Breaker 300W MJ-BW300 - Breaker series product image
The Breaker 300W solar flood light (model MJ-BW300) steps up output for larger residential and light-commercial properties, using a Grade A LiFePO4 30Ah battery, a 5V/40W monocrystalline solar panel, and 91 pieces of 5054 LED chips to generate 2178 lumens of 6500-7500K daylight. This 300W fixture is a popular choice for driveways, farmyards, small warehouse yards, shop fronts, and community pathways where the 100W and 200W models would leave dark spots. The unit runs for 2 to 3 rainy days on a full solar charge and is controlled by an intelligent system that combines automatic dusk-to-dawn light control, a handheld remote for mode selection, and a radar motion sensor that triggers full brightness when people or vehicles approach. The 311 by 264 by 55 millimeter housing is IP65 rated for years of outdoor exposure, and the package includes a 3-meter waterproof cable, U-bracket, remote, and screws. CMJ Solar's LiFePO4 cells deliver 2000 cycles and are backed by a 2-year warranty. For distributors stocking a graduated range of solar flood lights, the 300W Breaker fills the high-volume mid-power segment. Factory-direct wholesale pricing and OEM customization are available at cmjsolar.com from CMJ Solar's Jiangmen, Guangdong facility.

Frequently Asked Questions

What warranty do your solar lights come with?

The Breaker 300W MJ-BW300 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.

What is the MOQ for solar lights?

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.

How bright is the Breaker 300W MJ-BW300 and what area does it cover?

The Breaker 300W MJ-BW300 produces 2,178 lumens of light output. For reference, this level of brightness is suitable for large areas such as parking lots, roadways, and commercial perimeters. The recommended mounting height varies by application for optimal light distribution.

How many rainy or cloudy days can the light operate without sunlight?

The Breaker 300W MJ-BW300 is equipped with Grade A LiFePO4 30Ah 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.

Is the Breaker 300W MJ-BW300 waterproof and suitable for outdoor use?

Yes. The Breaker 300W MJ-BW300 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.

How long does it take to fully charge the battery?

Under standard sunlight conditions (1000W/m2 irradiance), the Grade A Monocrystalline 5V/40W (480*400mm) fully charges the battery in approximately 6-8 hours. 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.
