Electrical Lighting Overview in its early days
The first electric lamp was the CARBON-ARC LAMP, demonstrated in 1801 by Sir Humphrey Davy, an English chemist.
in 1854 Heinrich Göbel, Germany, invented an incandescent lamp by passing an electric current through a carbonized bamboo filament that was placed inside of a glass bulb. http://www.ies.org/lighting/history/timeline-of-lighting.cfm
