E-Type Speciality Lamp Sockets

E10 and E11 lamp sockets are types of electrical connectors commonly used for small bulbs, such as incandescent and LED bulbs. They are characterized by a threaded base with a small diameter and are designed to fit into matching sockets in light fixtures.

The E10 socket has a diameter of 10mm, while the E11 socket has a diameter of 11mm. They both have a threaded metal base, which allows the socket to be screwed into the fixture, and two or more metal contacts inside the socket that make contact with the electrical contacts on the bulb.
