Doesn't have to be a material effect. Just put a lamp there and make it subtle. –  iKlsR Apr 30 at 5:26

Material

You can use a Gradient node with Object mapping to make a spherical gradient based on the location of the object origin:

The mapping node is just used to scale the texture up a bit.
The multiply node controls the overall strength.

Note that scaling in object mode will stretch the texture accordingly, however applying the scale or scaling in edit mode will not.

AO

It's also possible that your reference image was created with a very heavy Ambient Occlusion effect.

To achieve this:

  1. Enable AO in Properties > Render layers > Passes

  2. Adjust it and multiply it with the combined pass in the compositor:

Combined with the gradient:

That works great but how would you spread out the light using the material method? Scaling up has no effect on the light. –  Qwertie ϟ Apr 30 at 11:32
    
You can manually compensate with the mapping node scale, but it should be stretching automatically.. Are you scaling in object mode? –  gandalf3 Apr 30 at 18:15
    
I was scaling in edit mode –  Qwertie ϟ May 1 at 8:15
