Model: MJ-XJ904

MJ-XJ904 Interstellar II 400W with Arm - Interstellar II series product image
The MJ-XJ904 Interstellar II 400W solar street light with arm uses a Grade A LiFePO4 36Ah battery with 2000 cycles, a 5V/45W monocrystalline solar panel measuring 530 by 400 millimeters, and 90 pieces of 5050 LED chips to deliver 3358 lumens of 6500-7500K illumination. It is designed for main residential roads, medium parking lots, industrial access roads, commercial walkways, and public areas that require stronger coverage than the 200W and 300W models. The 615 by 300 by 80 millimeter die-cast aluminum housing is IP65 rated and provides 2 rainy days of autonomy, with smart light control, remote control, and an optional radar sensor for flexible operation. A thickened cable with an XT60 connector ensures a secure, weather-resistant connection to the solar panel, and the package includes a waterproof cable, arm bracket, remote, and mounting screws. CMJ Solar's Grade A LiFePO4 cells and 2-year warranty ensure reliable service. For distributors and EPC contractors serving mid-sized solar street light projects, the XJ904 is a dependable 400W option. Visit cmjsolar.com for factory-direct wholesale pricing.

Frequently Asked Questions

What warranty do your solar lights come with?

The MJ-XJ904 Interstellar II 400W with Arm 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 MJ-XJ904 Interstellar II 400W with Arm and what area does it cover?

The MJ-XJ904 Interstellar II 400W with Arm produces 3,358 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 MJ-XJ904 Interstellar II 400W with Arm is equipped with Grade A LiFePO4 36Ah and is designed to operate for 2 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 MJ-XJ904 Interstellar II 400W with Arm waterproof and suitable for outdoor use?

Yes. The MJ-XJ904 Interstellar II 400W with Arm 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/45W (530*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.
