That looks awesome!
Thanks for your help, I'm relatively new to V-Ray for SU, so this will help with my experimenting 😄
I googled how to make lights in Corel and found a pretty decent tutorial, so all smiles for the near future!

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..
