Hello, I need to replace a burned out bulb by my bench. It’s a tear-shaped 40 watt LED. As you can see by the picture below, my old bulb has the same stem as the new one, but the new one (or ones, I tried others
in the pack) is not working : / Although these bulbs seem interchangeable, apparently they aren’t.

Can anyone shed any light on this issue? (pun wasn’t intended, but since it popped up, I’ll go with it : )

Thanks for your help …

I maintain an apartment complex, and ran into the same issue with some outdoor lights. As it turned out, the bases on the new ones weren’t actually making contact, They were too fat just above the threaded portion: looks like yours have the same problem. I had to take them back and find some with bases that matched the old ones exactly.

Good luck. Hope that sheds some light on the situation.

The bulb on the left (burned out one) has a “candelabra base” and you should be able to match it exactly at HD or Lowes. It’s also available in other wattages.

The CFL on the right is “supposed” to fit but as Bob said above you may have to search thru the pile to find one that doesn’t have the shoulder in the plastic where it meets the metal threaded part.

I had the same issue and just went with the old style.

It seems the standard is not precise enough, as I have the same problem with similar bulbs (E14 socket) on a pendant made in Italy.

I ran into the same problem with these bulbs when trying to change to some led bulbs on some ceiling fans. Obviously they manufacturers have some changes to make

Throw flood lights into the mix also. As an electrician, it’s becoming a pain to find led/cfl lamps that will work for a particular application. If it has a close fitting shroud/reflector around the lamp holder, you might want to put a close eye on it.
