I was working with groups of lights and blender engine
is this done in blender render or cycles, btw it looks as if it is all just plastic. Some simple nodes should fix that up but that could be the effect your going for. Good job though, nice finished result on some of the renders!
The tests where made using the Internal Blender Engine, and without use of nodes with basic models, to see how the light groups affect glass, skin (subsurface scattering), etc.
And yes, in some cases the result was very good
