Intermediate Screw Base (E17) Bulbs are sometimes called Intermediate Edison Screw (IES), “E” stands for “Edison” and “17” indicates the diameter in millimeters as measured across the peaks of the thread on the base index".

In North America and continental Europe, Edison screws took the place of other types of bases for general lighting.

Ideal replacement for traditional fluorescent 2D bulbs. Compatible with existing magnetic ballast with no need to rewire. Starter supplied. When you buy light bulbs for a home with C-type outlets, make sure they can handle the higher operating voltages – otherwise, you risk having them blow out or catch fire if used in such fixtures. The three most often used bases in the United States of America for traditional lighting are the E12 (candelabra), the E26 (medium), and the E39 (mogul). Light Bulb Base Sizes Chart For example, a T10 wedge base is commonly used in automotive taillights, while a T15 wedge base is used in some turn signal and brake light applications. A lowercase "q" at the end of the designation indicates that it is a quad-pin base, with two bi-pin pairs. These are used with compact fluorescent tubes that plug into a light fixture that has a permanent ballast.The screw-in bases, Edison E26 and the larger-sized E27 are usually interchangeable. The medium-sized B22d is also often used with a bayonet fitting. Bulbs with E12 bases are commonly used for decorative applications, such as chandeliers, wall sconces, Christmas lights, restaurant pendant lights, ornamental lights, residential or commercial string lights, and night lights. Many bulbs with these bases are designed to mimic the look of a candle flame.

The biggest light bulb base is one with a diameter between 40mm and 50 mm (E39 or E40). Which is the smallest light bulb base? This article discusses the different types of light bulb bases. It broadly covers what the different light or lamp bases mean, why different lamp bases are used for different lighting applications, and where those light bulb bases are used. Additionally, it provides a light bulb base sizes chart in shareable image format. Light Bulb Base Sizes Halogen various wattage (e.g. 50 W/100 W), various voltage (e.g. 12/24 V). Common for task lighting, landscape lighting. E26 is the size of most light bulbs used in the U.S. It’s referred to as having a “medium” or “standard” base.The large E39 “mogul” base is used on street lights, and high-wattage lamps (such as a 100/200/300 Watt three-way). Chances are you won’t have a need for these guys.

The name “Exx” is made up of the letters “E” for “Edison” and “xx” for the millimeter diameter measured across the peaks of the thread on the base (male). As the name suggests, the fitting is 12 millimeters in diameter size and is often deemed the Candelabra Edison Screw (CES). It is the home of C7-sized lamps, so if you bought a C7 lamp before, it utilized the E12 fitting. Like candelabra bulbs with E12 bases, bulbs with E17 bases are used for decorative applications, such as chandeliers, wall sconces, Christmas lights, restaurant pendant lights, ornamental lights, and sign or marquee lights. Bulbs with these bases are commonly used for appliance lights, such as microwave lights, refrigerator lights, and range hood lights. They’re also found in ceiling fan light fixtures. There are dozens of different light bulb bases. The most common is the Edison screw base, which may be found on most incandescent bulbs and many halogens, compact fluorescents, HIDs, and now LED lights. Edison Screw BasesThe Edison screw (ES) is a type of light bulb base that is universally used with electric light bulbs. Thomas Edison invented it and patented it in 1881. The bi-pin base was invented by Reginald Fessenden for the 1893 World's Fair in Chicago. [ citation needed] After Westinghouse won the contract to wire and illuminate the first electrified fair with AC instead of arch-rival Thomas Edison's DC, Edison and his General Electric company refused to allow his patented Edison screw-base bulbs to be used. Westinghouse overcame this by developing the bi-pin base for use at the fair. An incandescent electric lamp with a bi-pin base was patented by the Westinghouse (G. Westinghouse, Jr.) in 1895. [1] [ non-primary source needed] Types [ edit ] Illustration E39 is known as the large base or mogul base. Its typically what is used on older metal halides and high pressure sodium from 100 watts and up. The E is for Edison screw base and the 39 is 39 mm across. Larger than the standard E26 or 26 mm across. Light bulb base sizes vary with the type of bulb and application. The base of a light bulb also contains information about the bulb type, and wattage, which may also indicate the maximum overall length of the bulb. E11 and E12 are not interchangeable because of their different size. Does the Bulbs Base affect voltage and performance?

The letter “E” in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical “26” refers to its diameter in millimeters (approximately 1 inch).However, light bulb bases are not standardized. This is to prevent dangerous light bulbs from being used in light fixtures that aren’t designed for them. Wedge bases are designed to be easy to use and provide a secure connection. They can be found in a variety of sizes and configurations, depending on the specific application. In addition to automotive lighting, wedge bases are also used in other applications such as outdoor lighting, commercial lighting, and theatrical lighting. They are a popular choice because of their simplicity, reliability, and versatility. COMPACT FLUORESCENT PLUG IN BASES The most common type of base is the E type. The E stands for Edison and indicates that the base is a screw type. The size is a simple millimeter measurement of the width.
