Hope it can help you.

Thanks for the links to posts about "Ceiling downlight" and "How to create a down light embedded in the ceiling", VeroniQ.
Interesting reading, but is not an answer to my problem.

What I want is to have my own spotlight model (see picture) attached/binded/included with a light source, so the light power can be controlled. A new furniture/light exactly as in the category "Lights". But saved in my own library.
It is easy to do this in a scene, grouping the light source to the furniture/model/spotlight, but I want to have this "self lighting furniture" to be in a library so I can drag it into new scenes. I know we can copy and paste objects between open files, but this is still not what I aim at.

This is my spotlight (without a light source):


Your help is greatly appreciated!

Best regards,
Lars
