I did a similar thing using a sky_sphere. What I found is that the brightness of
the object has to be adjusted relative to it's size, so a smaller lightsource
needs to be brighter to have the same effect on the scene (obvious if you think
about it!). Though I prefer using a light_source, as that way you can have
specular highlights and photons.
