Darkelegance says the point lights don't seem to do much, and I would have agreed - at one time. Now they are amongst my favourite tools. They feature in my image Carleena and Harry avoiding the Beast (https://market.renderosity.com/mod/gallery/index.php?image_id=2608381). I think I used Iray in DS 4.8 but possibly not, in which case it will have been 3Delight. Iray is temperamental on my computer but fantastic when I get it to work. The torches and Harry are all lit with point lights, using variations of colour, intensity and scale. 

If you use Iray, you can expect long times for renders. 3Delight is pretty quick I find.
