How hot does a tungsten filament get in a lightbulb?
4,500 degrees Fahrenheit
A tungsten filament inside a light bulb can reach temperatures as high as 4,500 degrees Fahrenheit. A glass enclosure, the glass “bulb”, prevents oxygen in the air from reaching the hot filament.
How high a temperature can a tungsten filament withstand?
about 2500 °Celsius
Temperature of an Incandescent Light Bulb

| Bloomfield, Louis A. Incandescent Light Bulbs. How Things Work. University of Virginia. | “The tungsten atoms and the filament become extremely hot, typically about 2500 °Celsius.” | 2800 K |
What temperature are tungsten lights?
around 3000° K
For tungsten (wolfram) filament light, the working color temperature is around 3000° K, and more than three-quarters of the energy is radiated in the infrared region in the form of heat.
What is the operating temperature of a light bulb filament?
An electric current heats the filament to typically 2,000 to 3,300 K (1,730 to 3,030 °C; 3,140 to 5,480 °F), well below tungsten’s melting point of 3,695 K (3,422 °C; 6,191 °F). Filament temperatures depend on the filament type, shape, size, and amount of current drawn.
How hot does a 60 watt lightbulb get?
Firstly, the 60-watt bulb can get up to 200F on the glass surface. The fluorescent 60 watt works differently to produce light, so only 30% of heat is produced. With a standard bulb, you’ll have 90% that’s typically emitted. The fluorescent bulb will be warm to the touch between 50-60 Fahrenheit.
How hot does a 60 watt bulb get?
120 degrees Fahrenheit

Does tungsten have high resistance?
Complete step by step answer It is a fact that we use tungsten for a filament. Tungsten has a high melting point and high resistivity.
How do you calculate filament temperature?
α is the temperature coefficient of resistance, which is tabulated for different materials on the attached sheet. In your case the filament is made of tungsten. a) Show that the formula above is equivalent to T = T0 + (R/R0-1)/α .
What is the temperature of sun?
