Type of Light Bulb Base & Socket

The solder at the bottom of a 3-way light bulb base is divided into two voltage contact points by a plastic ring. Light bulb base to satisfy industry standards when said light bulb base is fully inserted into said adapter socket. Your standard light bulb base is considered an E26 or E27 and the LED lights are compatible with your light bulb socket.

Edison light bulb base is the standard incandescent size also known as E26 or medium screw base. Developed by Thomas Edison and licensed by Mazda in 1909, the Edison screw (ES) light bulb base is one of the two most common light fittings. However, E27 Light Bulb Base are rated for 220V; therefore, the voltage compatibility of bulb and light fixture must be checked. If an old light bulb base is found then the outside light circuit should be turned off and the bulb base should be carefully extracted.

Energy Efficient Lighting

Electric lighting burns up to 25% of the average home energy budget. The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself. Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs have revolutionized energy-efficient lighting.

CFLs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks similar to the common incandescent bulbs – not like the fluorescent lighting we associate with factories and schools. LEDs are small, very efficient solid bulbs.

New LED bulbs are grouped in clusters with diffuser lenses which have broadened the applications for LED use in the home. LED technology is advancing rapidly, with many new bulb styles available. Initially more expensive than CFLs, LEDs bring more value since they last longer. Also, the price of LED bulbs is going down each year as the manufacturing technology continues to improve.

LEDs (Light Emitting Diodes) are solid light bulbs which are extremely energy-efficient. When first developed, LEDs were limited to single-bulb use in applications such as instrument panels, electronics, pen lights and, more recently, strings of indoor and outdoor Christmas lights. See more here.

The center pole on the light bulb base is the DC positive terminal and the outer threaded part of the light bulb base is the DC negative.

Types of Light Bulb Bases

Once you know the shape of the LED bulb you’re looking to replace the next area of focus is identifying the base or socket.  This is very important since buying a bulb with the wrong base will mean that it won’t fit in the lamp or fixture.  LED light bulb bases fall into three main categories.

1) Edison

Edison bases LED bulbs are the most popular especially when looking to replace household light bulbs.  The different Edison bases are labelled with an E followed by a number that indicates the width of the base in millimeters.  There are names given to several of these bases:

E12 = Candelabra base      E14 = Small Edison Screw base

E17 = Intermediate base   E26 = Medium base  E39 = Mogul base

2) Bi-Pin

Bi-pin bases are denoted with a G followed by a number which indicates the width of the space between the pins.  Some of the most popular bi-pin bases are GU5.3 and GU10 which are found with MR16 LED bulbs.  The GU5.3 bi-pin base just plugs into the socket while GU10, as well as GU24 base LED bulbs twist and lock into place.

An internal folded-spring center contact 30 within the adapter socket 38 is configured to make electrical contact with the center contact of a light bulb base when the light bulb base is fully inserted into the adapter socket.

A Guide To Understanding Modern Light Bulbs: Base Types

As if there wasn’t enough to consider when it comes to picking out the right light bulb, being sure that you have the correct base type and size is yet another factor in your decision. Thankfully, this is probably the most straightforward of all the variables when it comes to purchasing a light bulb. To help you understand the four most common base types, we’ve come up with the following guide.

Modern Light Bulbs: Base Types

These are the four most common light bulb bases that you’ll encounter around your home:

  • Medium Screw Base (E26 are common in the U.S., E27 in Europe. E is for “Edison”, by the way)
  • Candelabra
  • GU
  • Bi-Pin

As you may have guessed, some types of light bulb shapes will often be paired with a certain type of light bulb base. This is because some styles and shapes of light bulb are designed with a specific use in mind, which will require that a certain type of light bulb base be used in order for the light bulb to work properly.

Light Bulb Base Is Important

Light bulb base can be modified so that the bulb can be inserted and secured, or released and removed, with a minimum of turning. The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass. When the rubber seals on the light bulb socket are either worn out or strangely shaped, or it might not even function properly.

A LED light bulb is a solid-state lighting (SSL) device that fits in standard screw-in connections but uses LEDs (light-emitting diodes) to produce light.   A light bulb that does not last very long can indicate that either the wattage of the bulb you are using is incorrect or that the light bulb socket is loose. Make sure the connectors and the courtesy light bulb socket are plugged in properly, and the rod is connected properly. call us here: (951) 805-1262.
