iLight In-ground luminaires are designed for projects where the light must disappear into the architecture while still delivering strong performance. They sit flush with the surface, withstand weather and loads, and provide precise beams for façades, trees, pathways and plazas. This makes them a common choice for hotels, public squares, retail exteriors, and premium residential landscapes. On exterior projects, planners usually mix several in-ground ranges to balance design and budget. Compact residential paths and gardens are often lit with nordlux in ground luminaires, while hotel approaches, plazas and façade lines rely on higher-spec leds c4 in ground luminaires. Cost-driven housing estates and simple access routes are frequently standardised on ledmaxx in ground luminaires and everyday kanlux in ground luminaires, with decorative villa, restaurant and boutique hotel entrances often finished using ideal lux in ground luminaires to match façade and terrace lighting.

Below is a practical breakdown of how to think about this category when you’re selecting, specifying or purchasing.

Where iLight In-ground luminaires are used

In-ground fixtures are primarily about discreet integration and controlled accent light. Typical applications include:

Façade grazing – narrow-beam iLight In-ground luminaires placed near walls to create vertical light and texture.
Tree and landscape highlighting – wide- or medium-beam units set in soft or hard landscape to pick out trees, shrubs, sculptures.
Path and plaza safety – symmetric distributions to provide low-level orientation on walkways, plazas, driveways.
Entrance and branding zones – in-ground uplights under canopy edges, signage, flags and columns to create a premium first impression.
Pool and water-adjacent areas – models with elevated corrosion resistance and sealing, for humid or splash-prone locations.

Because the body is buried, the visible design is mostly the trim ring and glass – so the emphasis is on performance, durability and visual comfort, not decorative shape.

Product assortment of iLight In-ground luminaires

Within the iLight In-ground luminaires range, you will typically encounter several sub-families and options:

Round and square formats
- Small diameters for subtle accents or tight grid layouts.
- Larger formats for high-output façade and tree lighting.
Fixed vs adjustable
- Fixed optics for simple vertical uplighting when the target is directly above or very close to the fitting.
- Adjustable or tiltable versions (often with internal aiming mechanisms) when you need to hit an offset object such as a tree crown or high architectural detail.
Optic variants
- Very narrow spots (e.g. 8–10°) to draw sharp attention and minimise spill.
- Medium and wide beams for more general wash.
- Asymmetric wall-wash or grazing optics to spread light evenly along façades.
Load-rated series
- Walk-over luminaires for pedestrian zones, terraces and decks.
- Drive-over luminaires with higher mechanical resistance and reinforced bodies for car parks, access roads and plazas.
Control and driver options
- On/off versions for simple, cost-sensitive projects.
- Dimmable (DALI, 0–10 V, or phase-cut) for dynamic scenes and energy control.
- RGB or RGBW variants in certain ranges, for colour-changing façade and landscape concepts.

When you evaluate the assortment, it’s helpful to group them by mechanical rating, optics, and control interface rather than just by size.

Construction and materials: what’s inside iLight In-ground luminaires

Because in-ground fixtures live in harsh conditions (water, dirt, mechanical load, thermal stress), the material choices are critical:

Housing
- Typically cast or extruded aluminium with heavy powder coating, sometimes marine-grade alloys for high-corrosion environments.
- The body is often separate from the installation sleeve or mounting box, which stays in the ground while the luminaire can be removed for service.
Front ring / trim
- Stainless steel (often 316) for maximum corrosion resistance and a clean architectural finish.
- Sometimes anodised aluminium trims for more colour options and lighter weight.
Glass
- Thick, toughened safety glass, often with an anti-slip surface for walk-over versions.
- High-impact ratings (IK) to handle footsteps, trolleys, sometimes vehicle tyres.
Sealing system
- Multi-stage gaskets, O-rings and compression seals around the glass and cable entries.
- High ingress protection (commonly IP67 / IP68) to resist temporary immersion and long-term moisture.
Thermal management
- LED boards mounted to thermally conductive cores and housing surfaces.
- The in-ground situation is thermally challenging, so proper heat paths and driver design are essential for lifetime.

