3ds Max :: Replacing A Mesh Object With A Light Source

If it is possible to replace objects in a scene with light objects. The normal replace function in the import menu will only replace normal mesh objects with other mesh objects. But if I try the same by replacing box objects in my scene with the light source object I saved in a separate max file, it says it doesn't find any objects in the max file with the same name despite it having the exact same name. (both objects in question have all lower case letters in the name)

I'm currently using Max 10 to render lightmaps for a first person shooter game and I use various scripts to get the game content into the scene. The game also provides object positions for glow objects which are in positions I intend to use for light sources. Normally I go through a long tedious process of cloning light objects and positioning roughly in the same area where the glow objects are. (objects I decide not to replace with the game's object meshes appear as standard box objects in max unless I convert them to mesh objects).

But I would like to create a set of light objects and do a batch replace on some objects already in the scene with my light objects. This would save me a lot of time. Is there a function max that can do this or is there a script that can do this?
