Realistic 3D lamp and low poly.
Object completely free for any use.

All my models are made in two versions.

High Poly: With 8258 polygons
Low Poly: with 391 polygons

Note: You must activate the option Screen Space Reflections and
then Refraction. then go to the glass material activate the screen space reflactions, set the transmission to 1000 and the refraction index to 0.980 so that the glass material works perfectly, and of course this can vary between software.

If you liked 3d don't forget to stop by our page here on turbosquid I'm working on several other 3d models for future additionals ;)
