Collar on porcelain pull string ceiling light

I have to replace a pull-string ceiling light (porcelain) in an unfinished basement. The old one has a porcelain collar that screws around the outside of the bulb's metal socket, but none of the new ones I've seen in the store or on-line have it. The collar from the old one doesn't seem to fit into/onto the new fixture. Do I need the collar for any reason (e.g., to meet code)?

Thanks in advance for any information.

If I am understanding your question, you do not need a fixture with a collar. Old porcelain fixtures had this removable collar to allow certain bulb covers to be installed. New fixtures will not accept these old bulb covers, which I am not sure are even available any longer.

Buy a new porcelain or even plastic fixture and install it. I prefer plastic as they wont; break if you drop it while installing it or over tighten the screws. However, this is NOT an endorsement to over tighten the screws.

Bob, thanks for your quick reply! This is indeed an older light fixture (probably 30 years or so). I was concerned because the other 3 pull string fixtures in the basement had the same collar and I found an inspector's checklist online at: http://www.inspectusa.com/train/electrical_train.htm

that seemed to point out these collars. Item 8 under C. "General Wiring" is what had caught my eye.

I'll go ahead and replace the fixture with the newer style. Thanks again.
