Yes and no. Unfortunately I don't have any of the sets you mention so I can't help you out there. If you want the scene to be lit using only an HDRI (which a least one of the products you mentioned has) then you need to crank up the intensity or adjust your tone mapping settings for Iray to "see" the light (something your eyes or a point and shoot digital camera does auto-magically). For the other lights in the sets, you will probably need to either adjust/increase their intensity (for mesh lights you do this in the surface settings under luminance).
Below is a quick sample render I did of the Fantasy Scene with a three point light setup (mesh lights). you can download my mesh lights freebie used for the render HERE.
Hope this helps!
Are the lights inside the structure? As Dustrider mentions, for photometric spots and point lights, try putting the luminous flux to 100000 for a start.
Iyou render just plain black or is there not enough light to really see stuff but there is something rendered?
some times plain black some times rarely any light and im trying to figure out how to do it
