Quote - Using a prop insteed of adding parameters to a poserlight allows any geometry you like as a lightsource. This may be new to Poser uses, but maybe you can imagine what is possible with something like that. 

That sounds great to me, you can have light bulbs emitting light, windows or screen doors acting as area lights.
