A Coleman white gas lantern mantle glowing at full brightness. An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century.
Mantle lamps are considerably brighter than flat- or round-wick lamps, produce a whiter light and generate more heat. 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.
Gas lighting in the historical center of Wrocław, Poland, is manually turned off and on daily.. Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas (town gas) or natural gas.
This led to a series of lamps that were originally made to burn kerosene or gasoline. Current models use kerosene, gasoline, Coleman fuel or propane and use one or two mantles to produce an intense white light. Over the years more than 50 million of the lanterns have been sold throughout the world. [2]
Petromax is reliable and efficient light source but only with proper use and well maintained. Typical problems leading to malfunction of the lantern: Misuse (no sufficient pre-heating or forgetting to pressurise the fuel tank) Broken seals or loose joints or leakage in the container (pressure and/or fuel leaks at the wrong place)
