150W Weatherproof Dimmable LED Driver

150W 12V or 24V weatherproof LED driver

This is a mid-sized LED driver - the power supply that sits between mains and low-voltage lighting. This is the size most domestic jobs land on: a room of strip lighting, a garden bed of spike lights, or a run of step lights down a staircase. It takes mains power and converts it down to 12V or 24V DC.

It is rated to carry up to 150W of LED load. That figure is a ceiling, not a target - which matters more than it sounds.

At this size the driver stops being an afterthought and starts shaping the installation. It has to live somewhere reachable, it has to be allowed for in the cabling, and it is the component most likely to want attention before the fittings do.

Working out what size you need

Add up the wattage of every fitting on the run, then choose a driver rated comfortably above that total rather than one that just covers it. Running a supply at its limit is the most common cause of early failure: it runs hotter, and heat is what kills a power supply.

Spare capacity is also what lets a scheme grow. Gardens and rooms gain fittings over time, and a driver chosen with headroom absorbs that; one chosen exactly does not.

⚠ 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

Outdoors, the question is less whether it survives and more whether you can get back to it. A driver buried at the far end of a garden bed is protected and effectively unreachable; one at the start of the run, off the ground and clear of planting, is both.

Weatherproof is not the same as submersible. Keep it out of standing water and off ground that floods, and mount it so water runs off rather than pooling on it.

Dimming

This driver is dimmable. Dimming a low-voltage LED system happens at the driver rather than at the fitting, so check that your dimmer or control system matches the driver's dimming method before ordering.

Installation

This is a Class I driver, which means it requires an earth connection. That is not optional, and it is part of what makes the installation compliant.

The mains side of a driver is licensed electrical work and must be wired by an electrician. Decide where the unit will live before the lights go in: it needs to stay reachable, because it is the part most likely to need attention years down the track.

Give it air. A driver at this capacity sheds real heat, and one packed into insulation or sealed into a tight box will run hot and shorten its own life whatever its rating says.
