A torch is a portable device that produces light, typically powered by batteries or fuel. It is commonly used for illumination in dark areas, such as during camping, hiking, or power outages. Torches come in various designs, including handheld flashlights and larger lanterns, and can vary in brightness and battery life. Modern torches often use LED technology, which provides bright light while consuming less energy. Some torches are also designed to be waterproof or impact-resistant, making them suitable for outdoor activities. In addition to recreational use, torches are essential tools for professionals in fields like construction and emergency services.
