220LM/W Ultra-Bright LED Technology

While standard solar lights range between 130-160LM/W, the BS-FY series utilizes industrial-grade LED chips to achieve a staggering 220LM/W.

Benefit: It provides higher ground illuminance (up to 12,000LM) using the same solar footprint, reducing the number of poles required for your project and lowering overall costs.

Fully Sealed Panel: Anti-Dust & Anti-Moisture

Dust accumulation and internal fogging are the primary causes of light decay in traditional street lights.

The Solution: The BS-FY features a fully sealed die-casting aluminum housing. This design protects the sensitive optical lenses and LED chips from sand, humidity, and salt spray.
Durability: This hermetic seal ensures that the high-brightness performance remains consistent over an 8-year maintenance-free lifespan.

Frequently Asked Questions

Why is a sealed panel necessary for desert environments?

A sealed panel prevents fine sand and dust from entering the optical chamber, which would otherwise coat the LED chips and reduce brightness by up to 50% over time. By maintaining an airtight seal, the BS-FY series ensures the 220LM/W efficiency remains constant regardless of local environmental conditions.

How does the Pro-Double MPPT controller handle extreme heat?

Unlike standard controllers that risk overheating, the BOSUN Pro-Double MPPT is built with industrial-grade components and an optimized heat dissipation structure. It is rated for stable operation at 65°C, ensuring efficient power conversion and battery protection in the world’s hottest regions without the risk of system shutdown.

Why is a sealed panel design important for high-brightness solar street lights?

A sealed panel design protects high-performance LED chips and optical lenses from environmental contaminants like dust, moisture, and salt spray. This ensures the 220LM/W ultra-bright LEDs maintain their luminous flux and prevents internal fogging that can reduce light output.

How does the BS-FY series achieve 220LM/W ultra-high brightness?

The BS-FY series achieves 220LM/W brightness by combining high-efficiency SMD 5054 LED chips with a proprietary Pro-Double MPPT controller. This system optimizes the power-to-lumen ratio, delivering up to 12,000LM of output while minimizing energy waste through superior heat dissipation.
