The invention of the flashlight was preceded by the invention of electric battery and light. In 1895, David Missel invented the flashlight. It was a paper tube structure with a light bulb and brass reflector at one end and ‘D’ batteries from front to back that helped power it. The initial flashlights used zinc-carbon batteries to power them but they had their own limitations. These batteries did not give stable electric current and required rest at regular intervals to function. Due to the brief flashes during which they gave light, the device was called flashlight. In 1906, tungsten filament lamps were introduced that had thrice the efficiency of the older versions and used improved batteries, which made it popular. The light was instant and there was no flame that made these lights usable. Improvisations were made and by 1922, there were different sizes and types of flashlights available in the market.
