12 volt light bulb socket enable light bulbs to be fitted to lamps or other light fixtures that are built with sockets of varying sizes. These adapters 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 12 volt light bulb socket. The lamps most commonly used in the hobby are single-ended, with a screw-type mounting 12 volt light bulb socket. The size of the lamp holders 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 lamp holder. The differences are small enough that the E40 lamp holder will work fine in the typical E39 lamp holder used in the U.S. Double-ended 150-watt lamps use the RSC (RX7s) 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. 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.

The E stands for Edison and the 26 and 27 refer to the diameter of the screw E27 Base Light Bulb. In some, but not all cases an E26 LED light bulbs have a slightly smaller voltage range to include only 100VAC to 130VAC where E27 LED lights will support up to 80VAC to 240VAC voltage range. This is not universal.

Prior to the renovation, a comprehensive grasp of these knowledge is very necessary. Today to all of us, in order to provide a reference for the decoration of the LED bulb: that is, LED spherical bulb, is used to replace the traditional incandescent lamp and U type energy-saving lamps, is currently the most widely used LED lamp.
