Mantle lamps typically use fuel faster than a flat-wick lamp, but slower than a center-draft round-wick, as they depend on a small flame heating a mantle, rather than having all the light coming from the flame itself. Mantle lamps are nearly always bright enough to benefit from a lampshade, and a few mantle lamps may be enough to heat a small ...
While electric lighting was introduced to theatre stages, the gas mantle was developed in 1885 for gas-lit theatres. "This was a beehive-shaped mesh of knitted thread impregnated with lime that, in miniature, converted the naked gas flame into in effect, a lime-light."

To produce a mantle, cotton is woven or knit into a net bag, impregnated with soluble nitrates of the chosen metals, and then transported to its destination. The user installs the mantle and then burns it to remove the cotton bag and convert the metal nitrates to ...

The Coleman Lantern is a line of pressure lamps first introduced by the Coleman Company in 1914. This led to a series of lamps that were originally made to burn kerosene or gasoline.

A lantern is a source of lighting, often portable. It typically features 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.
