US inventor Thomas Edison is often credited with creating the solution in 1879: the carbon filament light bulb. Yet the British chemist Warren de La Rue had solved the scientific challenges nearly 40 years earlier. He used thin – and thus high-resistance – filaments to achieve the brightness, and delayed burnout by making them from high-melting-point metal sealed in a vacuum. His choice of pricey platinum for the filament and the difficulties of achieving a good vacuum made the result uneconomic, however. In 1878, another British chemist, Joseph Swan, publicly demonstrated the first light based on commercially-viable carbon, but his use of relatively thick filaments still led to rapid burnout. Edison’s combination of thin carbon filament design with better vacuums made him the first to solve both the scientific and commercial challenges of light bulb design.

In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.
