Got A Light? Origin of the Flashlight
The tubular flashlight as we know it was invented in 1896 by David Misell. Before then people were left to very unsafe methods utilizing oil lamps for finding their way in the dark. Early flashlight models were very inefficient due to limitations in both battery and light bulb design. They were capable of producing only short pulses of light, hence the name flashlight. Also, they were big and bulky due the large size of the batteries at the time. Development of more reliable flashlights followed closely with the evolution of batteries and light bulbs. The invention of the smaller and lighter weight D cell battery in 1888 made possible the development of the first truly practical hand-held portable flashlight. Brighter and longer lasting light bulbs were made possible in1906 with the replacement of Edison?s carbon filament with tungsten.
