Collingwood SL220 LED Spike Light - Black - Low Voltage

A spike light that vanishes into the border by day

The SL220 is a low voltage garden spike light designed to be seen only by its effect. It is a compact cylinder, 62.5mm across, sitting on a slim stem that pushes straight into soft ground. Total height is 440mm and 240mm of that goes below the surface, so very little of the fitting stands proud of the planting. What you notice after dark is the lit tree or the washed wall, not the black LED spike light doing the work.

The black finish

Black is the quiet choice across the SL220 range. Against dark bark, ivy, slate chippings or a charcoal fence panel it reads as shadow rather than hardware, which is the point when the light is meant to be the feature. The body is anodised aluminium in a fine satin black, matt enough that it will not throw a glint back when a neighbouring fitting catches it. It sits naturally alongside black outdoor wall lights, dark powder coated railings and modern grey stone, and it is a gentler presence in a loose, naturalistic planting scheme than a bright stainless steel head would be.

How It Works

This is the low voltage version, so it runs from a separate LED driver rather than straight off the mains, and the fittings on a run are wired in series. Collingwood lists driver inputs from 150mA up to 700mA. At 700mA the SL220 draws 4.6W and gives 515 lumens at 2700K, 520 lumens at 3000K or 538 lumens at 4000K. At 350mA it drops to 2.2W for a softer, lower level effect. Colour temperature and beam are chosen at the point of ordering, because each combination is a separate build: the narrow 12 degree spot for sending light up a tall trunk, the wide 40 degree flood for washing a shrub or a run of wall. Collingwood measures 200 lux at 5.3 metres on the 12 degree and at 2.4 metres on the 40 degree. The head tilts through 90 degrees once the spike is seated, so the aim can be adjusted after the ground work is done. A 3m rubberised flying lead comes attached. The LED is integrated, so there is no lamp to buy, but the driver and any waterproof connectors are separate items.

Where It Works Best

Borders and beds are the natural home. Set one into the soil a foot or so back from a multi stem birch and the narrow beam runs the trunk up into the canopy. Angle a pair at a rendered garden wall and the wide beam gives a soft, even wash rather than a hot spot. They work along a path as well, tucked into the planting rather than lined up like runway markers, and they earn their keep on a patio border where the shape of the garden should still read from indoors after dark. Because the spike simply lifts out, the scheme can move when a shrub outgrows its position or a bed gets replanted, which is far harder with anything set into concrete. Collingwood also lists the SL220 as suitable for coastal areas, so an exposed seaside garden is fair ground.

About Collingwood Lighting

Collingwood designs and manufactures its LED lighting from Sywell in Northamptonshire, and has worked in LED specifically since 2002, which is a long innings in a field that has changed as quickly as this one. The brand states it was among the first to put fire rated, fully sealed for life and mains dimmable LED products in front of the UK electrical wholesale trade. Collingwood has also been awarded an EcoVadis Gold medal, placing it in the top 5% of companies assessed worldwide for sustainability.

Good to Know

• Covered by Collingwood's 7 year warranty.
• IP65 rated. The first digit means it is fully sealed against dust, the second that it will take water jets from any direction, which covers British rain, an irrigation system and hosing the patio down.
• Class III and SELV. The fitting itself only ever sees safe extra low voltage, with the mains side handled by the driver.
• The driver is not included and needs sizing to the run. Collingwood pairs the SL220 low voltage with the DRV150700 for one to six fittings, or the DRV350700TD where dimming is wanted, taking two to six fittings at 350mA and 500mA or two to four at 700mA.
• Dimmable only when run from a dimmable driver. There is no dimming control inside the fitting.
• Series wiring, with a 3m H05RN-F rubberised flying lead of 6mm outside diameter. Any joint needs a proper waterproof connector or junction box, sold separately.
• CRI above 80 and SDCM3 colour consistency, so a run of them stays matched rather than drifting apart in tone. Rated LED life is 70,000 hours to L70.
• Maximum ambient temperature 55°C. Weight 580g.
• The GH220 glare hood and the GS220 baffle snoot are separate accessories if the source needs shielding from a window or a seating area.
• Care: wipe the lens with a damp cloth occasionally and clear leaf litter and soil splash from around the head so the beam stays clean.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Does the Collingwood SL220 low voltage spike light need a separate driver?
Yes. The SL220 low voltage LED spike light has no driver built into it and must be powered by a separate LED driver, with the fittings on a run wired in series. Collingwood lists driver inputs from 150mA to 700mA.

How bright is the SL220 low voltage spike light?
Driven at 700mA the SL220 low voltage spike light uses 4.6W and produces 515 lumens at 2700K, 520 lumens at 3000K or 538 lumens at 4000K. Run at 350mA it drops to 2.2W for a lower light level.

Can a Collingwood SL220 low voltage spike light be dimmed?
The SL220 low voltage spike light can be dimmed, but only when it is run from a dimmable LED driver such as Collingwood's DRV350700TD. The fitting has no dimming control of its own.

How far into the ground does the SL220 spike go?
The SL220 spike light is 440mm tall overall and 240mm of that sits below the surface, leaving a head of 62.5mm diameter above ground level.

What is the difference between the 12 degree and 40 degree beam on the SL220?
The 12 degree SL220 is a narrow spot that reaches 200 lux at 5.3 metres, suited to tall trees and columns, while the 40 degree version is a wide flood reaching 200 lux at 2.4 metres, better for shrubs and washing a wall.
