Collingwood SL220 LED Spike Light - Black - Straight to Mains

A mains voltage garden spike light with the driver already inside

The SL220 is a small, serious LED spike light made for uplighting in the garden. This is the straight to mains version, which means the driver sits inside the fitting itself. There is no separate transformer to buy, no low voltage run to plan and nothing extra to find a dry home for. You bring a 230V supply to it, push the spike into the ground and point the head at whatever you want lit. It draws 5.7W and gives roughly 515 to 530 lumens depending on the colour temperature you order, which is plenty for a tree or a stretch of wall.

Black anodised aluminium

Black is the quietest of the SL220 finishes. The anodising leaves a flat, slightly satin surface rather than a glossy one, so the body does not catch the light or draw the eye during the day. Set into a planted border or tucked behind low shrubs, a black spike light effectively disappears, and what you notice after dark is the lit trunk or the lit wall rather than the thing doing the lighting. It sits naturally alongside dark stained garden joinery, charcoal paving, black painted railings and slate. Where the brushed metal and copper versions of this fitting are meant to be seen and to weather visibly over time, black is the one you choose when you want the light and not the light fitting.

How It Works

It arrives as one piece. Head, stem and ground spike come assembled with a 3m flying lead already fitted, so the electrical work is simply a matter of getting a supply out to that lead and terminating it in a suitable weatherproof enclosure. The whole thing stands 440mm tall, roughly 240mm of which is the spike that goes into the soil, and the head measures 62.5mm across. Once the spike is bedded in, the head tilts through 90 degrees, from pointing straight up to fully horizontal, so you can aim at a trunk, a canopy or a wall face without disturbing the ground again. The body is anodised aluminium and the whole fitting weighs 0.7kg.

Two decisions are made at the point of ordering. The first is the beam. A narrow 12 degree beam throws a tight column of light and suits tall, slim subjects such as a single trunk, a column or a piece of sculpture. A wide 40 degree beam spreads much further and is the better choice for a broad shrub, a hedge, a multi stemmed tree or a run of wall. The second is colour temperature. 2700K is a soft, candle leaning warmth, 3000K is a standard warm white, and 4000K is crisper and more neutral, which tends to make green foliage read as green rather than olive. The LED is integrated, so there is no lamp to change later, and colour rendering is quoted at CRI 80.

Where It Works Best

Uplighting mature planting is the obvious job. Sit one at the base of a birch or an olive and the narrow beam will run light up the trunk and into the branches, which is the effect most people are actually after when they search for a garden spike light. Grouped along a border, three or four of them turn a flat, dark bed into something with depth. The wide beam is better suited to washing a boundary wall, a fence panel, a run of hedging or a garden building, and it is the more forgiving option if the fitting will sit close to whatever it is lighting.

Because it is straight to mains, it is a sensible choice on larger gardens and longer cable runs where a low voltage system would start to need careful voltage drop calculations, and on jobs where a mains circuit is already being run out to the garden for sockets or a garden room. It also works well on driveways and around parking areas, lighting specimen planting or gate piers. It is designed for outdoor use only.

About Collingwood Lighting

Collingwood designs and manufactures its LED products in Sywell, Northamptonshire, and has worked exclusively in LED since 2002, which is a long time in a category that only really matured in the last decade. 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 has also been awarded an EcoVadis Gold medal, which places it in the top 5% of companies assessed worldwide for sustainability. The 7 year warranty on this fitting is a fair indication of how the company expects its exterior products to hold up.

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 it will cope with British rain, hosing down and garden irrigation.
• Class I, so the installation requires an earth connection.
• Not dimmable. If you want the ability to dim your garden lighting, this is not the fitting for it.
• Wired in parallel, so each fitting connects across the same supply rather than in a chain.
• Supplied with a 3m flying lead. Any joint out in the garden needs a properly rated weatherproof enclosure.
• The head tilts through 90 degrees and can be reaimed at any time without lifting the spike.
• GH220 glare hoods and GS220 snoots are made for this fitting and are available separately if a beam needs shielding from a window or a seating area.
• Care is straightforward. Wipe the lens clear of soil splash and leaf debris occasionally, and keep planting from growing across the beam.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Does the Collingwood SL220 mains spike light need a separate driver or transformer?
No. The straight to mains version of the Collingwood SL220 has the driver built into the fitting and connects directly to a 230V mains supply, so no external driver or transformer is needed.

How tall is the Collingwood SL220 spike light and how far does the spike go into the ground?
The Collingwood SL220 spike light is 440mm tall overall with a head diameter of 62.5mm, and approximately 240mm of that length is the spike that pushes into the soil.

Should I choose the 12 degree or the 40 degree beam angle?
The 12 degree narrow beam of the Collingwood SL220 concentrates light into a tight column for uplighting single tree trunks, columns and sculpture, while the 40 degree wide beam spreads light across broader subjects such as hedges, large shrubs and wall faces.

Can the Collingwood SL220 mains spike light be dimmed?
No. The mains version of the Collingwood SL220 spike light is not dimmable and should be switched on and off rather than run through a dimmer.

What is the difference between 2700K, 3000K and 4000K on this spike light?
On the Collingwood SL220, 2700K produces a soft warm glow closest to candlelight, 3000K is a standard warm white, and 4000K is a cooler and more neutral white that makes green foliage appear truer in colour.
