LED street light specifications cover performance (lumens, efficacy, wattage), physical build (IP rating, housing, optics), electrical needs (voltage, driver), and smart features (dimming, controls). Key specs include wattage (e.g., 20W-100W+), luminous efficacy (lumens/watt, often 100+ Lm/W), IP66+ rating for weatherproofing, Cool White (5000K-5700K) color, and robust aluminum housing with secondary lenses for optimal light distribution, ensuring safety and energy efficiency. Key Specifications Breakdown Wattage (Power): Ranges from 20W for smaller areas up to 100W or more for main roads (e.g., 72W, 100W, 120W). Luminous Efficacy: Measures efficiency (Lumens per Watt); higher is better (e.g., 100-140+ Lm/W). Lumen Output: Total light output (e.g., 11,000+ Lumens for 100W). Color Temperature (CCT): Typically "Cool Day Light" (5000K-5700K) for better visibility, but warmer options exist (3000K-4000K). Color Rendering Index (CRI): Measures color accuracy; generally >=70 or higher for good distinction. Ingress Protection (IP) Rating: IP66 or higher for dust and water resistance (e.g., IP66). Housing & Optics: Die-cast aluminum with powder coating for heat dissipation, pressure-die-cast, with specialized lenses for wide dispersion. Driver: Built-in electronic driver/control module, often with surge protection. Input Voltage: Wide range (e.g., 90-300V AC). Lifespan: Long life, often >25,000 hours.

A standard solar LED street light features a high-efficiency photovoltaic (PV) module, either monocrystalline or polycrystalline, to charge a maintenance-free battery, often Lithium Ferro Phosphate, during the day. The system includes an LED luminaire, typically cool white (5000-6500K) with an efficacy of over 120 lumens per watt and a lifespan exceeding 50,000 hours.

A 15W LED street light typically offers a luminous efficacy of over 100 lumens per watt, a lifespan of 50,000+ hours, and an IP65/IP66 weatherproof rating. General Specifications Wattage: 15W (system wattage, some variance possible +/- 5%). Lumen Output: Ranges from approximately 1,500 to 2,100 lumens, with efficacy typically between 100-140 lumens per watt. Input Voltage: Most models operate within a wide AC voltage range, commonly 100-275V AC or 90-305V AC. Some solar-integrated models use lower DC voltage (e.g., 12V). Color Temperature (CCT): Typically available in Cool White (around 6500K), though options like 3000K or 4000K are also common. Color Rendering Index (CRI): Generally >70 or >80, providing good color quality. Lifespan: An average operational life of 50,000 to 60,000 hours. Housing Material: Usually made of pressure die-cast aluminum for durability and heat management.
