Question: Is the socket plastic or porcelain
Document: This is a fine base, but it is a bit larger than the older ones--so you may have to make a bracket to connect the lamp to the new socket. Otherwise, as advertised.
Had to make modifications to the original hardware in order to make this base socket work. The supplied installation bracket was also different from the original and could not be used. When installed the light switch does not line up with the hole in the lamp housing. I had to modify the original bracket by cutting aprox. 3/16&#34; off the bottom to make the switch hole line up with the lamp hole. If you are very handy and have the right tools this will work otherwise stay away!
THIS IS FOR A BIG BASE BULB,LIGHT FOR A BIG ROOM. THE BULBS LAST A LONG TIME. THE ONE I HAD WAS REALLY OLD, I AM GLAD I FOUND A REPLACEMENT. I REALLY LIKE THE FLOOR LAMP. THIS NEW REPLACEMENT SHOULD LAST 20 YEARS OR LONGER, THANK YOU SO MUCH. ROBERT
I was so grateful to find this product because I had a lamp from my grandmother that was no longer safe to use. Since I really wanted to be able to use the odd-sized bulbs, I hadn't been able to rewire it. My husband fixed the lamp in fifteen minutes as soon as the product arrived. Now I can enjoy my lamp and the bright light it gives.
I don't know if the packageing was not adequate  or what. I ordered two of these and one was missing a part and the other was badly chipped. However, I did get them attached to my lamps and they work except the little knob that turns the bulb on or off is extremely hard to turn. Its little ridges are sharp and it hurts my fingers. Altogether, they work but I am not happy with the condition of this product.
Answer: yes
