Light sockets « on: December 24, 2017, 12:23:45 AM » Author: Cole D.
I was wondering this awhile. Why do older light fixtures, like from the 60s/70s have brown plastic light sockets, whereas ones from the 90s or so and newer are porcelain. Also, why do older lamps have gold colored shells for the sockets, whereas more recent ones have dark brown/black plastic material. I know you can still get the metal shell replacement sockets but new lamps seem to be plastic.

Collect vintage incandescent and fluorescent fixtures. Also like HID lighting and streetlights.

The Brown stuff is Bakelite, thermosetting material made by compressing the part out of powder and then baking it. Modern Plastic sockets are made nostly of PBT (the White-ish ones), few of Phenolic thermosetting material (similar to Bakelite, but mostly clear Black), but for some reason most of the stuff coming from China have the Porcelain sockets and not the supposedly cheaper Plastic materials
