A lamp includes a fuel reservoir, a hollow wick, and an air channel. The fuel reservoir is configured to hold a volume of fuel. The hollow wick is configured to wick the fuel from the fuel reservoir to the atmosphere such that a flame is produced when the wick is ignited. The air channel is configured to supply air from outside of the fuel reservoir to a base of the flame. The air channel extends through the hollow wick and is at least partially graduated so that the flow of air through the air channel is substantially laminar.
