How to move lights away from the wall.

Hi there.
I am fairly new to Vray for SU and am having trouble with the lights.
The first issue is that even though the lights are centered in the light fitting, the light renders as if it is against the wall (see image).

The second is I cant get rid of the dark grey background unless I turn up the exposure on the camera, but this makes EVERYTHING over exposed (see the same image)

Thanks in advance for any advice!

So I solved the second problem of the dark background by adjusting the BG Colour and intensity settings, but still stuck on the lights. The problem with creating an emmissive material and applying it to a tube shape is that you can see where the tube ends, and I would like the light to kind of fade away as in the image if possible..
