Kerosene lamps are portable lighting devices that use kerosene as fuel. They consist of a glass container to hold the fuel, a wick that draws the kerosene up, and a flame that produces light when the wick is lit. These lamps have been used for centuries, especially before the widespread availability of electricity. The design of kerosene lamps can vary, but they typically feature a chimney to protect the flame and improve airflow. They are often used in areas without electricity or during power outages. Kerosene lamps are valued for their simplicity and effectiveness in providing light in dark environments.
