8 inch nylon ball lanterns. Fine in rain, fine in sun, fine at night, even fine in the rain.
These are safe no matter what the weather is like. Check out how nice they look catching the sun and not just with a light in at night.
Due to a wire frame the lanterns are held in a tight ball shape. The top of this frame is where the light cord is slipped into, to sit there and be held by double kinked friction.
