Bulb holder converter enable light bulbs to be fitted to lamps or other light fixtures that are built with light bulb holder of varying sizes. These light socket adapters essentially work as interim light bulb holder that, once screwed into a fixture's own light bulb socket, allow for such fixtures to use either larger or smaller light bulbs than what they have been built to hold.
Bulb holder converter Type is a catalog of light bulbs whereby a bulb can be found by the type of base that the light bulb has. Since light bulbs have different base types, eg: E14 to E27 adapter, B22 to E27 adapter, E27 to B22 adapter and so on, if you know the base of the bulb you are looking for, we can omit the bulbs that do not have that lamp base type. There are three main categories for led sockets types; Insert and Twist, Push-in/Plug-in and Screw In.
