Motion-sensor lighting for stairs and hallways
About 15 minutes
Stairs and hallways are where a light has to work hands-free, because you are usually carrying something or half asleep when you pass through them. A motion-sensor lamp solves exactly that: it switches on as you approach and off again after you have gone, so the dark is lit only in the moment it needs to be. This is how to place one so it actually catches you on the way through, and how to choose between the ways these particular lamps are powered.
What you need
- A motion-sensor lamp with a USB charge
- A mounting spot at the top or bottom of the dark stretch
Step by step
- Find the approach path. Stand where the dark stretch begins and work out the line someone walks in from, then face the sensor across that line.
- Aim it across the treads. On stairs, angle the lamp down the run so it skims the edges of the treads rather than shining up into your eyes.
- Choose the sensing mode. Set it to induction for night-time use, or cycle to night sensing so it stays off during daylight hours.
- Charge it and forget it. Top the battery up over USB and keep it on motion, not always-on, so a charge lasts.
Place it where you enter, not where you stand
A motion sensor sees a cone of movement in front of it, so the light wants to sit where your approach passes through that cone before you reach the dark bit. For a stair, that means at the top or bottom facing the steps rather than halfway along them, where you would already be committed.
For a hallway, mount it at the point you enter rather than the far end. The light should come on as you arrive, illuminate the route, then hand you off to the next room. A sensor that only triggers once you are already past the dark stretch is a light that came on too late.
On stairs, aim low and down the run
The thing a stair light is for is the edge of each tread, which is where a foot actually lands. Attach the lamp facing down the run of steps from the top or up from the bottom, angled so the light skims across the treads rather than up into your eyes.
Because the lamps here are self-contained, you can test the angle for a night or two before settling. Move it until you can read the treads clearly from the top without the light source itself sitting in view.
Rechargeable means no mains work
These lamps run on a built-in battery topped up over USB rather than a wired supply, which is what lets one go anywhere there is motion but no socket — under a stair, inside a cupboard, along a corridor. There is no wiring to run and no electrician to involve.
The practical question is how often you charge. A lamp that comes on for only a few seconds at a time on its motion setting lasts a long while between charges; one left in an always-on mode all evening drains far sooner. Save always-on for when you are actually in the room.
Match the length to the run
One lamp cannot see around a corner, so a landing with a turn in it usually wants one at each end rather than one bright lamp in the middle. The job is to keep the whole route lit, and a sensor only covers so much of it.
The bar lamp here comes in 10, 20, 30 or 50 cm lengths, so you can match the lamp to the space. A short bar suits a landing or a cupboard; the longer sizes suit a full flight of stairs, where more treads are lit from a single position.
Colour and a mode for the daylight
Colour temperature matters on stairs because the light appears in a moment of low light, and a harsh cold white is more startling than a warm one. The lamps offer a choice of cool white, warm white or a three-colour option, so you can match the rest of the house.
The sensing itself can be tuned too. The bar lamp switches between an induction mode and always-on, and the cabinet-style bar cycles through always-on, night sensing, all-day sensing and off from the light itself — so a lamp in a dark cupboard can stay dark all day and only wake when you reach in.
