A flashlight is a portable lighting device powered by one or multiple batteries. It consists of a light source, typically an incandescent bulb, LED, or fluorescent lamp, and a reflector that directs the light in a specific direction. Flashlights are commonly used for illuminating dark areas, such as during power outages, camping, and hiking, and they can also be used as signaling devices or for self-defense.
The first flashlights were invented in the late 19th century, and they have since become an essential tool for people around the world. Flashlights are relatively inexpensive, easy to use, and can provide a powerful source of light in even the darkest of conditions. They are also durable and can withstand being dropped or knocked around, making them ideal for use in a variety of situations.
