A light works in one socket but not another. But the socket is functioning

Question

I am using a cord and light recommended by Ikea: the Sunneby cord and Molnart E26 LED bulb.

But after installing it, the light wouldn't turn on. What's happening here?

1. The Molnart E26 works in other light sockets — so it's not the light

2. Other standard E26 bulbs work in the Sunneby socket — so it's not the socket

3. Other E26 bulbs that are like the Molnart (fake incandescent LED effect bulb) do NOT work — so maybe a specific wattage or type of bulb?

I've also pulled out the pad inside the socket out a bit to ensure it makes contact, no change.

Answer 1

The socket you are trying to screw your lamp into is an Edison base socket, which makes contact at the base of the lamp and passes though the lamp and returns through the outer metal ring of the socket. The contact at the base of the lamp sometimes does not make good contact with the base of the socket.

Sometimes you can use a pair of needle nose pliers and pull that small piece of metal up in order to make sure that it is making proper contact with your new lamp.

Do I need to mention that the power must be off while you are working on the socket?

Be safe and good luck.
