Light bulbs draw their power from wires via electrical/mechanical connections.

There are many different standards for these sockets, created by de facto and by various standards bodies.

Some types of socket are listed here.

The Bi-pin base has several advantages

Bulb orientation is fixed so filament will always be in the focal plane. Filament configurations such as the C13D (coiled, zig-zagged) emit far more light perpendicular to the zig zag than parallel to it.
Sockets

Mogul Bi-pin is used with searchlights, film & stage lighting fixtures 1000 watts or larger. Incandescent, halogen and HMI light sources use this design.
Medium Bi-pin is used with film & stage lighting fixtures between 250 and 1000 watts (the development of the T14 base up to horizon design for ellipsoidal spotlights was one of the most important innovations of the mid 20th century)
Mini Bi-pin has several variations for MR11 and MR16 depending on pin diameter and spacing.
