70,000 BCE Hollow rocks or shells or other natural found objects were filled with moss or a similar material that was soaked in animal fat and then ignited.
4500 BC Oil lamps began to appear.
3000 BC Candles were invented.
Invented in 3000 bc, candles were still a primary source of light in the Seventeenth Century. (Courtesy Philips)
900 BC Muhammad ibn Zakariya Razi, a Persian scholar, invented the kerosene lamp.
1780 Aimé Argand, a Swiss physicist and chemist greatly improved oil lamp efficiency and performance with improved oils and the use of glass chimneys to draft the flame.
1792 William Murdoch, Scotland, began experimenting with gas lighting and probably produced the first gas light in this year.

1841 Arc-lighting used as experimental public lighting in Paris.
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.
1867 A. E. Becquerel, France, coated electric discharge tubes with luminescent materials, a process that was further developed in later fluorescent lamps.
1875 Henry Woodward, Canada, patented an electric light bulb with carbon filament.
