A lantern is a portable lighting device used to illuminate broad areas. Lanterns may be used for signaling, or as general light sources for camping. Dim varieties are often used for decoration. The kerosene lantern, also popularly referred to as a hurricane lantern was commonly used from the late 1800s through the middle of the 20th century. A kerosene lantern is a rugged version of a kerosene lamp and is designed for portability. The metal chimney and side tubes, which securely supports the glass globe to prevent breakage, typically contains a ducting system to stabilize and enhance the draft of air reaching the flame resulting in a stable, brighter, wind resistant flame. Lanterns with enhanced drafting are referred to as either hot blast or cold blast tubular lanterns, depending on their design, with the latter being more common.
