The model of the table lamp is done in Cinema 4d and rendered in Redshift with all the textures and materials created, ready to use right away with the same software.
Also in the Zip included a bump map for the glass part.You could paint something on top of it and have a different pattern.
The model is ready for Subdiv and has enough resolution for close-up renders.
Consider that Redshift changed color space from 3.0.49 and you would need that version or higher in order to have the same result.
Happy renders!
