E27 Screw Base

E27 Screw Base enable light bulbs to be fitted to lamps or other light fixtures that are built with sockets of varying sizes. These E27 Screw Base essentially work as interim sockets that, once screwed into a fixture’s own socket, allow for such fixtures to use either larger or smaller light bulbs than what they have been built to hold.

After the specific lamp has been selected, the next step is to check the lamp’s mounting base. The lamps most commonly used in the hobby are single-ended, with a screw-type mounting base. The size of the base and the threads is also described by a code, although names are more commonly used. For example, Base – E39 is commonly called a mogul base.

European lamps also have a mogul base, but it is slightly different from the E-39 and is called E40. The differences are small enough that the E40 lamp holder lamps will work fine in the typical E39 mogul base used in the U.S. Double-ended 150-watt lamps use the RSC R7s base, while the 250-watt double-ended lamps use the Fc2 base. Figure 3 shows the various shapes and configurations of lamps and bases, along with the restrictions on their various operating positions.

Light bulbs have become common place in everyone’s home since Edison invented the first one in xxx. Unfortunately until more recent developments in LED technology, the traditional light bulb has been little more than an energy hungry, light emitting heat unit. Consuming 40-100 watts of energy every time you flick the switch.
If a lamp currently has an unfavorable socket size, an adapter can easily change the socket to accept another bulb size. Where a lamp has an uncommon size socket (intermediate or French) adapting the socket will allow you to use more common candelabra size bulbs.
