Product description
A flashlight is a handheld electronic lighting tool. A typical flashlight has a battery powered bulb and a focusing mirror, as well as a handheld case for handheld use. Although it was a fairly simple design, it was not invented until the late 19th century because it had to be combined with the invention of batteries and light bulbs.
