Facade Lighting Project

24*2W Adjustable Beam Angle LED Underground Light

The FD-U260R48 is a 48W recessed in-ground LED luminaire designed for architectural and landscape lighting projects requiring on-site beam angle adjustment. The fixture features a stainless steel 304 cover and an aluminium body, with an IP67 rating suitable for installation in paved areas exposed to standing water. It operates on AC85-265V input and includes a driver, allowing integration into standard mains-fed systems. The optic assembly is adjustable within the housing, enabling precise aiming after the pot is cast.

Benefits

Key Benefits

  • Beam angle can be adjusted after the pot is cast, eliminating the need for re-coring if the aiming changes
  • One fixture type supports grazing, uplighting, and tree washing in the same project
  • IP67 rating ensures reliable performance in recessed positions that flood during rain
  • Stainless steel 304 cover resists corrosion and wear from foot traffic and cleaning
  • AC85-265V input supports direct connection to standard building mains
  • Driver is included, simplifying installation and reducing on-site wiring complexity
Where It Is Used

Application Scenarios

  • Grazing textured walls or stone facades from a paved plaza at the building line
  • Uplighting columns, pillars, or architectural features in hotel and commercial entrances
  • Tree and palm uplighting in public parks, residential courtyards, and streetscapes
  • Marking pedestrian pathways and edge lines in mixed-use developments with paved surfaces
Buyers

Who It Is For

  • Facade and landscape lighting contractors installing in-ground fixtures in hardscape
  • Lighting designers needing on-site aiming flexibility after civil works are complete
  • Electrical wholesalers supplying architectural lighting projects in the Middle East and Europe
  • Brand owners sourcing OEM in-ground luminaires under their own label
Why It Matters

Problems It Solves

  • Fixed-optic in-ground lights require final aiming decisions before the pot is cast, risking rework if details change
  • Non-adjustable fixtures often require re-coring when facade or landscape plans are revised late in the project
  • Aluminium or painted trims degrade in wet, salted, or frequently cleaned paving areas
  • Projects using both mains and low-voltage systems would otherwise need multiple fixture types
Engineering

Technical Features

  • Adjustable optic assembly inside the housing for on-site beam aiming
  • Stainless steel 304 cover over an aluminium body for corrosion resistance and heat dissipation
  • IP67 sealing for recessed positions subject to temporary immersion from rainwater
  • OSRAM LED chip for consistent light output and long life
  • AC85-265V input voltage range for compatibility with standard building mains
  • Driver included with the fixture, reducing on-site component count
Materials

Materials

  • Stainless steel 304 cover for the exposed surface, resistant to corrosion and abrasion
  • Aluminium body for efficient heat transfer into the surrounding backfill
  • Tempered glass lens over the optic for impact resistance and light transmission

Comparison

Compared With the Alternatives

Fixed-optic in-ground light

Higher initial cost, but avoids re-coring when aiming changes after the pot is cast

Surface-mounted spike light

No civil work required, but the fixture is exposed and vulnerable to damage or vandalism

Aluminium-trim in-ground light

Lighter and less expensive, but the trim is more prone to corrosion in wet or frequently washed paving

Installation

Use Guide

  • Cast or core a D236 mm hole and provide drainage below the fixture before backfilling
  • Adjust the beam angle with the fixture powered to verify the light direction against the target
  • Ensure the cover is flush with the finished paving level to avoid trip hazards
  • For long runs, size the cable to account for voltage drop across the circuit
  • Clean the glass lens during routine paving maintenance to maintain light output
FAQ

24*2W Adjustable Beam Angle LED Underground Light Questions

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

The fixture requires a D236 mm hole, with drainage provided below the pot.

Can the beam angle be adjusted after installation?

Yes. The optic assembly is adjustable inside the housing, allowing on-site aiming after the pot is cast.

Is the driver included?

Yes. The driver is included with the fixture, simplifying installation.

Is IP67 sufficient for areas that flood after rain?

Yes. IP67 covers temporary immersion, which matches the condition of recessed fixtures in paved areas during rain.

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 typically takes 1-2 weeks, and goods are shipped via DHL, UPS, FedEx, or TNT with 3-5 days in transit, or by air or sea freight.
