Heya friend!!
Rajdeep here...
First of all, let me tell you, that tungsten is a poor conductor of electricity, i.e., its resistivity is very high, so when current is passed through it, it gets heated up to the extent that it glows. Further, its melting point is very high (=3000K), so it won't melt if a temperature less than that is reached.
Now, an incandescent bulb with a tungsten filament generally operates at 2500K.
Hope my answer is satisfactory...
Thanks!
