Driven by global tourism trends and sustainable development, solar lighting technology has become an ideal choice for high-end resorts seeking to enhance nighttime experiences and strengthen their green credentials. As a leading brand in solar street lighting, SRESKY provided an efficient, eco-friendly illumination solution for Vietnam’s Lotus Resort Cam Ranh through its Atlas Series integrated solar street lights. The project successfully deployed 380 units across the resort’s main streets and public areas, enhancing safety and aesthetics while achieving zero-carbon emission goals.
I. Project Background and Needs Analysis
1.1 Project Background
Cam Ranh City, Vietnam, renowned for its pristine beaches and tropical landscapes, has become a fast-growing tourism hotspot. As a premier leisure destination, the Lotus Resort Cam Ranh offers luxury accommodations, dining, and water sports facilities, attracting hundreds of thousands of visitors annually. However, inadequate nighttime lighting limited the resort’s evening appeal. Poorly lit streets and public areas increased risks of falls and safety incidents while restricting opportunities for nighttime activities such as starlit dinners and seaside walks.
Traditional grid-connected lighting posed challenges: cable installation across difficult terrain cost up to $150,000 per kilometer, with construction periods extending for months. High electricity and maintenance costs further increased the burden. Additionally, reliance on the grid conflicted with the resort’s sustainability goals. The project client, Cát Lạc Lotus Resort, sought to create a safe, visually appealing, and sustainable nighttime environment through modern lighting upgrades. Leveraging its track record across 3,500+ international projects, SRESKY emerged as the preferred partner, tasked with deploying 380 solar streetlights covering approximately 5 kilometers of pathways and public areas.
1.2 Core Requirements and Challenge Analysis
Field research identified four key requirements for the project, typical of tropical tourism facilities:
-
Large-Scale Deployment: Installation of 380 streetlights covering roads, walkways, dining areas, and leisure zones. Brightness levels needed to range from 2000LM to 10000LM to suit various scenarios.
-
High Technical Adaptability: Cam Ranh’s tropical monsoon climate features 28–35°C temperatures, humidity above 80%, and annual rainfall of 2000mm. The lighting system required IP65 waterproof/dustproof protection, IK08 impact resistance, resistance to salt fog and UV corrosion, and a lifespan of over 5 years.
-
Energy Efficiency & Environmental Protection: Use of clean energy to achieve zero electricity costs and reduce carbon emissions. Annual reductions needed to exceed several dozen tons while minimizing light pollution to protect nocturnal ecosystems.
-
Aesthetic Harmony: A modern, sleek design that complements palm trees and coastal landscapes, with installation heights of 3–10 meters and spacing of 15–32 meters.
The SRESKY Atlas Series met all these requirements, offering the reliability, aesthetics, and sustainability needed for a high-end resort environment.

-
High Protection & Modular Design: IP65 waterproofing, IK08 impact resistance, and corrosion-resistant aluminum alloy + PC body. Components can be replaced in under 20 minutes by a single operator.
III. Project Implementation & Execution
The project was completed in under three weeks, minimizing disruption to resort operations.
3.1 Planning and Design
Spacing, height, and positioning were precisely calculated using lighting simulation software. For example, SSL-32A models were used on narrow paths (15m spacing), while SSL-38A/310A covered wider roads (28–32m spacing).
3.2 Logistics and Transportation
Streetlights and accessories were shipped via sea freight with moisture-proof, impact-resistant packaging. Equipment arrived intact with zero transport losses.
3.3 Commissioning and Operation
Each luminaire underwent functional testing. A 1.5-second press confirmed ALS, PIR, and lighting modes. LED indicators (Red <30%, Orange 30–70%, Green >70%) displayed battery status, ensuring full operational coverage.
IV. Project Outcomes and Impact
4.1 Social Value
-
Enhanced Safety: 380 lights provided uniform illumination, reducing accident risks by 30%. Guests could stroll and dine safely at night.
-
Improved Nighttime Experience: Lighting created an inviting atmosphere, blending with palm trees and coastal scenery to enhance vacation appeal.
-
Boosted Nighttime Economy: Bright lighting increased participation in evening events, raising nighttime revenue by 15%.
4.2 Economic & Environmental Benefits
-
