This is the Tom Dixon Bell Lamp Collection in a quite hi-detailed version (with bulb, internal frame) ready to render in vray and corona (only Lamps, no scene).
All needed materials, textures and lights are included and easy to modify.
The Lamps come in three different distinct colors (chrome, copper, brass).

Who works with V-Ray version lower than 3.1, pay attention to materials section BRDF (Microfaset GTR (GGX)), if your version is older than 3.1 - this option will be empty and you have to choose: Blinn,Ward or Phong, depence on material.
