   Current through the filament (tungsten wire, melting point of more than 3000 degrees Celsius) to produce heat, spiral filament will continue to heat accumulation, making the filament temperature of 2000 degrees Celsius above the filament in the incandescent state, like the red iron Glowing and glowing. The higher the temperature of the filament, the brighter the light emitted. The When the Edison bulb glows, a lot of electricity will turn into heat, and only a small part (possibly less than 1%, no calculations) can be converted into useful light energy. The Edison bulb is light-colored, but the composition of the various shades is determined by the luminescent material (tungsten) and the temperature. The proportion of imbalance led to the color of light color, so Edison bulb can send brilliant light. Applied to a variety of decoration.
  The life of the Edison bulb is related to the temperature of the filament, because the higher the temperature, the easier it is to sublimate the filament. Fluorescent lamp at both ends of the process is: tungsten wire sublimation directly into tungsten gas, these tungsten gas encountered lower temperature of the lamp wall and condensate in the lamp wall and black, when the tungsten wire sublimation to relatively fine Thin, it is easy to burn after power, which ended the lamp life. So, the greater the power of the Edison bulb, the shorter the life you use.http://www.outedsionbulb.com/
