Meet ANKARLÄGG, an LED nightlight with sensor by IKEA
IKEA releases ANKARLÄGG, an LED nightlight with a sensor that attaches to any surface and glows without plugging in. Using two AAA batteries, the lightbulb-shaped device has no wires, no plugs, or no need for a mains connection. The nightlight works with a motion sensor, so it can ‘see’ movement. When someone walks within three meters of the light, it turns on automatically, but it does not stay on all the time.
It only lights up for 30 seconds before it turns off on its own again. The light only works in the dark, so during the day, it stays off, even if there is movement. Since the product controls itself, the batteries installed in the LED nightlight with sensor can last around six months of regular use.
