I don't know how Ardor3D does lighting, I can't find any documentation. But one guess is that it maybe uses fixed-function lighting (GL_COLOR_MATERIAL is fixed-function). Then you must supply normals for each vertex, if not then you'd get the effect of material colors not being used, only the light color. So maybe normals are missing/wrong.
