High-Efficacy All-in-One Solar Street Light
As a leading integrated solar street light supplier, we engineer outdoor lighting systems that bridge the gap between high luminous output and extreme cost-efficiency. Designed specifically for demanding engineering procurement, the DT-GX40 and DT-GX50 series offer heavy-duty, commercial solar street lights tailored for B2B applications, municipal tenders, and large-scale industrial park solar lighting solutions.
By upgrading to an advanced 180 LM/W optical matrix and a decentralized smart thermal management architecture, these fixtures slash overall project costs while guaranteeing continuous roadway safety under unpredictable weather conditions.
Key Performance Advantages
180 LM/W High Efficacy Solar Street Light Technology
Unlike standard retail fixtures that run at lower efficiencies, this series utilizes premium SMD3030 chips (120pcs) delivering an ultra-high luminous efficacy of 180 LM/W. For project developers, this means maximum target lux levels are achieved with a surprisingly compact 40Wp or 50Wp photovoltaic module, reducing wind-load issues and heavy pole requirements.
Extended 3-5 Rainy Days Backup Autonomy
Unreliable grid infrastructure or extended monsoon seasons require a robust solar pathway lights setup. Equipped with a built-in 3.2V LiFePO4 battery (available in 40Ah and 50Ah capacities), our smart controller regulates depth-of-discharge dynamically. The system effortlessly delivers a standard 12-hour daily operation, backed by 3 to 5 rainy days backup autonomy to ensure Zero-Blackout municipal operations.
Industrial-Grade Durability and Seamless Retrofitting
Constructed from structural die-cast aluminum alloy, the anti-corrosion chassis doubles as an integrated heat sink to maximize battery and LED driver lifespan. Weighing between 8.8 KG and 9.2 KG, the unified housing features a standardized 60mm bracket diameter. This allows rapid installation on existing standard poles, streamlining municipal solar street lighting supplier supply chains and lowering on-site labor overhead.

Engineered Batwing Light Distribution
When evaluating commercial solar street lights for large-scale tender requirements, the efficiency of the optical system is just as critical as battery capacity or solar panel wattage. Standard spherical lenses scatter light symmetrically, wasting a significant percentage of lumens outside the target roadway and causing hot-spots directly underneath the pole.
Financial and Architectural Impacts for EPC Contractors
For municipal planners and project developers, the primary advantage of batwing light distribution lies in the optimization of pole spacing. Traditional outdoor fixtures often require tight spacing to prevent dark gaps between coverage zones.
By utilizing our engineered optical matrix, the effective coverage area of each fixture is significantly wider, extending the recommended pole interval to 20–30 meters.
Lower Capital Expenditure (CapEx): Spacing poles further apart means fewer total fixtures are required to illuminate the same kilometer stretch of highway or industrial perimeter.
Reduced Civil Works Overhead: Fewer poles translate directly to a reduction in concrete foundation pouring, trenching, and installation labor hours on-site.
FAQ
Q: What is the Color Rendering Index (CRI) of the 6500K cool white daylight option?
A: Our standard 6500K fixtures feature a CRI of 70, which is the industry standard for optimal visibility and peripheral contrast on public roadways and highway projects.
Q: Since these are polycrystalline solar panels, how do they ensure a full charge within 8 hours of sunshine?
A: We use high-conversion efficiency polycrystalline cells packaged with high-transmittance tempered glass to maximize solar irradiance absorption. The 40Wp/50Wp sizing is mathematically matched to the battery's capacity, ensuring that even under standard peak sun hours, the system achieves a full charge within the designated 8-hour window.
Q: What is the IP and IK impact rating of the die-cast aluminum alloy housing?
A: The housing is rated at IP65 for ingress protection, ensuring complete sealing against dust and heavy rain. The structural die-cast aluminum chassis provides an IK08 impact rating.
Q: Are the battery and smart controller field-replaceable?
A: The unit is designed with a modular interior layout. Both the LiFePO4 battery pack and the smart controller are accessible via a dedicated maintenance panel secured by screws. This allows field technicians to easily swap out individual components on-site without removing the entire fixture arm or scrapping the housing.
Q: What certifications do the DT-GX40 and DT-GX50 series hold for international compliance?
A: The fixtures carry CE, RoHS, and IP65 certifications. Additionally, the integrated LiFePO4 batteries carry UN38.3, MSDS, and relevant transport safety certifications, making them fully compliant with international hazardous goods shipping standards.
