This versatile night light features a motion sensor function, so will light up automatically when movement is detected between 2to 3metres of the sensor, which is located towards the base of the product. The light can be used in any room of the house, but is especially useful in children's bedrooms. Simply plug the night light in & switch it to the on position if you want a constant light from the 5 bright white LEDs housed within, or to the automatic position if you'd prefer it to illuminate only when it senses movement. The torch function of this product is incredibly useful, since the light can be removed from its plug-in case & used mobile, wherever you choose. If used in a child's bedroom, its easy for them to safely pick up & take it with them to light their way! It can then be replaced to its case, where it will charge automatically, via electromagnetic induction, when plugged in.
