A gas lamp includes first and second main structures. The first main structure forms a foundation of the gas lamp and includes a reservoir as a fuel tank. The second main structure is directly and releasably mounted atop of the first main structure. The second main structure includes a fluid guiding member, a carrier mechanism, a covering member, and a shield. The fluid guiding member defines a fluid entry zone and a fluid acceleration zone. The covering member includes the fluid acceleration zone circumferentially surrounded therein. The gas lamp includes the carrier mechanism adapted to be grasped, which facilitates disengagement of the first and second main structures for fuel refill and easy transportation of the second main structure.
