    Make sure you have the head lamp turned off in renderoring..  That's usually the case when I'm trying to figure out why things aren't as dark as i want it to be :p

    Go to your environment tab in your render settings and change the lighting to scene only. Then make sure you turn the headlight off on your camera(s). Although, from reading several posts, this is not the best way to light a dark scene. It will be slow and probably create alot of grain. What ive read is that you should light the scene brightly and then postwork it in photoshop or gimp to bring tht light levels down to a good, scary darkness level.

    While I'm not an expert at Iray yet, I would have to agree on slow and grainy part, but not the rest.  To get rid of the grainy, up the quality and force Iray to render longer.  Yes, slower still, but I think it is better this way than messing with it in post.  Changing the Tone Mapping settings, to get the look you want, is the better way of handling darker scenes.  Definitely turn off the headlamp and choose Scene Only under Render Settings Tab.  You can do an awful lot with Tone Mapping!

    Ive been using Tonal Rage quite a bit but it never occured to me that it would also help in this instance. Ill definetely have to try that.

    here's where the headlight controls are.

    i believe you have to create a camera before you can access the camera tab settings.

    I don't know about the tone mapping but you can turn the headlamp on and off with Control+L.

    In the "surfaces" tab make sure you have the candle's flame selected. Then under "smart content">>"shaders" find this little guy and double click it:

    Then go back to the surfaces tab and scroll down until you come to these settings:

    You can then adjust the flame's light by adjusting those settings. The first thing I usually do with these settings is change the "Luminance Units" from "cd/m^2" to "W". You can then make the candle light brighter by sliding the "Luminance" dial to the right. You can change the light's color by changing the "Emission Color". Often times candle light is a bit yellow, so I'd probably change that Emission Color a slight yellowish color. 

    I hope that helps! :)

    tone mapping controls are here.

    basically, changing the tone mapping controls is like changing the settings of a film or digital camera. 

    so a lot of these settings can affect the way your iray light source looks in your render, and the way it lights up your scene. 

    the daz studio documentation for the panel is here:  http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/interface/panes/render_settings/engine/nvidia_iray/tone_mapping/start

    If a flame or fire prop is just planes emissive shading doesn't work vey well as it can only cast light perpendicular to the planes.  For candle flames the tear prop from the free EmotiGuy looks and works well just scale it a little on the y-axis.
