Posted this here as I felt it would get relevant attention here. now Im no novice as such but Im lost. My final render is different from my viewport render. the light is noticeably different, in my viewport render the light is “on” so to speak and in the final render its off and the objects in the scene are lighting up everything (computer monitors etc). what have I missed out here? :S

Hard to guess, any screenshots of both images or .blend?

Sounds like you have the ‘Color Management’ tickbox unselected.
Find it in the Blender Render / Render settings.

Also moved your thread to the correct forum.