When comparing iLight In-ground luminaires with cheaper generic uplights, this is where you see the difference: better material quality, sealing detail and thermal design translate directly into fewer failures and more stable colour over time.

Light quality and optics in iLight In-ground luminaires

Performance is not just about lumen output; it’s about how the light is used:

Beam control – High-quality reflectors or TIR lenses give tight distributions with minimal spill and good cut-off. This is key for façade and tree lighting, where wasted light quickly becomes glare or light pollution.
Colour temperature – Warm white (2700–3000 K) is typically chosen for hospitality and residential applications to keep façades and greenery looking inviting. Neutral white (3500–4000 K) can emphasise modern architecture or commercial exteriors.
Colour rendering (CRI) – Higher CRI (often 80+ or 90+) helps materials, stone, wood and foliage look natural and premium, especially in retail and hotel settings.
Glare control – Recessed light sources, internal louvers, and honeycomb or spread lenses are commonly used to soften the beam and avoid harsh points of brightness when people look down at the luminaire.

For a real project, you’d align beam angles, lumen packages and colour temperature across the iLight In-ground luminaires family so the scene is cohesive, not a patchwork of mismatched whites and intensities.

Installation and maintenance aspects of iLight In-ground luminaires

Correct installation is as important as the product itself. Key points to consider:

Mounting sleeves and drainage
- Most iLight In-ground luminaires use a dedicated sleeve set in concrete or compacted substrate.
- Good practice is to provide drainage under or around the housing so water does not sit against the fitting long-term.
Cable routing and connections
- Pre-wired cables with factory-fitted glands and external IP-rated junction boxes are common to avoid open connections inside the soil.
- Always check if connectors are included or if you must specify them separately.
Access for servicing
- Many units allow access to the LED module and driver from the top after removing the trim and glass.
- For some models, the driver may be remote, kept in a nearby service box to reduce heat and simplify replacement.
Surface integration
- Ensure that the top of the iLight In-ground luminaires sits flush with the finished surface (paving, decking, resin-bound gravel) to avoid trip hazards.
- Take into account settlement of soil and finishes so the fitting doesn’t end up proud or recessed over time.

Procurement should always align with installers about sleeves, concrete works, drainage layers and cable routes before ordering large quantities.

Performance, ratings and compliance

From a technical and safety standpoint, these are the parameters you should verify when choosing iLight In-ground luminaires:

Ingress protection (IP) – Typically IP67 or higher for ground installations; this indicates resistance to dust and temporary immersion.
Mechanical impact (IK) – High IK ratings for walk-over and drive-over versions to withstand impacts and loads.
Load rating – Clear indication whether the luminaire is suitable for pedestrian-only, light vehicle, or heavy vehicle areas.
Operating temperature – Ensure the declared ambient range matches your climate, especially in regions with frost or extreme heat.
Electrical safety and standards – Compliance with relevant luminaire standards and tested drivers (overload, thermal, short-circuit protection).

Checking these values in advance avoids expensive rework when a project’s safety consultant or local authority requests documentation.

How to choose the right iLight In-ground luminaires for your project

When selecting within the iLight In-ground luminaires portfolio, it helps to follow a simple decision logic:

Define the lighting role
- Accent (tree, column, statue), wall wash, general pathway light, or purely decorative effect.
Set photometric requirements
- Decide the target illuminance and distances; from that, choose lumen package and beam angle.
- Run or request basic calculations to confirm spacing and aiming.
Match the environment
- Pedestrian vs vehicle load, presence of de-icing salts, proximity to water, probability of vandalism.
Select colour and control
- Pick colour temperature and CRI to support the architectural concept.
- Decide whether you need dimming, dynamic scenes, or colour-changing control, and choose appropriate driver interface.
Confirm installation details
- Sleeve type, drainage concept, cable type and connection method.
- Make sure accessories (sleeves, anti-glare grids, lenses) are included in the order.
Standardise for procurement
- Use consistent product codes across similar zones.
- Avoid mixing different in-ground families without a clear design reason; consistency simplifies maintenance and reordering.
