Inground Lights: Complete Buying & Installation Guide
Inground lights are one of the most effective ways to add drama, safety and street appeal to an outdoor space. Recessed flush into driveways, paths, decks and garden beds, they wash light upwards across walls, trees and facades without a visible fixture cluttering the view. But because they sit in the ground, exposed to water, heat and often the full weight of a car, choosing the right fitting matters more than with almost any other outdoor light. This guide walks you through everything you need to know before you buy or install.
What are inground lights and where are they used?
Inground lights (also written as in-ground lights) are fixtures recessed into a surface so the lens sits flush or near-flush with the ground. Most are used as uplights, throwing a beam vertically to graze a surface and create texture and shadow. Because the fixture itself is hidden, the effect is all about the light, not the hardware.
Common applications include:
- Driveways — marking edges, adding rhythm and lifting the approach to a home.
- Paths and steps — guiding foot traffic and improving safety after dark.
- Trees and planting — uplighting trunks and canopies for a natural, layered look.
- Facades and feature walls — grazing render, stone or timber to emphasise texture.
- Water features and pools — highlighting movement and reflection (always confirm the fixture is rated for the specific wet or submerged location).
Drive-over load rating: the first thing to check
If a light will sit anywhere a vehicle can pass — a driveway, a crossover, a shared path — it must be a drive-over rated fixture. Standard garden inground lights are built for foot traffic only and will crack or fail under a car. Drive-over models use reinforced housings and thicker, load-bearing lenses designed to take the weight of a wheel.
Manufacturers publish a load rating for these fittings, so match the fixture to the traffic it will actually see. When in doubt for a driveway, always specify a drive-over rated light rather than a decorative garden version.
IP67, IP68 and proper sealing
Ingress Protection (IP) ratings tell you how well a fixture resists dust and water. For inground lights the water figure is critical because these fittings sit in the one place water collects.
- IP67 — protected against temporary immersion in water.
- IP68 — protected against continuous immersion, suitable for the wettest locations and submerged use where specified.
Look for an IP67 rating as a sensible minimum for inground use, and IP68 where the fixture may sit in standing water or near a water feature. Sealing quality also depends on correct installation — cable glands must be done up properly and any supplied gaskets seated cleanly so the rating is preserved in the field.
12V vs 240V and the role of the driver
Inground lights come in two main electrical families:
- 12V low-voltage systems run from a transformer or LED driver that steps mains down to a safer voltage. They are popular for garden and landscape work and can often be installed with more flexibility, though a licensed electrician should still handle the mains connection to the driver.
- 240V mains-voltage fixtures connect directly to the mains supply and must be installed by a licensed electrician.
Either way, the driver matters. A quality LED driver delivers stable current, reduces flicker and protects the lifespan of the fitting. For low-voltage runs, factor in voltage drop over long cable lengths so lights at the far end of a run are not noticeably dimmer.
Beam angle and spacing
Beam angle shapes the effect. A narrow beam concentrates light into a tight column — ideal for uplighting a tree trunk or a tall facade. A wider beam spreads a softer wash across a broad wall or a low planting bed.
Spacing works hand in hand with beam angle and mounting position. Set fixtures too far apart and you get isolated pools of light with dark gaps; too close and the effect looks busy and over-lit. As a general approach, plan the spacing around the surface you are lighting and the beam spread of the fitting, and mock up a couple of positions at night before committing to the final layout.
316 stainless steel for coastal sites
Salt air is punishing on outdoor hardware. If the property is near the coast — and much of Sydney is — specify fixtures with marine-grade 316 stainless steel components. The 316 grade offers markedly better corrosion resistance than 304 or plated finishes, which can pit and stain within a season or two in a salt-laden environment. For any coastal or estuarine installation, 316 is the finish worth paying for.
Heat and installation: sleeves, drainage and a licensed electrician
Inground fixtures generate heat and sit in an enclosed cavity, so installation detail directly affects lifespan and safety.
- Use the correct sleeve or housing — many inground lights are installed into a mounting sleeve set into the concrete or paving, which protects the fixture and allows it to be serviced later.
- Provide drainage — even IP-rated fittings last longer when water can drain away rather than pool around the housing. A bed of gravel beneath the fixture helps water disperse.
- Manage heat — don't smother a fitting or install it against materials that trap heat; follow the manufacturer's guidance on the surrounding build-up.
- Use a licensed electrician — mains connections must be carried out by a licensed electrician in Australia, and professional installation protects both your safety and any warranty.
Controlling glare
Because inground lights point upward, they can shine straight into the eyes of anyone walking toward them. Good fixtures manage this with recessed lenses, cowls, louvres or honeycomb baffles that cut the direct sightline to the LED. When positioning uplights near paths, seating or windows, aim to graze the surface you want to light while keeping the source itself shielded from view. The goal is to see the effect, not the glare.
Quick buying checklist
- Is the fixture drive-over rated if a vehicle can reach it?
- Does the IP rating suit the location — IP67 minimum, IP68 for the wettest spots?
- Is it 12V or 240V, and is the driver suitable for the run length?
- Is the beam angle right for the surface, and have you planned spacing?
- For coastal sites, is it 316 stainless steel?
- Do you have the correct sleeve, drainage and glare control sorted?
- Is a licensed electrician booked for the mains work?
Frequently asked questions
Can I drive a car over inground lights?
Only if the fixture is specifically drive-over rated. Standard garden inground lights are designed for pedestrian areas and will be damaged by vehicle weight, so choose a drive-over model for any driveway or crossover.
What IP rating do inground lights need?
Aim for IP67 as a minimum because these fittings sit where water collects. Choose IP68 where the light may sit in standing water or near a water feature. Correct installation is essential to preserve the rating in practice.
Do I need an electrician to install inground lights?
Any connection to the 240V mains must be done by a licensed electrician. Even with 12V low-voltage systems, having the mains-side connection and overall installation handled professionally protects your safety and your warranty.
What's the difference between 12V and 240V inground lights?
12V fixtures run from a transformer or driver that steps the mains down to a safer low voltage and are common in landscape lighting. 240V fixtures connect directly to mains. Both need professional mains connection; the right choice depends on your layout, cable runs and preference.
