MJ-SF188 16-inch

The MJ-SF188 16-inch comes with a 2-year warranty covering manufacturing defects, the LiFePO4 battery, LED module, and solar panel. Our LiFePO4 batteries are rated for 2,000+ charge cycles, providing 5+ years of expected service life under normal operating conditions. Technical support and spare parts are available throughout the warranty period.

The MOQ is typically 20 units per model for standard products. Sample orders of 1 unit are available for quality evaluation. For OEM/ODM custom packaging, private labeling, or custom color temperatures, the MOQ is 500 units. Contact us for volume pricing and lead times.

The MJ-SF188 16-inch is equipped with Ternary lithium battery 18000mah and is designed to operate for 2-3 rainy days on a full charge. The LiFePO4 battery chemistry provides stable discharge performance even in low temperatures. In regions with extended periods of overcast weather, the light automatically adjusts brightness via the intelligent controller to conserve battery while maintaining basic illumination.

Yes. The MJ-SF188 16-inch carries an IP65 rating, meaning it is completely dust-tight and protected against water jets from any direction. This makes it suitable for year-round outdoor use in rain, snow, and dusty environments. The housing is constructed from corrosion-resistant materials to withstand UV exposure and extreme temperatures. We do not recommend submerging the fixture, as IP65 is not an immersion rating.

Under standard sunlight conditions (1000W/m2 irradiance), the 9V/22wMonocrystalline Grade A panel 400*350mm fully charges the battery in approximately 4-8H. The actual charging time varies based on geographic location, season, panel tilt angle, and weather conditions. The MPPT or smart charge controller maximizes energy harvest even in partial cloud cover.
