To use this lantern, simply plug it into a 110V US power outlet. You can hang it outside your home using a hook or a string. There are different LED show options, so you can switch between them to get the effect you like. When it comes to maintenance, keep it away from water and direct sunlight. If it gets dirty, you can use a soft, dry cloth to gently wipe it. Make sure to turn it off and unplug it before cleaning. Enjoy this wonderful lantern during the Christmas season!
