The only things that are in the ./eteks/sweethome3d/plugins directory are the advancedrendering.sh3p and the advancedrenderingmini.sh3p, nothing else.
The only thing that is in the ./eteks/sweethome3d/furniture directory is the fancy door that I recently added to the catalog.

Where do you get the incandescent lights? I can't find them anywhere. They seem to be the only thing that works.

P.S. I finally found the way to delete the basic lights.
