The First Arc Lamp is Invented
The first lamp that sheds artificial light is invented by Humphry Davy. -
The First Workable Incandescent Light Bulb
James Bowman Lindsay innovated it so that the light and the filament were contained in a glass bulb. -
Electrical Incandescent Arc Lamp
Edward Shepard created an electrical incandescent arc lamp with a charcoal filament. In the same year, Joseph Wilson Swan began working on an electrical incandescent arc lamp with carbonized paper filaments. -
First 'Modern' Light Bulb
Henricg Globel, a German watchmaker, used a carbonized bamboo filaments in a glass bulb. -
The First Practical, Long-lasting Light Bulb
Joseph Wilson Swan creatined the first long-lasting, practical light bulb, that lasted for 13.5 hrs, by using a carbon fiber filament. -
The First Oxgenless Light Bulb
Thomas Alva Edison made the first oxygenless light bulb by placing the carbon filament he made into an oxygenless bulb. It burned for more than 40 hours. -
An Even Longer Lasting Light Bulb
1880 - Edison continued to improved his lightbulb until it could last for over 1200 hours using a bamboo-derived filament. -
An Even Better Light Bulb
Willis Whitney invented a filament that would not make the inside of a lightbulb turn dark. It was a metal-coated carbon filament. This filament was a predecessor to the tungsten filament, our modern filament. -
Introduction of Tungsten Filaments
The General Electric Company were the first to patent a method of making tungsten filaments for use in incandesent lightbulbs, but the filaments were costly. -
Better Tungsten Filaments
William David Coolidge improved the method of making tungsten filaments. The tungsten filament outlasted all other types of filaments and Coolidge made the costs practical. -
The Modern Long-lasting Light
Philips invented a lightbulb that lasts 60,000 hours. The bulb uses magnetic induction.
