Facade Lighting Project

Square Shape Half Mask LED Underground Light

The FD-U140R03 is a 3W square-shaped half-mask in-ground LED luminaire designed for architectural and landscape lighting projects requiring a compact, recessed fixture with a clean, minimal profile. The fixture features a square aluminium body with a half-mask cover that allows light to project in a controlled direction while maintaining a low visual profile above ground. It operates on DC12V or DC24V, making it suitable for low-voltage systems common in landscape and facade applications. The IP67 rating ensures reliable performance in paved areas exposed to rain and temporary water immersion.

Benefits

Key Benefits

Compact size fits into tight spaces where larger fixtures cannot be installed
Half-mask design provides directional light output while reducing visual bulk
IP67 rating supports installation in paved areas subject to standing water after rain
DC12V or DC24V input matches low-voltage site wiring commonly used in landscape projects
No driver supplied allows integration with centralised or distributed driver systems
Aluminium body provides efficient heat dissipation in confined recessed positions

Where It Is Used

Application Scenarios

Marking edges of pedestrian pathways and garden beds in residential and public landscapes
Highlighting architectural details such as stone joints or wall transitions in facade lighting
Lighting steps and access points in low-voltage landscape schemes with limited space
Installing in paved courtyards and plazas where a flush, low-profile fixture is required

Buyers

Who It Is For

Facade and landscape lighting contractors installing in-ground lights in hardscape with space constraints
Lighting designers specifying compact, low-profile fixtures for aesthetic integration
Electrical wholesalers supplying architectural lighting components for European and Middle Eastern projects
Brand owners sourcing OEM in-ground luminaires under their own label with custom branding

Why It Matters

Problems It Solves

Large in-ground fixtures require deep or wide pits, increasing civil works and cost
Full-mask fixtures create a higher visual profile above ground, disrupting clean lines
Fixtures with built-in drivers increase complexity when centralised driver systems are used
Non-IP67 rated units fail in areas with frequent rain or temporary flooding

Comparison

Compared With the Alternatives

Full-mask in-ground light

Lower visual profile, better for clean architectural lines, but may require higher power to achieve same light output

Larger in-ground fixture

Requires deeper or wider cut-out, increases civil works, but may offer higher lumen output

Mains-voltage in-ground light

Simpler wiring but requires higher safety measures; DC12/24V version avoids high-voltage risks in wet areas

Installation

Use Guide

Cut a D34 mm hole in the paving with proper drainage below the fixture
Install the fixture flush with the finished paving surface to avoid trip hazards
Connect to a DC12V or DC24V power supply, ensuring cable size accounts for voltage drop
Use a centralised driver or on-site driver as required by the system design
Clean the lens during routine maintenance to maintain light output

FAQ

Square Shape Half Mask LED Underground Light Questions

What is the cut-out size for this underground light?

The fixture requires a D34 mm hole for installation, with drainage provided below the pot.

Can it run on 12V or 24V?

Yes. The model is available for DC12V or DC24V input, so it can be used in low-voltage landscape systems.

Is the driver included?

No. The fixture is supplied without a driver, allowing integration with centralised or site-specific driver systems.

Is IP67 sufficient for areas that flood?

Yes. IP67 covers temporary immersion, which is typical for in-ground fixtures in paved areas after rain. For permanent submersion, use an underwater luminaire.

What is the warranty?

This model carries a 3 year warranty. Across the FENGDIAN range, warranty is 2 to 5 years depending on the product.

Can I order a sample before placing a full order?

Yes. Sample orders are accepted, mixed samples are acceptable, and samples typically ship within 3-5 days.

How long does mass production take?

Mass production is typically 1-2 weeks, and goods normally ship via DHL, UPS, FedEx or TNT with 3-5 days in transit, or by air or sea freight.
