3-Sided High-Brightness Solar Street Light – 20W to 55W
3-Sided High-Brightness Solar Street Light – 20W to 55W
Wide-Area Solar Lighting With Three-Sided Illumination
The QN-3160 Series solar street light features a distinctive three-sided lamp head that projects light in three directions simultaneously — delivering broader, more uniform coverage than conventional single-face fixtures. Powered entirely by solar energy and backed by a LiFePO4 battery, these lights are engineered for reliable autonomous operation on streets, pathways, parking areas, yards, farms, and commercial outdoor spaces. Choose from five power configurations — 20W, 30W, 40W, 45W, or 55W — to match your project requirements and spacing.
Key Benefits
- Three-Sided Illumination — Projects light in three directions for wider, more uniform area coverage compared to standard single-face designs. Ideal for intersections, wide walkways, and open spaces where a single-direction fixture leaves gaps.
- 160 High-Brightness 5054 LED Packages — Four-chip 5054 LED design delivers efficient, high-output illumination across the full lamp face.
- LiFePO4 Battery Chemistry — Enhanced cycle life, stable discharge performance, and improved thermal safety over conventional lithium-ion batteries.
- Fully Solar-Powered — Integrated solar panel charges the battery during daylight hours; no grid connection or external wiring required.
- Smart Controls Included — Timer remote control and automatic dusk-to-dawn activation enable hands-free, energy-efficient operation without on-site adjustments.
Product Description
The QN-3160 Series integrates a monocrystalline solar panel, a LiFePO4 battery pack, and 160 high-brightness 5054 LEDs into a compact, self-contained outdoor lighting solution. The three-sided lamp head is the defining feature of this series — it simultaneously illuminates in multiple directions, making it particularly effective for path intersections, wide public walkways, open parking lots, and perimeter security lighting.
All five variants share the same robust lamp body (490 × 215 × 90 mm). Panel size and battery capacity scale with the output level, so each configuration is matched to its power demand. The included timer remote gives operators precise control over on/off schedules, while the built-in light sensor ensures automatic dusk-to-dawn activation with no manual intervention required after setup.
Five power options (20W through 55W) allow specifiers and procurement teams to select the appropriate output for each zone of a project, reducing over-specification and optimizing cost per fixture.

Package Includes
- 1 × Solar street light unit (lamp head + integrated solar panel)
- 1 × Mounting bracket
- 1 × Timer remote control
- 1 × Set of expansion bolts and mounting hardware
Installation and Usage
- Site Selection — Choose a location with unobstructed sunlight exposure for the majority of daylight hours. Avoid positions shaded by trees, buildings, or roof overhangs.
- Pole Mounting — Secure the mounting bracket to a suitable pole using the supplied expansion bolts. Confirm the bracket is firmly tightened and the lamp head is positioned for optimal directional coverage.
- Solar Panel Orientation — Angle the solar panel toward the direction of maximum solar exposure for your installation latitude (typically south-facing in the northern hemisphere).
- Initial Charge — Before first use, allow the unit to charge under full sunlight for one complete day to ensure the battery is properly conditioned.
- Timer Remote Setup — Use the included remote to program your preferred on/off schedule. Refer to the enclosed instruction sheet for step-by-step programming.
- Dusk-to-Dawn Operation — The integrated light sensor activates the fixture automatically at dusk and switches it off at dawn. No further configuration is needed for standard automatic operation.
