Check the listing for details. Aladdin Brass Heel-Less Gallery. Color: Brass, Condition: New. Listed at 34.95 USD. An Aladdin heelless gallery, also known as a "heelless lamp chimney" or "Aladdin lamp chimney," is a specific type of chimney designed for Aladdin lamps. Aladdin lamps are a brand of pressure lamps that use a mantle to produce a bright, white light by burning kerosene or other fuel. The heelless gallery refers to the design of the bottom part of the chimney, which lacks a protruding lip or "heel" that is commonly found in traditional lamp chimneys. The absence of a heel in the gallery allows for a more efficient and consistent airflow, which is crucial for the proper operation of the Aladdin lamp. This design feature ensures that the mantle receives the correct amount of oxygen for combustion, resulting in a brighter and more consistent light output.
