The gas also acts to extend the life of the filament. The filament is a piece of thin coiled wire and is part of the light bulb that produces the light and is usually made out of tungsten -- ... "When electric current flows through the filament, it heats the filament to a temperature of about 3000 °C (about 5000 °F),

The light emitted by the filament is thermal radiation and its color spectrum and brightness depend almost exclusively on its temperature. These 130-volt bulbs emit redder and dimmer light than a normal bulb and they are significantly less energy efficient as a result.

Hot, really hot. Typically in the range of about 2000C to 2500C (3600F - 4500F). It would be pretty difficult to directly measure the temperature of the filament so you have to use something other than a thermometer for the measurement. It ...

The filament temperature will be hard to get given only bulb surface temperature measurements. However, the color of the filament is a direct indication of the temperature. Devices called optical pyrometers are used to take this type of mea...

The tungsten filament of an incandescent light bulb at full brightness is somewhere around 5500°C. Of course it depends on the wattage of the bulb. The filament is a "blackbody radiator" whose temperature is linked to its color. Y...
