If you're trying to import Poser's lights, then just be sure the "import lighting" box is checked on the Poser Scene Import window that pops up.  If you're trying to use C5's GI lighting, it's a render option you enable from the Render room.  It's on the rendering tab just below your raytracing settings.   Lots of options and sliders to fiddle with under global illumination. ;-)  If you like to look at a sample of GI lighting, go to the browser in the Assemble room and click on the scenes tab.  You'll see a collection of different sample scenes using various setups of Global Illumination.  Load them up and see what settings were used for each example.  Have fun exploraing!
