Rendering pitch black

[Anonymous]

So. 

I have two issues.

1. as you can see my area light has super high intensity, and even with my "use all lights" turned on with number 7 key, its not doing anything on viewport. 
2. when I hit render on ARnold, it just renders pitch black screen and when I come back to viewport, the background turns pitch black like the first image.

What am I doing wrong here? I cannot find any issues related to this on the forum

Hi!

Please provide a scene-file.

Click the AreaLight's IlluminatesByDefault switch, maybe?
