If you're referring to DirectX lights, you need to understand that they work by illuminating polygons where all three vertices of that polygon are contained within a light's radius.
It could be that you need to increase or reduce the LightRange of the light you created to get the right effect.
Alternatively, look at Quill3D. It does lightmapping and exports to B3D format. Might suit your requirements better?
