An incandescent lamp is a type of electric light that produces light by heating a metal filament until it glows. This process occurs when an electric current passes through the filament, typically made of tungsten, which has a high melting point. Incandescent lamps are known for their warm light and ability to render colors accurately. These lamps are commonly used in homes and businesses, but they are less energy-efficient compared to other lighting options like LED or fluorescent lamps. As a result, many countries have implemented regulations to phase out incandescent bulbs in favor of more energy-saving technologies.
