Collingwood SL220 LED Spike Light - Copper - Low Voltage

A Low Voltage Spike Light That Ages Into the Garden

The Collingwood SL220 is a ground spike accent light, the kind you push into a border or lawn edge to send a controlled beam of LED light up into a tree, a shrub or a section of wall. This is the low voltage version, so it runs from a separate driver rather than mains, and it's the copper bodied option in the range, the one built to look different in five years than it does on day one. This particular listing is the 2700K warm white fitting with the wide 40 degree beam.

Solid Copper, Left to Weather on Its Own Terms

The barrel, stem and spike are made in copper rather than the anodised aluminium or stainless steel finishes used elsewhere in the SL220 range. New, it has that bright, warm orange copper tone, but left outdoors it reacts with rain and air and gradually dulls to a deeper, greener patina over roughly a year or two. Most people who choose copper for garden lighting want exactly that change, it tends to suit a planted, established garden better than a fitting that stays showroom bright. It sits comfortably against gravel, bark mulch, stone paving and the layered, informal planting where a bit of ageing metal looks intentional rather than tired.

How It Works

The LED is integrated into the head rather than fitted as a replaceable lamp, and the head tilts through 90 degrees so the spike can be planted straight and the beam aimed afterwards. This copper listing runs the 700mA driver setting, drawing 4.6W and giving out roughly 515 lumens in 2700K, a step up from the 2.2W, 290 lumen output the same fitting gives at the lower 350mA setting. It's a Class III low voltage product, so a separate driver is needed, it isn't built into the fitting, and SL220 units wire in series, so the combined wattage of every spike light on one driver has to stay within what that driver can supply. Overall it stands 440mm tall with a 62.5mm diameter head, and roughly 240mm of that length is the spike itself, driven into the ground. A 3m flying lead runs from the base back to the driver circuit. Collingwood's own JB5 gel filled connector, GH220 glare hood and GS220 snoot are separate accessories that pair with it if you need a weatherproof joint or tighter control over spill light.

Where It Works Best

This is a light for the parts of the garden worth noticing after dark: a specimen tree or multi stemmed shrub lit from below, a run of border planting, the base of a wall or chimney breast, steps, or the edge of a gravel driveway. The wide 40 degree beam on this listing suits washing a broader area of planting or a wall face rather than picking out one narrow point, which the 12 degree version elsewhere in the range is built for. Being low voltage and Class III, it's also a sensible choice near patios and seating areas where people or pets might brush past the fitting.

About Collingwood Lighting

Collingwood designs and manufactures its LED products from Sywell in Northamptonshire, and has worked specifically in LED technology since 2002. The brand says it was among the first to bring fire rated, fully sealed for life and mains dimmable LED products into the UK's electrical wholesale market, at a point when much of the trade hadn't caught up with LED yet. Collingwood also holds an EcoVadis Gold medal, which places it in the top 5% of companies assessed globally for sustainability.

Good to Know

• Backed by a 7 year manufacturer warranty.
• IP65 rated, sealed against dust and protected against low pressure water jets from any direction, so it's built to stay outdoors through the seasons.
• Class III, SELV low voltage, run from a separate driver rather than wired straight to mains at the fitting.
• Dimmable, but only when paired with a suitable low voltage dimmable driver, a standard non dimmable driver won't allow it.
• Wired in series, so total the wattage of every spike light going on one driver before sizing it.
• CRI of 80 and an LED rated for roughly 70,000 hours to L70.
• The copper casing will weather to a darker, greener tone outdoors. That's a natural reaction to the material, not a fault.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Does this copper SL220 spike light need a separate driver?
Yes, it's a Class III low voltage fitting, so it needs a separate low voltage driver sized to the number of spike lights being run, and that driver isn't built into the light or included with it.

How bright is this copper SL220 at 2700K?
Run at the higher 700mA setting it draws 4.6W and gives roughly 515 lumens, while the lower 350mA setting draws 2.2W for around 290 lumens, both through the same wide 40 degree beam on this listing.

How much of the SL220 sits below ground once it's installed?
The SL220 is 440mm long overall, and around 240mm of that is the spike section, so roughly half the fitting disappears into the soil once it's pushed fully home.

Will the copper finish on this spike light stay bright?
No, being solid copper it will gradually darken and pick up a greenish patina with outdoor exposure, typically over about a year or two, which is normal weathering rather than a defect.

Are the JB5 connector, GH220 glare hood or GS220 snoot included with this light?
No, those are separate accessories within the Collingwood range and need to be ordered on their own if a weatherproof joint or extra glare control is needed.
