Rechargeable Solar street light 400w & 500w
High-power Rechargeable LED Solar Street Lights (400W & 500W) are heavy-duty, industrial-grade lighting solutions designed for large open areas. Typically built as "All-in-One" (integrated) or split-panel designs, they provide massive coverage without requiring any electrical wiring, relying entirely on the sun to charge their high-capacity internal batteries.
Here is a detailed product description breaking down the features and differences between the 400W and 500W models.
## Core System Features (Both Models)
-
Smart Dusk-to-Dawn Automation: Automatically turns on at sunset and shuts off at sunrise to recharge.
-
PIR Motion Sensor (Radar Control): To preserve battery life, the light stays at a dimmed energy-saving mode (around 30% brightness) when the area is empty, and immediately boosts to 100% full brightness when it detects human or vehicular movement.
-
IP65/IP66 Weatherproofing: Housed in heavy-duty die-cast aluminum or high-impact ABS material, completely sealed against torrential rain, dust, and extreme heat.
-
LiFePO4 Lithium Batteries: Equipped with Lithium Iron Phosphate batteries, which offer a vastly superior lifespan (over 5 to 8 years) and better thermal stability than old-school lead-acid batteries.
-
Full-Function Remote Control: Includes a remote to override the automated settings, manually force the light ON/OFF, adjust constant brightness levels, or set timers (e.g., 2, 3, or 4 hours).
## 400W vs. 500W Specification Comparison
While both lights look similar, the 500W model utilizes a larger solar footprint, a higher battery storage capacity, and denser LED arrays to throw light over a wider area.

## Applications & Use Cases
-
400W Model: Ideal for large residential driveways, private farmhouses, perimeter security walls, garden pathways, and school/college courtyards.
-
500W Model: Best suited for high-demand commercial environments, including public roadways, commercial parking lots, construction sites, factory perimeters, and sports fields.
Installation Note: Most packages include the necessary wall-mounting arm or pole brackets. Ensure you mount these lights in a location that gets unshaded, direct sunlight for the entirety of the afternoon to achieve maximum nighttime performance.
