Here are a couple of hi-quality 3d models: a floor lamp and a table lamp, inspired by the 1965 work of Armando Ronca, italian architect and designer (https://en.wikipedia.org/wiki/Armando_Ronca), for the Eurotel Hotels in Meran.

Both models have proper real world scale and are ready to use for your visualization.

Objects are grouped in collections; materials are original and procedural (no textures) and easily editable.

FILES: BOTH MODELS in a .blend file and two separate .fbx
