Tungsten lamps are a type of incandescent light bulb that use a tungsten filament to produce light. When electricity passes through the filament, it heats up and emits a warm, yellowish glow. These lamps are known for their ability to render colors accurately, making them popular in photography and film. Tungsten lamps are often used in various applications, including stage lighting and household fixtures. They are available in different wattages and sizes, providing flexibility for different lighting needs. However, they are less energy-efficient compared to other lighting options, such as LED or fluorescent lamps.
