That file isn't the same anymore. I'm always trying new things.
The spheres that give off light - Just make them in object mode
What ever color you want
Ambient - .3
diffuse - .7
Specular - 3 (not .3)
Emissive - 1 (This is only useful if you don't use attributes; and don't forget to set to same color as Diffuse)
Rough - 1000
Brilliance - 1
Trans - .2
Attributes - Class - Dielectric
IOR - 1.04
In the scene mode make the lights the same color as the sphere and move them inside the sphere - Set the lights to Local(without shadows turned on in advanced setting)
Lighting - Global Intensity - 3
Ambient Intensity - 0
The object in the center has a spot light over it with shadows turn on in the advanced settings.
