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 has five modes — an automatic microwave-sensor mode plus four constant brightness levels — and three color temperatures, all from a single button.
Our BF-SWL-17 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 | Microwave auto + 4 constant levels, 3 color temps | Microwave auto + 4 constant levels, 3 color temps | Microwave auto + 4 constant levels, 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.

Five Modes: Microwave Sensor Plus Four Constant Levels
Every BF-SWL-17 Series model has five modes, selected by short-pressing the control button:
| Mode | Behaviour | Best For |
|---|---|---|
| Mode 1 | Microwave auto — 100% when someone is in range, 15% standby when nobody is | Side gates, service paths, stairways, anywhere traffic is intermittent |
| Mode 2 | 100% constant | Loading docks, active work areas, security perimeter |
| Mode 3 | 75% constant | Hospitality, ambient perimeter |
| Mode 4 | 50% constant | Garden paths, low-traffic areas |
| Mode 5 | 25% constant | Overnight accent, wayfinding |
Constant modes (2-5) use curve dimming — the controller eases output down as battery voltage drops instead of cutting off abruptly, which extends effective runtime and avoids the sudden blackout common in cheaper solar lights.
Color temperature: long press cycles 3000K → 4000K → 6000K. Microwave night-light: double-click turns the sensor function on or off. The light retains your last mode and color temperature after each power cycle.
Sensor Mode or Constant Mode? When to Use Each
The same fixture does both, so the choice is per location rather than per product.
| Situation | Set It To | Why |
|---|---|---|
| Side gate, service path, back stairway — people pass a few times a night | Mode 1 (microwave auto) | 15% standby between visitors is the lowest draw of any mode, so runtime through a cloudy week is longest |
| Hotel walkway, entrance feature wall — the light is the ambiance | Mode 3 or 4 (75% / 50% constant) | Steady output; a light that jumps to full brightness whenever a guest walks past reads as a fault, not a feature |
| Security perimeter, loading dock — continuous coverage required | Mode 2 (100% constant) | Cameras and patrols need an unbroken light level, not a sensor deciding when to activate |
| Wall next to moving foliage or a busy road | Constant mode | Microwave sensing responds to motion, and swaying branches or passing traffic in range will keep waking the light |
Microwave sensing works through the sealed housing — there is no separate sensor window to seal — and it responds to movement rather than body heat, so it is unaffected by hot-weather glare that troubles PIR units. The trade-off is the one in the last row: it cannot tell a person from a moving bush. For the engineering behind the two sensor types, see PIR vs microwave sensor solar lights.

Which Model Fits Your Project?
The three models serve different scale requirements within the same application types. Use this table as a starting point — then contact our team for project-specific recommendations.
| Application | Recommended Model | Color Temp | Mode | Why This Configuration |
|---|---|---|---|---|
| Residential entrance gates | BF-SWL-17-1.8W or BF-SWL-17-3.5W | 3000K (warm) | Mode 3 (75%) | Welcoming ambiance with balanced brightness and runtime |

| Hotel / resort walkways | BF-SWL-17-1.8W | 3000K (warm) | Mode 4 (50%) | Consistent warm glow, hospitality-grade atmosphere |
| Garden paths and borders | BF-SWL-17-1W | 4000K (neutral) | Mode 1 (microwave auto) | Lights up on approach, 15% standby stretches runtime; compact size blends with landscaping |
| Stairways and steps | BF-SWL-17-1.8W | 4000K (neutral) | Mode 3 (75%) | Safety illumination, neutral tone for true color rendering |
| Parking area fence lines | BF-SWL-17-3.5W | 6000K (cool) | Mode 2 (100%) | Maximum constant output, high output per unit |
| Construction site perimeter | BF-SWL-17-3.5W | 6000K (cool) | Mode 2 (100%) | Maximum constant output, zero wiring for temporary sites |
| Residential development (bulk) | BF-SWL-17-1.8W | 3000K (warm) | Mode 4 (50%) | Cost-to-performance sweet spot for 200-2000 unit orders |
