## SPL-4104 Pumpkin Solar Pillar Top Light

IP65 Weatherproof · Fluted Diffusive Optics · 4.5W Monocrystalline PV · Self-Contained Unit (External Tall Pole Excluded)

The SPL-4104 Pumpkin Series Solar Pillar Top Light brings organic fluted elegance and crystalline perimeter wash to exterior boundary walls, gate posts, balustrades, and courtyard piers. Featuring an iconic fluted optical chamber, it projects a broad 360-degree perimeter pool across pedestrian walkways and deck perimeters without blinding upward glare. Powered by a top-mounted 4.5W 5V monocrystalline solar module, a high-capacity 3.2V 7Ah (22.4Wh) LiFePO4 battery pack, and smart dusk-to-dawn PWM energy management, the luminaire delivers over 3 consecutive rainy nights of reliable autonomy. Complete self-contained pier-mount luminaire; external tall street lighting poles are excluded.

## Advantages

### Fluted Diffusive Optical Chamber

Classic pumpkin fluted PC diffuser softens directional LED light, creating a comfortable 360-degree radial illumination pool without upward glare.

### 4.5W Monocrystalline PV Disc

Integrated circular monocrystalline module maximizes sunlight conversion efficiency, fully recharging the battery in 4 to 6 hours of bright sunlight.

### High-Capacity 7Ah LiFePO4 Battery

Heavy-duty 3.2V 7Ah (22.4Wh) Grade-A Lithium Iron Phosphate chemistry provides over 2,000 charge cycles and 3+ overcast nights of reserve runtime.

### Marine-Grade Die-Cast Aluminum

Robust die-cast aluminum housing finished with architectural powder coating provides superior corrosion resistance against coastal salt spray.

### Dual Power Architecture Available

Offered in both standalone 100% solar autonomous configuration and hardwired AC mains version for flexible commercial landscape specification.

### IP65 Ingress & Dustproof Sealing

Precision silicone gasket sealing ensures uninterrupted operation in heavy rainstorms, coastal humidity, and extreme temperatures from -25°C to +65°C.

## Applications

### Boundary Wall Piers & Entry Gates

Defining estate entrance gates, perimeter walls, and brick pillars with crisp geometric presence and zero conduit trenching.

### Balustrades & Deck Railing Posts

Mounting atop outdoor patio balustrades, deck handrail pillars, and terrace parapets with gentle downward ambiance.

### Riverside & Waterfront Promenades

Illuminating waterside boardwalks, canal railings, and decorative stone bollards with reliable IP65 weather sealing.

### Courtyard & Garden Terrace Pillars

Enhancing outdoor dining verandas, stone garden walls, and hotel lounge courtyards with warm, welcoming illumination.

### Commercial Campus & Plaza Columns

Providing clean, minimalist architectural aesthetics that complement corporate campus pathways and commercial pavilions.

### Rooftop Terraces & Sky Gardens

Delivering self-powered solar illumination to high-rise amenity decks and rooftop gardens where electrical wiring is difficult.

## FAQ

What mounting interface is used for the SPL-4104 pillar top light?

The SPL-4104 features an integrated Ø150mm circular mounting flange with pre-drilled anchor bolt holes designed for secure fastening onto concrete piers, masonry pillars, brick walls, and timber deck posts. External tall street light poles are excluded; this is a standalone column luminaire. How does the SPL-4104 perform during prolonged cloudy or rainy periods?

Powered by a high-capacity 3.2V 7Ah (22.4Wh) Grade-A LiFePO4 battery pack and intelligent PWM power management, the SPL-4104 maintains over 3 continuous cloudy or rainy days (3+ full nights) of illumination without supplementary sunlight charging. Where is the CAD engineering blueprint for the SPL-4104 located?

Because the SPL-4104 is an engineered single-model architectural pillar light, its official CAD dimension blueprint is featured directly in the Product Overview media preview above for immediate architectural reference. Are both solar autonomous and AC mains hardwired versions available?

Yes. Projects requiring 100% off-grid operation can specify the solar autonomous model with integrated 4.5W monocrystalline disc, while applications with existing electrical conduit can select the AC hardwired 100-240V model with matching aesthetics.
