A 700mA driver that dims from an ordinary wall dimmer
The Collingwood PSMD700610 is a constant current LED driver that holds a steady 700mA output and takes its dimming instruction straight from the mains supply. That is the part worth pausing on. Most constant current drivers want a separate control signal such as 1 to 10V or DALI, which means running extra cable and adding extra kit. This one answers to a standard dimmer switch on the lighting circuit instead, so a simple job stays simple.
Collingwood rates the output at 12W to 24W across an output voltage window of 17V to 34V. Because the current is fixed at 700mA, that voltage window is what decides how much you can hang off it, and it sets a lower limit as well as an upper one. The brand's own guidance is 6 to 10 of its 1W products, or 2 to 3 of its 3W products, on a single driver.
The unit itself
It is a slim moulded plastic case in white, 155mm long, 35mm wide and just 22mm tall, with pale turquoise end caps at either side. The full specification is printed along the top face, so the model code, the input and the output stay readable once the driver is tucked into a ceiling void where nobody wants to be hunting for a spec sheet.
The end caps come off to reach the screw terminals, which take cable from 0.5mm² up to 1.5mm² on both the input and the output side. That 22mm height is the number that earns its keep. It slides into shallow voids and behind bulkheads where a chunkier brick shaped driver simply will not go.
How It Works
Mains at 220V to 240V AC, 50Hz, arrives at the input terminals. The driver converts it into a regulated 700mA DC output and feeds that to the fittings, which sit in series on a constant current circuit. When the dimmer on the lighting circuit chops the mains waveform, the driver reads the change and reduces the current it delivers, so every fitting on the output dims together and stays in step.
The printed label states that it works with trailing edge or leading edge dimmers, which gives you room to move if the dimmer already on the wall is not the type you would have chosen. It is supplied as the driver on its own. No dimmer, no fittings and no mounting bracket are included.
Where It Works Best
This is a dry location component, so it belongs somewhere sheltered and ventilated. A ceiling void, a loft, an airing cupboard, a service riser, the back of a joinery unit, or a plant cupboard feeding a run of fittings further along. It should never be buried in loft insulation and it should never sit outdoors or anywhere it might catch water or condensation.
The typical job is a small group of 700mA Collingwood fittings that the client wants on a dimmer without a control system sitting behind it. Ground lights along a path fed from a driver inside the garage. A short run of step lights driven from a hallway cupboard. A cluster of accent downlights on one dimmed circuit. The fittings themselves can be outdoor rated. This driver cannot, so it stays indoors and the low voltage wiring runs out to them.
About Collingwood Lighting
Collingwood designs and manufactures its LED products in Sywell, Northamptonshire, and has been working in LED technology since 2002. The brand states it was among the first to put fire rated, sealed for life and mains dimmable LED products in front of the UK electrical wholesale trade, and a driver like this one sits squarely in that mains dimmable thread. Collingwood also holds an EcoVadis Gold medal, which puts it in the top 5% of companies assessed for sustainability worldwide.
Good to Know
- Backed by a 5 year warranty.
- IP20 rated. That means the case keeps out fingers and solid objects above 12mm but offers no protection against water at all, so it must go in a dry indoor position.
- Class II double insulated construction with a SELV output, so no earth connection is needed at the driver.
- Input is 220V to 240V AC at 50Hz. Output is a fixed 700mA at 17V to 34V DC, which works out as 12W to 24W of connected load.
- Built in protection against short circuit, overload and overcurrent.
- Rated for an ambient temperature up to 45°C with a maximum case temperature of 80°C. Give it air and keep it away from insulation.
- Power factor of 0.95 and efficiency of around 80%.
- Dimming caveat. Because the dimming happens on the mains side, the pairing matters. Use a trailing edge or leading edge dimmer that is rated for LED loads, and check the dimmer's own minimum load figure against what you are actually connecting. A dimmer sized for old filament lamps will often flicker or drop out on a 24W LED circuit.
- Screw terminals accept 0.5mm² to 1.5mm² cable on both input and output.
- Care amounts to keeping it dry, dust free and ventilated. There are no serviceable parts inside the case.
- Moonlight Design recommends installation by a registered NICEIC electrician.
Questions People Ask
What is the Collingwood PSMD700610?
The Collingwood PSMD700610 is a 24W constant current LED driver with a fixed 700mA output and an IP20 rating, designed to power 700mA LED fittings and dim them from a standard mains wall dimmer rather than a separate control signal.
Can the Collingwood PSMD700610 be dimmed with a normal wall dimmer?
Yes. The PSMD700610 is a mains dimmable driver and its printed label confirms it works with trailing edge or leading edge dimmers, so no separate 1 to 10V or DALI control cable is required.
How many fittings will the Collingwood PSMD700610 run?
Collingwood states the PSMD700610 will run 6 to 10 of its 1W LED products or 2 to 3 of its 3W products, with the real limit being the driver's 12W to 24W output band at a fixed 700mA.
Can the Collingwood PSMD700610 be installed outdoors?
No. The PSMD700610 is rated IP20, which gives it no protection against water, so it must be mounted in a dry indoor position such as a ceiling void or a cupboard, even when the fittings it powers are installed outside.
What is the difference between the PSMD700610 and a constant voltage LED driver?
The PSMD700610 is a constant current driver, so it holds its output at a fixed 700mA and lets the voltage float between 17V and 34V to suit the load, while a constant voltage driver holds a fixed voltage such as 24V and lets the current vary. Fittings on a constant current driver are wired in series, not in parallel.
