The Ultimate High-Power Solar Street Light for Large-Scale Infrastructure Projects
The UT-60-042 series, known as the XC series, represents the pinnacle of OKELI‘s solar street light engineering — delivering extraordinary power from 400W to an industry-leading 1000W. These grey die-cast aluminum fixtures are designed for the most demanding infrastructure projects: highways, major roadways, industrial zones, ports, large commercial complexes, and municipal public spaces. With 100 lumens per watt efficiency and 6500K cool white color temperature, these fixtures deliver maximum brightness and visibility for large-scale outdoor environments where reliability and performance are non-negotiable.
Massive Solar Energy System for Demanding Applications
Each unit in the UT-60-042 series is equipped with a high-capacity 3.2V LiFePO4 battery and a high-efficiency monocrystalline silicon solar panel. The system configuration scales with power requirements:
400W (UT-60-04201): 3.2V/25Ah battery, 6V/30W solar panel, 590×340×45mm, 300 LEDs
600W (UT-60-04202): 3.2V/40Ah battery, 6V/50W solar panel, 825×340×45mm, 300 LEDs
800W (UT-60-04203): 3.2V/50Ah battery, 6V/60W solar panel, 1165×340×45mm, 400 LEDs
1000W (UT-60-04204): 3.2V/60Ah battery, 6V/80W solar panel, 1395×340×45mm, 500 LEDs
With 5-6 hours of charging time and 12-24 hours of working time per full charge, these lights provide reliable overnight illumination even during extended cloudy periods.
Superior LiFePO4 Battery Technology
The 32700 LiFePO4 (Lithium Iron Phosphate) battery cells represent a technology borrowed from the electric vehicle and commercial energy storage industries. Unlike standard lithium-ion batteries that degrade rapidly when exposed to extreme temperature swings in outdoor enclosures, LiFePO4 chemistry offers several critical advantages:
Thermal Runaway Prevention: LiFePO4 chemistry is intrinsically safe. Even when the black aluminum housing reaches high internal temperatures under direct sun, the battery will not swell, vent, or catch fire
Superior Cycle Life: LiFePO4 delivers 2,000 to 3,000 full discharge cycles — translating to 6-8 years of reliable service before battery replacement is even a consideration
Depth of Discharge Tolerance: LiFePO4 can be deeply discharged to nearly 90-100% of its rated capacity without permanent damage
The True Cost Advantage of Solar-Powered Street Lighting
When comparing solar street lights to traditional AC-powered alternatives, the total cost of ownership tells a compelling story. Installing traditional AC street lights in remote locations requires trenching and laying armored cable — costing anywhere from $15 to $50 per meter depending on terrain. A typical street light running 12 hours a night consumes significant electricity, adding up to over 1,300 kWh per year in electricity costs per fixture. The UT-60-042 series eliminates these expenses entirely. With zero trenching costs, zero electricity bills, and minimal maintenance requirements, the total cost of ownership is dramatically lower than traditional AC solutions.
Premium Die-Cast Aluminum Construction
The UT-60-042 series features a rugged grey die-cast aluminum housing that provides exceptional durability and thermal management. Die-cast aluminum offers several advantages for outdoor street lighting applications:
Superior heat dissipation: Maintains optimal LED temperatures for extended lifespan
Excellent corrosion resistance: Suitable for coastal and high-humidity environments
Lightweight yet robust: Easy to install while providing excellent protection
Professional appearance: Grey finish complements any architectural style
Sustainable Off-Grid Lighting for Infrastructure Projects
By eliminating the need for grid electricity, the UT-60-042 series significantly reduces operational costs and carbon footprint. The automatic dusk-to-dawn operation ensures hands-free performance, while the 2-year warranty provides peace of mind for long-term investment. The zero electricity bills and easy installation make this series an excellent choice for large-scale infrastructure projects.
OEM/ODM Customization Available
OKELI offers comprehensive OEM/ODM customization services for the UT-60-042 series, including custom wattages, color temperatures, housing colors, branding, and packaging. With certifications including CE, CB, ROHS, TUV, VDE, SAA, ETL, and BIS, OKELI ensures each product meets international standards and customer specifications.
