Adapter socket from E27 to GU10
Sometimes you buy a new light, and when you connect it to your home, it appears that you have not bought the right size socket. Of course, you can choose to return the lamp and buy another one instead, but you can also fix it by adding an adapter. This allows the new lamp to be placed in the existing socket.
Adapter from E27 to GU10
This adapter converts a GU10 socket to an E27 socket. The lamp you turn in here must therefore have a GU10 socket, and it will then fit into a fixture with an E27 socket.
