Collingwood SL230 LED Twin Pole Spike Light - Black - Straight to Mains

Two Beams, One Ground Fixing

The Collingwood SL230 does something most garden spike lights cannot. It carries two independently aimed LED heads on a single slim pole, fed by one cable and held by one spike in the ground. That means one trench, one connection and two pools of light. If you have ever laid a run of separate spike lights along a path and found yourself digging twice as much as you expected, this is the fitting that solves it. This is the mains voltage version, so it wires straight to a 230V supply with no transformer in the chain.

Black Anodised Aluminium

The pole and both heads are finished in a deep, even black anodised aluminium. Anodising bonds the colour into the surface of the metal rather than sitting on top of it as a paint layer would, which is why Collingwood rates the finish for coastal use. In daylight the black reads as a quiet vertical line rather than an object, which is exactly what you want from garden lighting that is meant to be noticed only after dark. It disappears against hedging, dark fencing, yew, box and slate, and it sits comfortably in contemporary schemes where stainless steel would look too bright. The barrel heads are 62.5mm across, small enough to stay discreet at the top of the pole.

How It Works

Each head tilts through 90 degrees and rotates through 330 degrees, and the two move completely independently of each other. One can graze up the trunk of a tree while the other washes down across the path beside it. Both throw a 40 degree beam, which is broad enough to cover planting and paving without spilling everywhere. Total load is 11.4W for the pair, giving around 1030 lumens at 2700K, 1040 lumens at 3000K and slightly more at 4000K, at a CRI of 80. The LEDs are integrated and sealed in, so there are no lamps to change, and Collingwood quotes an L70 B10 life of 70,000 hours.

Wiring is parallel and the driver is built in, which is what the Straight to Mains name refers to. The fitting is supplied pre wired with a watertight cable tail ready to join into your 230V garden circuit, typically through a waterproof junction box such as Collingwood's JB5. Overall height is 845mm with the spike included, so the heads sit at roughly knee to thigh level once pushed into soft ground. Choose your colour temperature at the point of order, since the LEDs are fixed at 2700K, 3000K or 4000K depending on the variant you pick.

Where It Works Best

This is a path and driveway light first. Space a few down one edge of a gravel drive and you light the surface and the planting behind it from the same posts. On a stepped garden it works particularly well, with one head dropped onto the treads and the other lifted into whatever sits alongside them. It is also a neat answer for a specimen tree or a large shrub, where the two heads can be crossed to light the form from slightly different angles rather than flattening it with a single beam. Borders, mature hedging, pergola uprights and the edges of a lawn all suit it. Because the spike simply pushes into the ground, you can move a fitting a metre or two once the planting fills out and the effect changes.

About Collingwood Lighting

Collingwood designs and manufactures its LED products in Sywell, Northamptonshire, and has worked in LED technology alone since 2002. The brand states it was among the first to bring fire rated, fully sealed for life and mains dimmable LED products to the UK electrical wholesale market. It also holds an EcoVadis Gold medal, which places it in the top 5% of all companies assessed worldwide for sustainability. For exterior fittings like this one that background matters, because the sealing and the thermal design are what decide whether a garden light is still working in ten winters.

Good to Know

• Backed by a 7 year warranty.
• IP65 rated, meaning it is fully protected against dust and against water jets from any direction, so driving rain, garden hoses and sprinkler overspray are all fine.
• Class I, so the fitting requires an earth connection.
• Mains voltage with an integral driver. No separate transformer or remote driver is needed.
• Collingwood does not list a dimmable option for the mains SL230, so plan it onto a standard switched circuit rather than a dimmer.
• Colour temperature is fixed by the variant you order and cannot be changed later, as the LEDs are integrated.
• GH220 hoods and GS220 snoots are offered by Collingwood to cut glare where the heads are aimed towards a seating area or a window. They are separate items.
• Weighs 2 kg, and the spike needs reasonably firm soil to stay upright and square.
• Wipe the lenses with a soft damp cloth now and then. Leaf litter and hard water spotting dull the output faster than anything else outdoors.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Does the Collingwood SL230 mains twin pole spike light need a transformer?
No. The Straight to Mains version of the Collingwood SL230 has an integral driver and connects directly to a 230V supply, so no separate transformer or remote LED driver is required.

Can the two heads on the SL230 be aimed in different directions?
Yes. Each of the two heads on the Collingwood SL230 tilts through 90 degrees and rotates through 330 degrees on its own, so one head can light a path while the other is aimed up into a tree or a wall.

How tall is the Collingwood SL230 twin pole spike light?
The Collingwood SL230 measures 845mm in overall height including the ground spike, with each cylindrical head measuring 62.5mm in diameter.

Is the SL230 spike light suitable for a coastal garden?
The Collingwood SL230 in black is made from anodised aluminium and is rated IP65, and Collingwood describes the finish as coastal protected, which makes it suitable for salt exposed locations near the sea.

What is the difference between the 2700K, 3000K and 4000K versions of the SL230?
The three versions of the Collingwood SL230 differ only in the colour of the light. 2700K is a soft amber white that flatters brickwork and warm stone, 3000K is a slightly cleaner warm white that suits most gardens, and 4000K is a crisp neutral white that reads brighter against green foliage and grey paving.
