25W Solar Street Lights built with Lithium Iron Phosphate (LiFePO4) batteries are high-efficiency, durable, and cost-effective lighting solutions. The integration of LiFePO4 chemistry represents a massive upgrade over older Lead-Acid or standard Li-ion batteries due to its safety, thermal stability, and long cycle life.
Key Technical Specifications & Features
When looking for a 25W Solar Street Light with LiFePO4 battery, these are the standard industry specifications you should expect:
- LED Wattage & Output: Driven at a highly efficient 25W output. Quality fixtures feature high-efficacy LED chips (like OSRAM, Epistar, or Bridgelux) that deliver 130 to 150 lumens per watt.
- Battery Chemistry (LiFePO4): Typically rated at 12.8V / 24Ah (or 3.2V equivalent of high capacity like 20,000mAh+). It provides 2,000+ charge cycles and can easily last 5 to 8 years.
- Solar PV Panel: Paired with a 30W to 75W Monocrystalline panel to ensure efficient charging even under cloudy skies.
- Intelligent Controls: Standard systems use a built-in MPPT/PWM controller. They operate on an automatic Dusk-to-Dawn sensor combined with a PIR or Radar motion sensor (which dims the light to 10%–20% when no motion is detected to conserve the battery for a 12 to 16-hour backup).
