Core Electrical Specs

• LED Power: 12 Watt
• Battery Type: LiFePO4 (Lithium Iron Phosphate)
• Battery Voltage: 12.8V
• Battery Capacity: 12Ah
• Total Battery Energy:

12.8V × 12Ah = 153.6Wh

This battery size is commonly paired with 12W systems and is widely listed with 65W solar panels and dusk-to-dawn control. 

Battery Performance

Approx backup:

• Full power continuous: ~12 hours ideal (real-world depends on controller dimming)
• With auto dimming/PIR: 13–15 hours typical
• Autonomy: Usually 1–2 rainy days depending on discharge settings

Standard Battery Parameters

• Charge Voltage: 14.4V max
• Low Cutoff Voltage: 10V–11.2V
• Cycle Life: ~2000+ cycles (about 5+ years if quality cells)
• BMS Protection: Overcharge / Deep discharge / Short circuit / Reverse polarity

Solar Panel Match

Recommended:

• 65W Mono panel (most common)
• Charging time:

6–8 hours good sunlight

Light Output

If LED efficacy is:

• 120 lm/W → ~1,440 lumens
• 150 lm/W → ~1,800 lumens

Typical commercial range is around 1,500–2,000 lumens.

Pole & Installation

• Pole Height: 4–5 meters
• Pole Distance: 8–10 meters
• Application: Village roads, society lanes, pathways, gardens

SHAGSUN Practical Recommendation:

Best balanced specification:

12W LED + 12.8V 12Ah LiFePO4 + 40W Mono Solar Panel

Realistic Output:

• 1500–1800 lumens
• 12–15 hrs backup
• 2–5 year battery life (depends on cell grade)
