Detailed Component Breakdown:
1. 12W LED Luminary:
It delivers more than 1,500 lumens of bright light. The color temperature ranges between 5500K to 6500K (Cool White), giving excellent night visibility. The heavy-duty aluminum body comes with an IP65 waterproof rating to protect it against heavy rain and dust.
2. 12.8V 30Ah LiFePO4 Battery:
This battery stores 384 Watt-hours of energy. It is highly secure, safe under high temperatures, and offers a long service life of 5 to 7 years (2000+ charge cycles).
3. 75W Solar Panel:
This is a powerful, oversized panel. While a 12W light requires only around 144 Wh for the night, this panel generates over 300 Wh during the day. This ensures that the system works continuously even in winter or during overcast weather.
4. Smart Charge Controller:
It automatically turns the light ON at night and OFF in the morning. It features a smart dimming profile (runs at full brightness for the initial peak hours and dims to 50% past midnight) to preserve battery power.
Pole Height: A 5 to 6-meter rust-free Galvanized Iron (GI) pole is highly recommended for this setup.
