Begin with the Job the Lantern Has to Do

A porch lantern is not really decoration first. It is a working light with two clear jobs: making the way to your door safe to walk, and making the face of whoever is standing there readable. Get those right and the lantern will also look lovely, but the order matters. Plenty of front doors are lit by a fitting that throws a bright glare into the street while leaving the step, the keyhole and the visitor in shadow.

So picture the scene from the end of the path. You want a soft pool of light roughly 1.5 to 2 metres wide, centred on the door, bright enough to pick out door numbers and door furniture without bleaching the brickwork. Aim to light the person, not just the doorway. That single change of thinking guides every decision below, from where you fix the lantern to which bulb you screw into it.

Height, Position and the Size of the Pool

Mount a wall lantern at roughly 1.8 to 2.1 metres above ground level — around or slightly above eye height. Any lower and it glares straight into a visitor's eyes; any higher and the light spreads too far and gets lost before it reaches the doorstep.

• Single lantern: fit it on the handle side of the door, so keys, locks and the letterbox all fall inside the light.
• Twin lanterns: space them evenly either side of a double door or a wide façade, usually 1.2 to 1.5 metres apart, and keep them at the same height to the millimetre.
• Clearance: leave at least 30 centimetres between the top of the lantern and any eaves, soffit or door canopy, so heat and light are not trapped against the wall.
• Deep porches: a wall lantern beside the door will still give the best facial light. A ceiling fitting can add a gentle wash, but rarely lights a face well on its own.

If your path curves or you have steps, walk it at dusk after fitting. Any dark patch where a foot might land needs attention — a small matching post light or step light solves it neatly.

Warm Bulbs, Plain and Simple

Colour temperature does more for a front door than almost anything else. Choose a warm white of 2700K or lower, and around 2200K if you want that soft, almost candle-like glow that flatters brick, stone and painted timber. A 4000K cool white bulb will make a handsome Georgian door look like the entrance to a car park.

Modern LEDs have made life easier here. A 4 to 6 watt lamp is usually plenty in a wall lantern, and you are looking for roughly 300 to 500 lumens per fitting at the door. Check the fitting's maximum wattage before you buy, choose dimmable lamps if there is a dimmer indoors, and look for a colour rendering index of 80 or above so faces and flowers keep their natural colour. Never exceed the rating printed inside the lantern.

Shades That Send Light Down, Not Up

Upward glare is the most common fault in porch lighting, and it is nearly always caused by an open-topped lantern with a bare bulb inside. The fix is in the shade, not the bulb.

• Choose downward-facing lanterns or designs with a solid, opaque top and glazing around the lower half.
• Frosted, opal or ribbed glass softens the image of the lamp itself, while seedy or slightly textured glass scatters light pleasantly across the doorway.
• Louvres and baffles inside a lantern cut the harsh bright spot without losing output.
• Hooded coach lanterns with a small finial and a closed crown are a classic solution that still looks traditional.

Test it honestly: stand two or three metres back down the path at dusk. If you can see the bare lamp, it will glare. If you can see the door and the step, you have got it right.

Styles and Materials for British Front Doors

Period properties tend to take a six-sided lantern in black metal or aged brass, ideally with a modest finial and a shape that echoes the door's glazing bars. Cottages and rural homes suit a wrought-iron style bracket lantern on a short arm, which throws light down the wall as well as across the step. Contemporary houses look best with restrained shapes — a matte black box, a simple cylinder, or a slim vertical slot — kept to the same finish as the door handle and house number.

On materials, solid brass weathers gracefully and can be left to patinate or polished back. Powder-coated cast aluminium is the low-maintenance option and stands up well to British weather. If you are within a mile or two of the coast, choose a marine-grade finish and expect to rinse salt off the glass and metal a few times a year.

Wiring, Controls and the Small Details

Outdoors, everything needs a suitable ingress protection rating: IP44 as a minimum, and IP65 for a fully exposed or coastal position. New circuits and any work in a special location should be carried out by a registered electrician, with RCD protection on the circuit; in England and Wales, notifiable work falls under Part P.

For controls, a well-aimed PIR sensor is a joy and a badly aimed one is a nuisance. Point it away from the pavement, trees and next door's cat, and set it so the light comes on as a visitor turns in at the gate rather than as they reach the step. A photocell or dusk-till-dawn setting gives you a low background glow all evening, and if you have the wiring for it, two circuits — a dim always-on one plus a brighter sensor-triggered one — is the best of both worlds.

Finally, the details that keep it working: drill cable entries so water runs out rather than in, seal glands properly, use an outdoor-rated connector, and clean the glass with a damp cloth every few months. When a lamp fails, replace both lanterns at once so the colour and brightness stay perfectly matched. A little attention now means a warm, welcoming doorway every evening for years.
