Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches ) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner.
The original Berger lamp used methyl alcohol, while modern lamps use isopropyl alcohol (90% or more). [5] Perfumes or essential oils may be added.

Burning fluid lamps had two long tapering wick tubes that looked like the letter V.

Camphine lamps had a single fixed wick with a flame spreader and a central draft system. [6] One type of camphine lamp was called a Vesta lamp. [23]
Jewelers and glassblowers engaged in lampwork have used the blowpipe since ancient times, with the blast being powered by the user's lungs. For small work, a mouth-blown blowpipe may be used with a candle flame or an alcohol lamp, with established techniques for applying oxidizing and reducing flames to the workpiece or
A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons , thyratrons , and ignitrons are used as switching devices in electric devices.
