Most of the bulbs in circulation are reproductions of the wound filament bulbs made common by Edison Electric Mild Company at the turn of the twentieth century. They are easily recognized by the lengthy and complicated windings of their inner filaments, and by the very heat-yellow glow of the light they produce (most of the bulbs emit light at a coloration temperature of 2200-2400 Ok). These carbon filament bulbs, the primary electric mild bulbs, became available commercially that same yr. The introduction of a neutral gasoline to the glass envelope (or bulb) additionally helped to enhance the lifespan and brightness of the bulb. To supply enough light, these lamps required the use of extraordinarily lengthy filaments, which remained so till the event of more efficiently wound tungsten filaments.
