Light in a transparent protective case WordNet 3.0 & Open English WordNet

A lantern is an often portable source of lighting, typically featuring a protective enclosure for the light source – historically usually a candle, a wick in oil, or a Thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors.
