The delightful Animal Eco Torch is dynamo powered which to put it in simple terms is powered by winding up the torch. Use the handle located on the side of the Animal Eco Torch to power the torch and one minute of winding up the torch powers the torch for an amazing 20 minutes of light. The light within the Animal Eco Torch is a super bright LED bulb and offers great reassurance to children whom may be scared of the dark. A great addition to any sensory den.
