Changes:

1.1: (just my ocd update)
-cleaned out some unused images from the archive
-resized screenshot

***

The lightbulb has been fixed to cast shadows. The point of emittance was changed.

This is a simple version of a different mod, its for everyone.

Please check my other mod and it's forum for technical info.

The other mod shows problems with shadows and lighting, either from bugs or simply lack of knowledge about new formats.
If you interested in modding not just using the mod you should check it out.
Useful input would be appreciated.

Thanks for fo4edit and nifskope to their respective developers!!
