400W Solar flood light

Given its high wattage, a 400W solar flood light is distinct from integrated solar street lights, often featuring a split-design to optimize performance.

Here’s a breakdown of its typical characteristics:

• Very High Power Output (400W Equivalent): The “400W” typically denotes a very high lumen output (e.g., 20,000 to 40,000+ lumens, depending on efficiency) comparable to a traditional 400W halogen or metal halide floodlight. This ensures powerful, wide-area illumination.
• LED Technology: It utilizes multiple high-efficiency LED chips (e.g., SMD 2835, 3030, or 5050 LEDs) arranged for maximum light dispersion. LEDs offer:
  • Exceptional Brightness: Delivers intense illumination over large areas.
  • Long Lifespan: Typically 50,000+ hours, reducing the need for frequent bulb replacements.
  • High Energy Efficiency: Provides significant light output with relatively low actual power consumption, making it feasible for solar power.
  • Light Quality: Usually produces a crisp, cool white light (6000K-6500K) for enhanced visibility.
• Split-Design Solar System: Unlike “all-in-one” solar street lights, 400W flood lights almost always employ a split or modular design for optimal performance:
  • Separate Solar Panel: A large, high-wattage (e.g., 50W to 100W+) monocrystalline or polycrystalline solar panel is separate from the light fixture. This allows the panel to be optimally angled towards the sun for maximum energy harvest, independent of where the light needs to be pointed.
  • Separate Battery and Controller Box: The high-capacity rechargeable battery (e.g., 3.2V or 12.8V LiFePO4 with capacities ranging from 50AH to 100AH or more) and the smart charge controller are housed in a separate, robust enclosure. This separation allows for larger battery capacity and better thermal management of the electronics.
  • Connection Cable: A heavy-duty, waterproof cable connects the solar panel to the battery/controller box, and another cable connects the battery/controller box to the LED flood light head.
• Robust Casing (Typically Aluminum): While not explicitly stated in “400W Solar flood light,” high-power flood lights almost universally feature a die-cast aluminum casing for the light head itself. This is critical for:
  • Superior Heat Dissipation: Managing the significant heat generated by a high-power LED array is crucial for longevity. Aluminum excels at this.
  • Extreme Durability: Provides robust protection against physical impact, harsh weather conditions, and corrosion, ensuring reliable operation in demanding outdoor environments common in Kenya.
  • High IP Rating: The light head itself will typically have an IP66 or IP67 rating, indicating complete protection against dust and strong jets of water or even temporary immersion.
• Intelligent Control and Automation:
  • Dusk-to-Dawn Operation: Automatic activation at dusk and deactivation at dawn via a photosensor.
  • Remote Control: Nearly always included, allowing users to:
    • Set different lighting modes (e.g., constant brightness, timed operation).
    • Adjust brightness levels.
    • Program working hours.
  • Motion Sensor (Optional/Advanced models): Some high-end models may integrate a motion sensor for even greater energy saving, dimming the light when no presence is detected and brightening it upon motion.
• Long Autonomy: Designed to provide reliable illumination for extended periods, typically 10-12 hours per night, with enough battery capacity for 2-3 cloudy days of autonomy.
