We manufacture three models of foldable solar wall lights at our Fujian facility. The defining feature: a hinged monocrystalline solar panel that folds flat for compact shipping, then opens to the optimal charging angle after installation. Every unit includes 4 selectable constant brightness modes and 3 adjustable color temperatures — controlled by a single button.
Our BF-SWL-17 Series series spans 1W to 3.5W, covering entrance gates, perimeter walls, garden paths, stairways, and security fence lines. We ship to property developers, hospitality chains, security contractors, and lighting distributors across 30+ countries. No wiring. No electrician. Surface-mount with 2 screws.
Solar Wall Light Specifications: Complete Model Comparison
All three models share the same industrial design, material construction, and control logic. They differ in size, solar panel wattage, battery capacity, and LED chip count — scaling linearly for different illumination requirements.
| Spec | BF-SWL-17-1W | BF-SWL-17-1.8W | BF-SWL-17-3.5W |
|---|---|---|---|
| Dimensions | 120 × 85 × 38 mm | 155 × 105 × 38 mm | 190 × 125 × 38 mm |
| Solar Panel Power | 5V / 1W Monocrystalline | 5V / 1.8W Monocrystalline | 5V / 3.5W Monocrystalline |
| Battery | 18650 3.7V / 1200mAh | 18650 3.7V / 1800mAh | 18650 3.7V / 2500mAh |
| LED Chips (White) | 2835 (48 pcs) | 2835 (66 pcs) | 2835 (88 pcs) |
| LED Chips (Warm White) | 2835 (32 pcs) | 2835 (44 pcs) | 2835 (66 pcs) |
| Color Temperature | 3000K / 4000K / 6000K | 3000K / 4000K / 6000K | 3000K / 4000K / 6000K |
| IP Rating | IP65 | IP65 | IP65 |
| Operating Temp | -30°C to 60°C | -30°C to 60°C | -30°C to 60°C |
| Material | ABS body + metal bracket + glass reflector cup | Same | Same |
| Modes | 4 brightness modes + 3 color temps | 4 brightness modes + 3 color temps | 4 brightness modes + 3 color temps |
All models use dual-chip LED arrays (white 6000K + warm white 3000K) blended to achieve 4000K neutral white as the third option. The glass reflector cup provides focused downward illumination with minimal light spill.
4 Constant Brightness Modes Explained
Every BF-SWL-17 Series model supports four constant brightness modes, selectable by short-pressing the control button:
| Mode | Brightness | Best For |
|---|---|---|
| Mode 1 | 100% constant brightness | Loading docks, active work areas, security perimeter |
| Mode 2 | 75% constant brightness | Hospitality, ambient perimeter |
| Mode 3 | 50% constant brightness | Garden paths, low-traffic areas |
| Mode 4 | 25% constant brightness | Overnight accent, wayfinding |
Why Constant Brightness Modes: Simplicity That Works
Many solar wall lights rely on motion sensors (PIR or microwave) to manage battery life. Our BF-SWL-17 Series series takes a different approach: 4 selectable constant brightness levels that let you set exactly the output you need, with no sensor complexity, no false triggers, and no dark periods between activations.
| Parameter | Constant Brightness (Ours) | Sensor-Based (Conventional) |
|---|---|---|
| Light Output | Steady, predictable illumination | Fluctuates between standby and full brightness |
| User Control | Choose 100%, 75%, 50%, or 25% | Limited — sensor decides when to activate |
| False Triggers | None — no sensor involved | Common — wind, rain, animals, heat plumes |
| Aesthetic Use | Ideal — consistent ambiance for hospitality, landscaping | Poor — intermittent activation disrupts atmosphere |
| Reliability | Fewer components, fewer failure points | Sensor degradation over time, waterproofing challenges |
| Battery Management | Curve dimming extends runtime smoothly | Sensor standby still draws power, unpredictable runtime |
| IP65 Integrity | Fully sealed — no sensor window needed | Sensor window creates potential moisture ingress point |
