The Domus DRIVER-12V-IP67 is an outdoor-rated 12V DC constant-voltage LEDdriver nine sizes from 20W to 500W,IP67, non-dimmable, complete with a 1m flex andplug.

This is the part that makes low-voltage lighting work. Every12V fitting in this catalogue LED strip, inground uplights, garden spikes, the ZOOM-PROspike lights needs a driver, and almost none of them include one. If you havebought low-voltage garden lighting and are wondering why it will not connect to mains,this is the missing piece.

How to size one the rule that stops drivers failing early

Add up the wattage of everything on the run, then add 20%.

• Ten 5W spike lights = 50W. Add 20% and you want a60W driver, not a 60W load on a 60W driver.
• Why: a driver run permanently at its ceiling gets hot, and heat is what killselectronics. Headroom is the difference between a driver that lasts and one that does not.
• Do not undersize and hope. An overloaded driver will flicker, shut down onthermal protection, or fail.
• Do not massively oversize either a 500W driver running a20W load is inefficient and wasteful.

Tell us the fittings and the run length and we will size it with you. Voltagedrop over a long cable run matters too, and that is not something a wattage total captures.

Constant voltage, and why 12V

• Constant voltage means it holds a steady 12V and the fittings draw what theyneed. That is what LED strip and most garden fittings are built for. It is not interchangeable with a constant-current driver, which is what manydownlights use. Check what your fitting needs.
• Parallel wiring fittings connect across the driver, not in a chain, so onefailing does not take the run down.
• 12V is safe to run through a garden. That is the real advantage of lowvoltage: cabling can be run with far less protection than mains, and a spade through a 12V cableis an inconvenience rather than an emergency.

IP67 and what the other numbers mean

• IP67 dust tight and protected against temporaryimmersion. That is a genuinely high rating: it can sit in a garden bed, in a pit, or anywherethat floods briefly.
• 40C to +60C, 2090% humidity,non-condensing.
• Efficiency up to 89% the share of mains power that reaches the lightsrather than becoming heat.
• Power factor >0.95 high, and it matters on a large installation.
• Protection: short circuit, thermal overload, over-temperature and over-voltage.

Even at IP67, mount it where you can reach it. A driver is the part most likelyto need replacing, and one buried under a paved path is a problem for later.

It does not dim. If you want dimmable low-voltagelighting you need a dimmable driver and a compatible dimmer ask us, because this is not it.

What we cannot tell you. The datasheet gives the physical size of the20W only 1504432mm,240g. The larger units are bigger and we do not hold their dimensions.Ask us before you size an enclosure or a cavity.

Warranty is 5 years among the longest in this catalogue, which isreassuring on the component most likely to fail first.

Where it works

• Powering 12V LED strip, inground uplights and garden spike lights.
• Outdoors and in wet locations IP67, temporary immersion.
• Retrofits where a driver has failed.
• Size it at load + 20%, and tell us the run length.
• Non-dimmable, and constant voltage check what your fittings need.

Questions

Which size do I need?

Add up the wattage of everything on the run and add 20%. Ten 5W spike lights is 50W, so you want the 60W driver not a 60W load on a 60W driver. A driver run permanently at its ceiling gets hot, and heat is what kills electronics. Tell us the fittings and the run length and we will size it with you, because voltage drop over a long cable run matters too.

What happens if I undersize it?

It will flicker, shut down on thermal protection, or fail. Do not massively oversize either a 500W driver running a 20W load is inefficient and wasteful.

What is “constant voltage” and does my fitting need it?

It holds a steady 12V and the fittings draw what they need, which is what LED strip and most garden fittings are built for. It is not interchangeable with a constant-current driver, which is what many downlights use check what your fitting requires before ordering.

Can it be dimmed?

No. For dimmable low-voltage lighting you need a dimmable driver and a compatible dimmer. Ask us this is not it.

Can it get wet?

IP67 dust tight and protected against temporary immersion, so it can sit in a garden bed, in a pit, or anywhere that floods briefly. It is rated 40 to +60C. Even so, mount it where you can reach it: a driver is the part most likely to need replacing, and one buried under a paved path is a problem for later.

How big is it?

The 20W unit is 150 44 32mm and 240 grams. The larger sizes are bigger and the datasheet does not record their dimensions, so ask us before you size an enclosure or a cavity.

Why 12 volts rather than mains?

Safety in a garden. Low-voltage cabling can be run with far less protection than mains, and a spade through a 12V cable is an inconvenience rather than an emergency. Fittings wire in parallel, so one failing does not take the run down.
