SZLeadray solar street lights set a benchmark for reliable outdoor lighting solutions, boasting three core competitive strengths that cater to the diverse needs of global markets—ultra-long stable battery life, premium Philips LED chips, and customized batwing/rectangular light distribution.
These features ensure consistent performance, superior illumination quality, and adaptability to a wide range of application scenarios, from urban main roads to rural pathways.
1. Ultra-Long & Stable Battery Life: Uninterrupted Lighting Even in Extreme Weather
At the heart of SZLeadray’s reliable operation is its high-performance energy storage system, engineered to deliver extended battery life and stable power supply, even in harsh environmental conditions.
High-Grade Battery Selection: Adopts LiFePO₄ lithium iron phosphate batteries with a cycle life of over 3,000 times, far exceeding the lifespan of conventional lead-acid or ternary lithium batteries. The battery supports deep discharge (≥80% DOD) without memory effect, ensuring long-term capacity stability.
Intelligent BMS Protection: Equipped with a built-in Battery Management System (BMS) that provides four-fold protection against overcharging, over-discharging, overheating, and short circuits. The system also features low-temperature preheating technology, enabling normal charging at -20°C, making it ideal for frigid regions.
Superior Energy Efficiency: Matches the battery capacity with high-efficiency solar panels (conversion efficiency ≥23%) and intelligent dimming functions. This synergy ensures 5–7 days of continuous lighting in rainy or cloudy weather, eliminating concerns about power outages in low-light environments.
2. Premium Philips LED Chips: Brighter, Clearer & Longer-Lasting Illumination
SZLeadray prioritizes lighting quality by using top-tier Philips LED chips, delivering exceptional brightness, color rendering, and durability that meet international standards.
High Luminous Efficacy: The Philips LED chips achieve a luminous efficacy of 160–210 lm/W, ensuring high brightness output with low power consumption. For example, a 60W SZLeadray street light delivers lumen output equivalent to a 200W traditional sodium lamp, reducing energy demand significantly.
Excellent Color Rendering & Anti-Glare Design: With a Color Rendering Index (CRI) ≥80, the lights present true and vivid colors, enhancing visibility and safety for pedestrians and vehicles. The integrated anti-glare micro-prism lens minimizes light pollution, with a Unified Glare Rating (UGR) ≤19, complying with EU EN 13201 road lighting standards.
Ultra-Long Service Life: The LED modules feature an L70 lifespan of over 100,000 hours (approximately 11.5 years of continuous use), ensuring maintenance-free operation for decades and reducing long-term O&M costs.
3. Batwing/Rectangular Light Distribution: Tailored Illumination for Diverse Scenarios
SZLeadray offers two professional light distribution options—batwing and rectangular—to optimize illumination uniformity and coverage, adapting to different road types and application needs.
Batwing Light Distribution: Characterized by a wide, symmetrical light pattern that minimizes light waste at the edges. It is ideal for residential roads, parks, and rural pathways, providing uniform illumination with no dark spots, and ensuring comfortable visibility for pedestrians.
Rectangular Light Distribution: Features a focused, rectangular light pattern that aligns perfectly with the shape of roadways. It is designed for urban main roads, highways, and commercial streets, delivering high illuminance (≥20 lux) and excellent uniformity (≥0.4), meeting the strict requirements of municipal engineering projects.
Customizable Options: Both light distribution designs can be tailored according to customer needs, including adjusting the beam angle (120°–150° for batwing; 90°×160° for rectangular) to match specific installation spacing and height.
These features make SZLeadray street lights suitable for global markets—from European/American municipal projects requiring high light quality to African/Southeast Asian rural roads needing stable battery performance and targeted illumination.
