Then the invention of ductile tungsten, a much improved filament material, sparked the development of the modern tungsten filament incandescent light bulb by the General Electric Company and William Coolidge in 1906-10. This is the light bulb we know today.

A tungsten filament is drawn to a very uniform diameter when it is manufactured. As a result, when a light bulb is first turned on the filament emits light relatively evenly along the length of the filament. Explore the failure of a filament using the following movie which shows an accelerated view of a filament failing.

Along the timeline of the background investigations, it was found that both the proton and X-ray fluxes at GOES 8 have had good correlation with changes in the resistance or increases in the noise (variance) of the tungsten filament.

The tungsten filament of a vacuum incandescent lamp is heated to temperatures where visible light is emitted by resistance heating. The filament acts as an electrical resistor, which dissipates power proportional to the voltage applied, times the current through the filament.
