    Mesh lights... if you go to the tutorial I linked to in the second post, those are mesh lights. The light is coming "from the mesh", so you could make any mesk an emissive.

    If you use a mesh light, you can also make it invisible ba giving it a very low value in cutout opacity (like, 0.000001) and it will still give you light.

    I like the Iray Ghost Light kits for those times where I need some additional light but don't want to mess with spotlights or playing with the emissive settings on scene items.

    I know I could make my own, but I like having the quick settings that the kits provide available. 

    Also, SickleYield has some great tutorials on Iray lighting and tone-mapping. I've been working with the three-point lighting one lately and it produces great results.

    thank you. i have done what you say and it has worked well. is there a way to get an object to look completely the same while still emitting light? i have not figured out how to do this yet. EITHER, i get the solid color (white) or i turn the opacity down to hide the null or object. but can i make a mirror let say, both reflect as it normally would visually but also have it emit light?

    There's a thread on how to make ghost lights (invisible to the camera but still emits light). It's kind of an involved process, but it works and works well. https://www.daz3d.com/forums/discussion/62526/quick-howto-making-mesh-lights-invisible-to-the-camera (Method #3 that Tobor describes.)

    I'm not sure if it's caused by a bug or just an undocumented feature, but ghost lights can behave in unexpected ways, so just be patient and experiment. To use it on your mirror, you can place the ghost light directly in front of the glass.

    Edit: Also, just make sure the ghost light is not two sided and that it's emmiting light away from the mirror.

    what is the best ratio of glossy roughness to weight for this kind of result?

    My Art Studio thread has a list of references from the past five years, alphabetically, in the second post through a couple after that. I did an Iray tutorial which is very specific, (Wanna Render?) and a lot of light tutorials are in that post.  The Wanna Render? tells you about the Exposure Value, ISO, crush blacks, burn highlights- it's very comprehensive to make it easy. (training was my professional field. I baby-step you.)  I recommend Ghost Lights for soft fill lights on hard to light indoor scenes, and I use the BOSS and Pro-Studio lights for showcasing products like characters (portraits.) 

    DA Real World Lighting is good for outdoors- Gallery.

    This one had Ghost Lights added, shining from over her shoulder, and from the left onto her face/torso. Gallery  It's a nice, soft fill.

    Here's the Pro-Studio lights in action.  Gallery

    This one was Painter's Lights, which give warmer/colder looks like Old Masters. Gallery 

    Hope this helps. :)

    By the way... there's a live tutorial/Webinar for lighting this wekend. The webinars are usually very informative, and the best thing is that you can ask questions directly when you don't understand something, or need it to be re-shown. I can only recommend it.
