It’s hard to answer that in general. It depends on the room size, height and the feel you wish to crate. As a rule of thumb, you can say one lamp per 60 / 80cm table. If the room is 2.5m high, then the smaller models are more likely. If the ceilings are 3m or higher, then the XL versions are more likely. With AION XL, one lamp per meter is sufficient. Models like ENA or TEIA turn the table into a light island with reflector lamps. It is rather cozy. AION emits more light upwards and illuminates the room more.
