Flashlight (English: Flashlight or Torch), or Flashlight, is a hand-held electronic lighting tool. A typical flashlight has a battery-powered bulb and a focused reflector, and has a hand-held hand-held shell. Although it was a fairly simple design, it was not invented until the late 19th century, because it had to combine batteries with the invention of the electric light bulb. In the early days it was called "Flashlight" because of the lack of electricity in the battery.
