Our Brass Oil Lamps is 13" overall. The fuel reservoir of the large lamp is larger which ensure it burns for many hours. What makes this particular lamps exceptional is the tall, narrow glass chimney, along with the special design of the wick and its unique elevation mechanism. The result is a much bigger flame that can actually extend smoke-free all the way up the chimney, if desired, producing a surprising amount of light. We are delighted by them because, although a modern design, they have the inherent charm of a 19th Century lamp but throw a lot more light. Will burn either standard lamp oil or kerosene (easily available locally). 13" tall x 4" width (max). The glass chimney is 7-3/4" tall. We suggest you fill it with a funnel (not included) to prevent spilling.
