Plug-In LED Night Lights, 2700K

These plug-in night lights do exactly one job and require nothing from you afterwards. A built-in dusk-to-dawn sensor brings each light on as the room darkens and switches it off again in the morning, so there is no switch to find at two in the morning and no light burning pointlessly through the afternoon while nobody is home to see it.

The colour temperature matters more than most people expect. At a warm 2700K the glow is amber rather than blue-white, which is far kinder to adjusting eyes in the middle of the night and much less disruptive if the light is near a bed. It is bright enough to show a step, a doorframe or a light switch, and dim enough to sleep beside.

They suit bedrooms, bathrooms, hallways, landings, kitchens and nurseries, and the compact body sits close to the wall so it does not block the second socket in a double outlet. There are no batteries to replace, no timers to programme and no maintenance beyond an occasional wipe with a dry cloth. Plug them into a dry indoor socket only, keep them clear of curtains, bedding and anything else that traps heat, and check they sit flush in an older or loose outlet.
