I used them to extend the sockets in my outdoor spotlight so I could use wide base smart sockets that couldn't plug directly into the recessed sockets on the light. They worked great and at a great price! I originally (mistakenly) bought longer ones (6.5cm/2.56" extension adapter, 200W max bulb extension) but they were much longer than needed for my application. I will not be returning them given the cheap price of these adapters. Maybe they can be used for another project.
