NVC Solar Outdoor Lighting Floodlight Street Light Remote Control Light Sensor High Brightness 2150lm Coverage 110sqm + Light Control + Remote Control

3. Intelligent Lighting Control & Runtime

• Adaptive light control system with automatic brightness adjustment based on daily solar charge.
• Total lighting time: approximately 10 hours.
• Brightness gradually decreases from 100% to 0% over the runtime to optimize battery usage.
• Data based on laboratory testing; actual runtime depends on environmental conditions.

4. Battery Capacity & Stability

• Uses lithium iron phosphate (LiFePO4) battery cells with over 2000 charge-discharge cycles maintaining >80% capacity.
• High safety standards: no fire risk under puncture, stable under high temperature (-10°C to -50°C).
• Battery capacity examples:
• 1Ah = 1000mAh
• Energy conversion: 1Ah * 1V = 1Wh; e.g., 3.2V 5000mAh = 16,000mWh.
• Data verified by NVC laboratory.

5. Optical Performance

• High-brightness LED chips with luminous efficacy of 220-230 LM/W.
• Lens system includes magnification and refraction layers for focused, high-intensity light.
• Large photovoltaic panel size for efficient solar energy capture.

6. Material & Durability

• Aerospace-grade die-cast aluminum housing for excellent heat dissipation and corrosion resistance.
• Waterproof rating: IP65, suitable for harsh weather conditions including rain and temperature extremes (-50°C to -10°C).
• Long-lasting curved surface LED lens design for enhanced light distribution and coverage without dark spots.

7. Design Features

• Curved large-area luminous surface combining curved screen and high-brightness LED lens for superior illumination compared to traditional flat single-sided screens.
• Energy-saving and environmentally friendly with zero electricity cost annually.
• Five-level charging indicator with flashing lights during charging and steady lights when fully charged.
• High-efficiency monocrystalline silicon solar panels for better conversion efficiency than polycrystalline panels.

8. Smart Solar Charging & Lighting

• Automatic daytime charging and nighttime lighting based on ambient light conditions.
• Full charge achieved with approximately 5 hours of direct sunlight.
• Continuous lighting for about 12 hours on full charge with adaptive brightness control.
• No wiring required; suitable for outdoor courtyards, sports venues, farmhouses, rooftops, etc.

9. Environmental & Usage Data

• Solar irradiance and UV light intensity data vary by region, month, and installation environment.
• Optimal charging occurs between 11:30 AM and 3:30 PM when solar UV intensity is highest.
• Charging efficiency depends on battery capacity, system design, solar panel power, and size.
• Typical outdoor illuminance ranges for charging:
• Direct sunlight: 30,000-50,000 Lux (effective charging)
• Under shade or indoors: below 3,000 Lux (ineffective charging)
• Data sourced from NVC laboratory for user reference.

• Coverage area is maximum recommended; actual coverage depends on installation height and battery charge status.
