Thank you soo much for your big Support!
Because of it, i reworked the entire Product.

I cleaned up lose Edges, N-Gons etc and i gave every Lamp a new packed UV-Map and it's own Texture Set created with Substance Painter.
Also i add a little Oil-Bowl Setup and a more realistic Bowl Holder which can move by yourself anytime.
And i did other small changes to all Lamps.
