DeltaS vs. Conventional Streetlights: Technical Analysis
When comparing DeltaS split solar streetlights to conventional grid-dependent streetlights, several key differences are immediately apparent. Let’s analyze the three key performance indicators: energy efficiency, durability, and smart innovation.
1. Energy Efficiency: Zero Grid Dependency, Maximum Savings
Energy efficiency is a key factor in modern infrastructure, especially as businesses and local governments seek to reduce operating costs. While traditional grid-powered streetlights suffer from high energy consumption and fluctuating electricity prices, DeltaS solar streetlights are powered by renewable energy and optimized for power usage.
| Standard Conventional Streetlight | DeltaS Solar Streetlight |
|---|---|
| Power supply | Grid-dependent and cost-unstable |
| LED efficiency | ≤120 lm/W |
| Daily operation | Fixed brightness, wasteful energy |
| Efficiency | Lower efficiency |
The DeltaS uses 230 lm/W LEDs to provide up to 15,000 LM of brightness while consuming 50% less power (SSL-815S model). This significantly reduces energy costs, making the DeltaS series an environmentally friendly solution that saves both money and energy.
In addition, the ALS2.4 Adaptive System automatically adjusts brightness in response to changes in ambient light, reducing idle energy consumption by 40%. This feature not only ensures that the luminaire provides adequate illumination but also saves energy when full brightness is not required.
2. Durability: Adapting to Extreme Conditions
Durability is crucial for any outdoor lighting system. Traditional luminaires are susceptible to damage from extreme weather conditions (e.g., extremely hot or cold weather, flooding), resulting in high repair and replacement costs. In contrast, DeltaS streetlights are designed to cope with extreme weather and ensure reliable long-term performance.
| Standard Conventional Streetlights | DeltaS Solar Streetlights |
|---|---|
| Waterproof and dustproof | Corrosive and susceptible to water damage |
| Temperature range | Extreme hot/cold weather susceptible to damage |
| Life expectancy | 3-5 years (frequent repairs) |
DeltaS streetlights are IP65/IK08 rated, dustproof, waterproof, and impact-resistant for use in harsh environments. Whether installed in deserts, coastal areas, or cold regions, DeltaS luminaires are able to operate stably over a temperature range of -20°C to 60°C.
In addition, the DeltaS series‘ Li-Ion batteries are designed to last more than 10 years, which is three times longer than conventional streetlight systems. Its Battery Management System (BMS) further extends battery life by 30% through protection against overcharging, short-circuiting, and overheating.
3. Smart Innovation: Control at Your Fingertips
The smart technology of the DeltaS Solar Streetlight sets it apart from traditional lighting systems, which typically offer limited functionality.
| Standard Conventional Streetlight | DeltaS Solar Streetlight |
|---|---|
| Control | Manual on/off |
| Adaptive | Fixed lighting |
| Maintenance | Passive troubleshooting |
DeltaS Solar Streetlight is equipped with a PIR motion sensor (120° angle, 12-meter range) for precise management of energy consumption. The luminaire reaches 100% brightness only when motion is detected, significantly reducing idle energy consumption. In addition, the rain sensor automatically adjusts the light color from 5700K (cool white) to 3000K (warm white) during rainy days, ensuring that it still provides good visibility during heavy rain.
ALS2.4 technology intelligently adjusts brightness according to ambient light and weather changes, while a real-time troubleshooting system allows remote monitoring and problem-solving via the LED screen, improving maintenance efficiency and reducing downtime.
DeltaS Technical Specifications: Precision is
Critical
Below are key specifications for the DeltaS series to help you choose the right model for your project needs:
| Model | Brightness | Mounting Height / Pitch |
| SSL-86S | 6000LM | 6m / 20m |
| SSL-88S | 8000LM | 8m / 22m |
| SSL-810S | 10,000LM | 10m / 26m |
| SSL-812S | 12,000LM | 12m / 28m |
| SSL-815S | 15,000LM | 15m / 31m |
Core Features
- LED Configuration: Dual Color Temperature (3000K/5700K, Ra70) Adaptive Visibility.
- Battery Management: 18V Li-Ion battery, fast charging (4.8-6 hours).
- Rainy Day Performance: 3+ days of runtime in M1 mode, even in heavy rain.
- Materials: Aircraft-grade aluminum alloy and polycarbonate ensure lightweight and durability.
Wholesaler Value: Why DeltaS Stands Out in 2025
DeltaS Split Solar Street Lights offer exceptional value to wholesalers and B2B customers, making them ideal for bulk purchases and large-scale projects:
- Higher Profits: Lower installation and maintenance costs result in higher profits for wholesalers.
- Customizable Scalability: The DeltaS Series is available in a wide range of models from 6,000LM to 15,000LM for different scenarios such as highways, industrial areas, and parks.
- Sustainable Compliance: Carbon-neutral lighting solutions help companies meet Global ESG (Environmental, Social, and Governance) standards.
- Smart City Integration: Designed to support IoT technologies, ensuring long-term relevance and readiness for infrastructure upgrades.
