GH-SLD Core Selling Points & Advantages
1. Monumental "True Full-Power" Output (Up to 200W)
Engineered for Mega Infrastructure: Pushing the boundaries of integrated solar technology, the GH-SLD delivers an incredible maximum output of up to 200W.
High-Mast Superiority: This massive wattage capability produces intense, high-lumen illumination making it perfectly tailored for high-standard highway intersections, shipping ports, and massive public arenas that require mounting heights of 10–15+ meters.
2. High-Efficiency Dual-Head Configuration for Massive Coverage
360-Degree Wide-Angle Distribution: The symmetric dual-head engineering delivers powerful, wide-angle illumination in opposite directions simultaneously. Mounted on high masts, it drastically reduces lighting blind spots and shadows on multi-lane highways or large logistics yards.
3. Externalized Oversized Metal Battery Compartment
Advanced Independent Thermal Management: Fixed strategically directly beneath the solar panel, the massive metal battery vault decouples the power source from the heat generated by the high-wattage 200W LED heads. This creates an optimal cooling environment that prevents thermal degradation.
4. 100% In-House Manufactured LiFePO4 Battery Packs
True Full-Power Autonomy: The oversized vault houses ultra-high-capacity Lithium Iron Phosphate (LiFePO4) battery packs, engineered and manufactured entirely in-house by Guohui Lighting. This guarantees maximum energy density to sustain continuous, high-wattage dual-head output.
