25W 12V or 24V indoor LED driver

This is a small LED driver – the power supply that sits between mains and low-voltage lighting. At this size it is the unit behind a handful of step lights, a single garden spike, a short run of strip under a cabinet, or one fitting that arrived without a supply of its own. It takes mains power and converts it down to 12V or 24V DC.

It is rated to carry up to 25W of LED load. That figure is a ceiling, not a target – which matters more than it sounds.

Small drivers are the ones most often left out of a plan. A single fitting is easy to think of as self-contained, and the discovery that it needs a supply usually happens with the fitting already in hand.

Working out what size you need

Add up the wattage of the fittings this will power and keep the total comfortably under its rating. On a small driver that margin disappears quickly – two or three fittings can reach the limit, and a driver run at its ceiling gets hot and fails early.

It is often worth stepping up a size rather than matching exactly. The price difference between small drivers is slight, and the larger one leaves room to add a fitting later without pulling the supply out again.

This driver is made in both output voltages, and they are not interchangeable. Check which one your fittings need before ordering – the two look identical on the shelf and behave very differently on the run.

Where it can be installed

A small indoor driver hides easily – inside joinery, above a cabinet, or in a ceiling void. The temptation is to seal it in where it will never be seen, which is also where it will never be reached.

For anything outdoors, in a bathroom zone, or in a spot that could see condensation, use a weatherproof driver instead. An indoor driver installed outside is a failure waiting to happen, and again, not a warranty claim.

Dimming

This driver is dimmable via TRIAC (leading edge).

Dimming a low-voltage LED system happens at the driver, not at the fitting, so the driver and the dimmer or control system have to speak the same protocol. Confirm that before ordering – a mismatch usually shows up as flicker, a stunted dimming range, or the lights simply not responding.

Installation

This is a Class II driver – double insulated, so no earth connection is required at the driver itself.

The mains side is licensed electrical work and needs an electrician, however small the unit. Size is not what decides that – the 240V connection is.

Small drivers get tucked into the first convenient gap, and that is usually the mistake. Put it where a hand can reach it, not where it happens to fit, because the day it needs replacing nobody will remember where it went.

Frequently asked questions

What does an LED driver actually do?

It converts mains down to the low-voltage DC that LED fittings run on. Even a single small fitting needs one – low-voltage lighting cannot be connected to mains directly.

How much lighting will 25W run?

Add up the wattage of the fittings you want to power – the total needs to stay under 25W, with room to spare. The wattage of each fitting is listed on its own specification.

Does the output voltage have to match my fittings?

Yes. This driver outputs 12V or 24V DC and the fittings must be rated for the same. Mixing them either leaves the lights dead or destroys them.

Can it be installed outside?

No. At IP20 it has no weather protection, so it has to stay in a permanently dry location. Use a weatherproof driver outdoors.

What do I need to dim it?

A dimmer or control system that matches TRIAC (leading edge). The dimming happens at the driver, so the two have to agree.

Does it need an earth?

No. It is a Class II double-insulated driver, so no earth is required at the driver.

Do I need an electrician?

Yes, for the mains side. Connecting a driver to mains is licensed electrical work in Australia.

What warranty does it carry?

3 Years*
