Motion sensor light for stairs
Updated: 20.10.2026
You get up at 2 a.m., the landing switch is behind you, and you want to see the first tread before you step. A motion sensor light for stairs can show that tread without a bright ceiling lamp. It will not, by itself, cut the number of falls, and it is not a handrail. The [motion sensor battery comparison](/hub/burglar-protection/motion-sensor-battery) holds the twelve indoor lights. This page is the route: where the first light sits, how bright it should be, and when a puck is the wrong tool. Cupboard task lighting stays on the buying guide. A qualifying purchase can earn us a commission at no extra cost to you.

What a stair light can and cannot do
RoSPA’s Safer Stairs campaign reports over 1,000 deaths and 43,000 hospitalisations a year in England and Wales. It is about stair design, including BS 5395-1, not LED pucks. HSE RR1228 quotes over 700 deaths a year in England. Do not blend those figures, and do not claim a battery light reduces them.
What a light can do is smaller. It can come on before you commit your weight, in a warm colour, and switch off so the house is not lit until morning. A light on a broken nosing does not repair it.
Top, bottom, and across the walk
Put the first light where it sees you before the first tread. On a straight flight that usually means one light at the top landing, aimed across the walk, and another at the bottom if the top sensor will not cover the lower steps. Listed ranges run from about 6 feet to 16 feet, and a seller’s range is not a measured test.
A half-landing often needs its own light, because the turn hides the lower flight. Two lights is a fair start on a straight flight. Three is fair once there is a turn. Eight pucks are not safer than two well aimed ones. Aim low enough that the beam hits the treads. How to stick the pad is on how to fit a battery motion sensor light.
Warm, brief, and not a ceiling flood
Warm and dim is the landing brief. The Auraglow AG708, £9.99, holds a warm glow for 20 seconds and has a permanent on mode if someone pauses. The Detake, £13.49, is about 4,000 K and off after 30 seconds. The 7 inch bar lists up to 80 lumens and a swivel.
The BLS is 7,000 K, with 250 lumens in the bullet and 180 in the table. On a bedroom landing that is more likely to wake the house than a warm 80-lumen bar. The RAWNICE panel’s claimed 400 lumens is the same risk unless you dim it. The buying guide separates night-light level from cupboard task light. Auto-off fails if someone stops on a step.
When you need more than a puck
A missing handrail, a steep flight, or a nosing you cannot see even with a light, is no longer a lamp problem. Do not remove a handrail because a puck is on the wall. A rebuild is a joiner. A fixed 230 V luminaire on a new circuit is an electrician. These battery lights sit below the voltage band in the Electrical Equipment (Safety) Regulations 2016, so sticking one up is not that circuit.
A puck on the dry side of the bathroom door can mark the path. It cannot go in the shower. None of these listings states IP44 or IP65. A swollen pack, or a sensor that still runs all day after night-only is set, goes back under the Consumer Rights Act 2015. Cell life on a busy landing is on rechargeable or alkaline.
Common questions
Where do I put the first light so it is on before I step?
At the top landing, aimed across the walk, low enough to wash the first treads. You should be in the field while you are still on the flat. A sensor that looks up the flight often comes on late. Add a second light at the bottom if the listed range, often only 2–5 metres and only a seller figure, does not reach.
How many lights does a half-landing need?
A straight flight often works with one at the top and one at the bottom. A turn needs a light of its own, because the upper sensor cannot see around the corner. Two or three is the practical range. Eight pucks do not add a margin the reviews can show, and the AmmToo eight-pack shares its reviews with the four-pack.
Will a cool white bar wake the house?
It is more likely to than a warm dim light. The BLS is 7,000 K, with 250 lumens in the bullet and 180 in the table. The 7 inch STAR-SPANGLED bar lists up to 80 lumens in a warm colour. The Auraglow is a warm glow with no lumen figure. Dim the RAWNICE if that bright panel is the one on the landing.
Is this enough if the stair has no handrail?
No. A light shows the step. It does not replace a handrail or a sound nosing. RoSPA’s figures are a design campaign, not a test of these LEDs. If the handrail is missing, sort the stair. The puck can mark the route while you do. It is not the repair.
Can the same puck live by the bathroom?
On the dry side of the door, if you accept there is no IP rating. Detake and Auraglow reviews include bathroom trips. The Auraglow listing says not water resistant. Do not move the same puck into the shower. That zone needs a bathroom-rated fitting.
Should the sensor face up the stairs or across the landing?
Across the landing. These PIRs notice someone crossing the field more readily than someone walking at the lens. Facing up the stairs often triggers after you have started down. Keep the lens off a radiator and off another lamp, or it chatters at the wrong moment.
What brightness is enough to see a tread and not dazzle?
The warm listings people describe on stairs are the Auraglow glow, the Detake at about 4,000 K, and the 7 inch bar at up to 80 lumens. Four hundred lumens, the RAWNICE claim, is a lot unless you dim it. Fifty lumens, the Oumida figure, is a marker rather than a work light. No lumen line means you find out after dark.
