlessly into the park’s classical landscape, adding visual appeal while maintaining harmony with nature.

• Environmental Durability:

  • IP65 Rating: Dustproof and water-resistant, capable of withstanding coastal humidity and rainfall. Salt-fog tests show corrosion resistance exceeding industry averages.

  • Wide Temperature Range: Operates from -20°C to +60°C, ensuring stable year-round performance in both extreme winters and hot summers.

• Core Technology Assurance:

  • ALS 2.4 (Adaptive Lighting System): Adjusts power output to ensure over 10 days of illumination during continuous rainy conditions. By monitoring ambient light and battery levels, it optimizes energy consumption and prevents outages.

  • TCS 1.0 (Temperature Control System): Monitors battery temperature in real time to prevent overheating or freezing, extending battery life to thousands of cycles. Combined with vibration-assisted dust reduction, efficiency is further enhanced.

• Smart & Efficient Lighting:

  • Dual PIR Sensors: Two wide-angle (120°) sensors with >3m detection range enable dynamic lighting: 30% brightness + PIR trigger when people approach, and 15% constant brightness when they leave. This reduces energy consumption by 80% while minimizing disturbance to nocturnal wildlife.

  • Multiple Lighting Modes:

    • M1: 30% PIR + 15% constant until dawn (for trails).

    • M2: 30% constant until dawn (for high-traffic areas).
      Staff can easily switch modes via button to adapt to different park zones.

  • High Luminous Efficacy: At 3000 lumens, fixtures illuminate 14-meter intervals with 5000K natural white light (Ra>90). Optimized light distribution minimizes glare while ensuring comfort and safety.

These features make the Honor Series both technologically advanced and environmentally adaptable, perfectly suited for the park’s needs.

III. Project Implementation and Deployment

3.1 Strategic Layout

Based on visitor flow analysis, luminaires were positioned along pathways, rest areas, and high-traffic zones. Recommended installation height was 3 meters with a 14-meter illumination span, ensuring uniform coverage without dark spots. GIS simulations optimized light distribution while minimizing the total number of fixtures, reducing costs.

3.2 Commissioning and Activation

The lights were activated by pressing the control button for 1.5 seconds to select the desired mode (e.g., M2 for balanced ambiance and efficiency). Red/green indicators provided clear battery status feedback, simplifying activation and maintenance.

IV. Project Outcomes and Impact

4.1 Social Value: Safer, More Attractive Public Spaces

Post-implementation, visitor safety perception improved by over 30%. Extended nighttime lighting enabled longer park hours and enriched community activities. Feedback highlighted the park’s enhanced reputation as a sustainable and welcoming destination.

4.2 Environmental and Economic Sustainability

• Zero Operating Costs: 100% solar-powered, saving tens of thousands in annual electricity costs.

• Reduced Carbon Emissions: Significant annual CO₂ reduction supports climate action goals.

• Lower Maintenance Costs: ALS and TCS technologies extend product lifespan, reducing required maintenance to once per year.

Conclusion

The solar landscape lighting project at this U.S. coastal park represents more than a technological upgrade—it demonstrates the seamless integration of sustainability, aesthetics, and functionality. The SRESKY Honor Series, with its superior adaptability and smart features, showcases the potential of next-generation solar lighting in coastal environments.
