The Source Filament object gives a nice starting point to quite easily make an approximate tungsten filament light source model.  You are required to give the inputs of length of the coil, radius of the coil, and the number of turns in the length of the coil, along with the other standard properties of position and orientation and the number of rays to launch.

Using this Source Filament object is very quick and easy to set it up and launch your rays, but notice that they all emanate from a line source.  This is probably OK for your initial system setup and design layout, but you may need to model the extended area of a typical tungsten filament source to fully characterize your illumination system.

To build a more detailed source is quick and easy using the Source Object.
