How to Install a Koru Swirl Garden Light in 30 Minutes

A dark path makes a garden hard to use after sunset. If you want sculptural light that guides feet and shows off planting, the koru swirl garden light does both jobs. This guide shows how to fit it safely in about half an hour, from marking the spot to testing the glow.

What You Need Before You Start

Koru Gum designs Corten steel bollards 120mm wide in three heights: 485mm small, 695mm medium and 995mm large. Each is a 7W IP65 LED on 12V, tri-colour 3000K, 4000K or 6000K, 560 to 600 lumens and 30,000 hour rated life. The 12V transformer is not included, so choose one with at least 20 per cent headroom over total wattage.

Check Your Kit

Confirm bollard shell, LED module, base plate, fixings and outdoor connector. Inspect on arrival and report freight damage within ten business days.

Tools for the Job

Tape, marker, small shovel, spirit level, screwdriver, low voltage cable and weatherproof outdoor outlet. If you lack an exterior outlet, have a licensed electrician add one to meet AS/NZS 3000.

Pick The Right Spot

For paths, space fittings 2 to 3 metres apart so light pools overlap without glare. In beds, keep the base 300 mm clear of foliage so the Koru pattern can throw shadow on the paving. Avoid low spots where water pools, even with an IP65 rating.

Install Your Koru Swirl Garden Light In Four Steps

Step 1: Mark and Prep the Base

Mark the centre and create a firm footing. For the lawn, use the ground spike or a 200 mm deep concrete pad. Level both ways. Corten will develop its rust patina over time, so handling marks blend away.

Step 2: Run the Low-Voltage Cable

Mount the transformer above ground in a ventilated spot near the outlet. Do not bury it. Run a low-voltage cable in a shallow trench 50 mm to 75 mm deep to the fitting, leaving 400 mm slack for the joint.

Step 3: Connect And Set Colour Temperature

Switch power off at the outlet. Join the cable to the bollard lead with an outdoor-rated connector. Set colour before sealing: 3000K for warm entertaining, 4000K for clear path visibility, 6000K for crisp white near driveways.

Step 4: Fix the Bollard and Test

Secure the base plate, stand the bollard and check plumb. Restore power and test at night. Aim light to the ground, not into eyes.

Finishing Touches That Last

Backfill, tamp and cover cable. Keep mulch 20 mm clear of steel for airflow. Wipe the lens clean. Over months Corten shifts from bright orange to stable russet, a protective layer that needs no paint.

A koru swirl garden light gives daytime sculpture and nighttime guidance from one fitting. With a correctly sized transformer and tidy cable run, most installs take about 30 minutes per light. Koru Gum designs its Corten range in Australia for local conditions, with a 5-year steel warranty and a 12-month LED warranty.

FAQs

Do I Need An Electrician For A 12V Koru Swirl Light?

The low-voltage side from the transformer to the light can be done by a handy homeowner in many states, but any 240V outlet work must be done by a licensed electrician to meet Australian wiring rules.

What Transformer Size Do I Need?

Add up the total wattage of all 7W fittings on the circuit and add 20 per cent. A single fitting needs at least 12V 10W, while a run of four needs around 35W minimum.

Can I Install On Concrete Or Decking?

Yes. Use a surface-mount base with masonry anchors or deck screws. Run the cable through a conduit sweep to keep the entry neat and weather tight.

How Does Corten Steel Change Outdoors?

Fresh steel starts grey, turns bright orange within weeks, then settles to a stable russet patina over one to three years through natural wetting and drying.

What Spacing Works Best for a Path?

For residential paths, 2 to 3 metres apart gives overlapping pools at 560 to 600 lumens. Use the 995 mm height for driveways and the 485 mm height for low planting.
