Vray render to light element

This is news to me (though you industry buffs probably knew this already).

I suppose since I've posted this thread I may as well use it to ask a question:

What would be the best way to create a semi-transparent material with a light behind it? Something like this, with a hotspot in the center:

I'm using vray and for some reason putting a VrayLight behind a material with 50% refraction isn't working. So I was going to unwrap the object and use PS to create a lumination map, then use a standard material with self illumination. But I've got tonnes of these to do and if there's a better way, I'm all ears.

Create translucent colored box, put a light in it.

I find light select good to enhance lights in post but otherwise, just make it how you see it, cant go wrong. For instance, I see some awesome archviz renders, but the lights are just white areas of light instead of a bulb generating light, etc. Makes a big difference (Look at the light above the kids head, looks good because of the light displacement in the glass)

I tried that but it was giving strange results (only highlighting the corners and not the center).

I did come up with a great cheat though, you can use a gradient map on the diffuse (set on box) and instance it to the self illumination and it gives pretty nice results.
