Well you won’t, it’s not in there. Generic tungsten lanterns are just patched as Dimmer, they don’t need any other information for the console.
The same way you’ll never find ETC Source 4 in there or CCT Minuette or Strand Prelude. The console doesn’t talk to these types of fixture over DMX, it talks to a dimmer. The console couldn’t care less what type of generic lantern you plug into that dimmer output, it can only dim it.
If the fixture were more complex, say an LED, then the console needs to know which channel is red, which green, etc, which channel is the strobe. If it’s a mover then it needs to know the pan and tilt controls etc. In that case you have to find the correct fixture definition (and mode) so the FLX knows how to control all of the parameters of that light. None of this is required for a generic light which can just go on or off.
If you were building a design in Capture then you would look up Strand Quartet PC in their library so that Capture knows what beam angle the light supports, if it has a barn door, what gel colour is in it, what it’s luminous intensity is compared to other lights in the rig, so it can model it. But from the FLX point of view it’s just a dimmer channel.
