I've tried your suggestions and using ambient in each face of the stained glass works quite well, but I've also tried a spotlight with one of the textures on it and that makes no difference whatsoever, so obviously there's something I'm not doing right with that.

I've no idea how to make a spotlight 'wide' or what to do with it otherwise.

Here's what I've got so far:
