What is a Type F power plug? And an E27 Edison Screw? There are many types of power plugs, outlets & lightbulb sockets out there and depending on your country or electrical appliance, you will need one or another. For example, if you live in the United Kingdom and your home is equipped with Type G outlets (or sockets), you will not be able to use a TV that has an F type plug, unless you also use an adapter.
Power plugs and outlets (or sockets)
There are currently 15 types of electrical outlet plugs in use today, each of which has been assigned a letter by the US Department of Commerce International Trade Administration (ITA), starting with A and moving through the alphabet. These letters are completely arbitrary: they don’t actually mandate anything. This scheme was adopted by the European Union and became a world standard.
On this page HERE, you will find detailed explanations about all 15 of them. And HERE you will find a detailed list of the countries of the world with their respective plug and outlet types, voltage and frequency. You can click HERE for a global map showing the spread of the different plug types used around the world.
There is no secret in the fact that a lightbulb will not light up without some kind of electric power. So firs we have to fit it in the appropiate (and working) lightbulb socket.
There are many different standards for these lightbulb sockets. A general coding system is a letter or abbreviation followed by a number. The most common type of sockets for mains electricity are Edison Screws, used in continental Europe and North America, while bayonet mounts dominate in the Commonwealth countries and in the automotive industry. Fluorescent lamps require a different, typically four-pin design.
You can find HERE a comprehensive list of (almost) all of them.
