The flashlight was invented in the late 19th century, with the first portable electric light emerging in 1899. Its development was largely attributed to the invention of the dry cell battery, which allowed for a compact and portable power source. Earlier versions utilized incandescent bulbs, but modern flashlights have evolved to use LEDs for greater efficiency and brightness. The flashlight has since become an essential tool for various applications, from household use to outdoor activities.
