Walk the grounds of exclusive properties in the Algarve after dark and the lighting is often the thing that dates them: a row of bright spotlights aimed up at a palm tree, a floodlight over the gate, pool lights that turn the water a cold blue. Done well, outdoor lighting is barely noticed. Done badly, it dazzles the people who live there and everyone looking in from outside. The principles are simple, and they work as well on a terrace in Manchester as on a hillside in Portugal.
Go low and warm
Lights placed low, at knee height or below, show you where to put your feet without shining in anyone’s eyes. Choose warm-white bulbs of around 2700 kelvin. Cooler, bluer light looks harsh outdoors and draws more insects to the terrace. If a fitting doesn’t state its colour temperature on the box, put it back on the shelf.
Shield the bulb
A fitting with a hood or a downward-facing shade puts the light where you want it, on the ground, rather than at the sky or into the neighbours’ bedroom. Uplighting a tree can look good if the beam stays inside the canopy, but a bare spotlight angled upward spills light into the night sky. Look for fittings described as full cut-off, which means no light escapes above the horizontal.
Light the path, not the garden
Most gardens need light in only a few places: the steps, the front door, the route to the gate and the spot where people sit. Light those properly and the rest of the garden can stay dark, which makes the lit areas look more inviting. A garden lit from one end to the other tends to resemble a car park, and it costs more to run.
Timers, sensors and dimmers
A motion sensor on a side path or by the bins means the light comes on when someone needs it and goes off again. Put decorative lighting on a timer that switches it off at a sensible hour, whether that is eleven o’clock or midnight. A dimmer on the dining area lets you drop the light as the evening goes on, and it makes a surprising difference to how the space feels.
Think about wildlife
Moths gather around bright lamps and keep circling until they are exhausted, and several bat species avoid lit areas when they feed. A darker garden tends to have more going on in it after sunset. If you keep a pond or a hedge, leave a dark corner near it and point the lights away.
Low-voltage and solar options
Low-voltage LED kits are cheap to run and easy to install, and many can be moved around as the planting grows. Solar lights suit decorative jobs, such as marking the edge of a bed, but they are dim in winter and they don’t switch on reliably after a run of grey days. For anything you rely on, such as steps or a front door, a wired fitting is the better choice.
Check it from the road
Once the lights are installed, walk to the end of the drive or the street and look back. If you can see bare bulbs from there, so can everyone else. Adjust the fittings until you see pools of light on the ground and not the lamps themselves, and the garden will look better for it.
