Choosing a plug-in night light for a child's room or landing

What you need

• A working socket in each dark spot
• The light source facing into the room, not at the bed or door

Step by step

1. 1Walk the route in the dark. Switch the lights off and walk from the bed to wherever someone goes at night, and note every dark stretch that needs marking.
2. 2Pick brightness and colour. Choose soft white or 3000k warm white, and the dimmest pack that still marks the stairs, the step edges and the door.
3. 3Let the sensor switch it. Plug it in low and offset from the doorway, then leave it — the sensor brings it on at dusk and off at dawn by itself.

How much light do you actually need

For a landing or a child's room the honest answer is less than you think. A night light is there to outline the floor, the door and the edge of a bed, not to light the room for reading. The plug-in lights here sit in that narrow band: one pack runs at 40 lumen and the other at 50 lumen, both low enough to guide without dazzling.

The usual mistake is treating dimmer as worse. A light bright enough to read by becomes a nuisance at two in the morning — it lights the ceiling, it leaks under the door, and it is enough to pull a child awake. The right night light is the dimmest one that still marks the hazards: the top of the stairs, the edge of a step, the door handle.

Warm white reads calmer

Colour temperature is the difference between a light that feels cold and one that feels like the last lamp on in the house. The two packs are not identical here: one is a soft white and the other a 3000k warm white, which sits at the amber end of the scale.

For a child's room and a landing at night, warmer is the safer choice. Warm light does not read as daylight pushing in, so it does not look like morning or like something switched on by mistake. It is the difference between a light that fits the quiet of the house and one that stands against it.

The sensor should do the switching

The single most useful feature on a plug-in night light is that you never touch it. These lights have a built-in sensor that turns them on when the room gets dark and off when it gets light, so they are only ever on when a dark room actually needs them. Nothing to remember and no timer to set.

One of the packs also brightens as the room darkens further, which matters on a landing that gets a little borrowed light from downstairs early in the evening and none at all after midnight. A fixed light has to be set for the darkest moment; a sensor can edge its way up as the house settles.

Two lights or eight

How many you buy is really a decision about how many rooms and how many outlets. A two-pack covers a single landing, or a child's room plus the bathroom; an eight-pack treats the night light as a whole-house thing — every hallway, the kitchen for late trips, the nursery.

There is no magic number, but a useful test is to walk the route someone actually takes at night with the lights off and count the dark stretches between the bed and wherever they are going. Each genuinely dark stretch wants a light, and the difference between the two packs is simply how many of those stretches you have.

Where the plug goes

A plug-in night light has to be at a socket, so placement is partly decided for you. As a rule you want it low — near the floor it is lighting, near the ceiling it is glare — and you want the light source facing into the room rather than straight at a bed or a doorway.

The usual mistake is putting it directly under the thing it is meant to reveal, so the bulb is what somebody looks at. Offset it slightly, on the wall the door opens against, and the glow lands where it is useful — on the floor, not in the eye.
