Product Information

Edison designed a screw base for use in his incandescent bulbs. This patented design became incredibly popular, leading to the widespread use of “E” bases for light bulbs worldwide.

Bi-pin bases have a unique coding system. Usually, their codes start with the letter “G.” The letter “G” is an acronym for glass, the material used to make traditional light bulbs. 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 Bases In that case, it might have a higher voltage than the standard 120 volts. What Will Happen If I Choose the Wrong Base Size? It can also cause injury to you or your property. Therefore, choosing the right light bulb base size is crucial. Final Thoughts Bi-pin bases are also popular with energy-saving fluorescent bulbs since they require less electricity than their traditional incandescent counterparts.Mogul bulb bases are cast porcelain with good thermal conductivity and the ability to withstand high temperatures. Additionally, the threads have a coating meant to prevent corrosion. For color temperature, we recommend a CCT of 2400K. Why? Most E12 bulbs are designed to mimic the appearance of candlelight. A candle flame has a CCT of 1900K, which appears much warmer than the filament of an incandescent bulb.

Light bulbs come in many shapes, sizes, and wattages. Some of them look very similar – such as the E12 and E14 bulbs – and may seem interchangeable. 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. Jenkins, John. "Early Incandescent lamps". SPARK Museum of Electrical Invention . Retrieved 7 September 2020. E12 LED Bulbs: E12 bulbs are also known as “Candelabra Base” (candelabra base) because of its shape like the base of a candle. It is a small lamp holder, about 12mm in diameter. E12 bulbs are often used in smaller lighting fixtures such as chandeliers, wall sconces, and table lamps.

Therefore, if you’re using a lamp with an E27 base, you can easily replace it with an E26 without affecting the functionality and appearance of the light. E14 LED Bulbs: E14 bulbs are also known as “Small Edison Screw” because of the similar thread size to regular Edison screw bulbs. The diameter of an E14 bulb is about 14 mm, which is slightly larger than that of an E12 bulb. E14 bulbs are typically used in medium-sized lighting fixtures such as chandeliers, wall sconces, and floor lamps. Most decorative light bulbs in the U.S. are both B11 / E12 bulbs. For this reason, you might find these light bulbs labeled only as B11. They are commonly used for general lighting in standard light fixtures, such as ceiling lights, lamps, can lights, outdoor spotlight and flood light fixtures, and vanity lights. Also known as the Candelabra Edison screw (120V), E12 bulbs may also be used in Christmas decorations and boats.

These bulbs come with a 14-mm diameter screw, just as the name suggests, making the bulb about the same width as your little finger. The most significant difference between this type and B15 is their size. Both have identical pins and slot mechanisms, so they use the same push-and-twist mounting approach mechanism. As for the screw fittings, they will always start with the letter E, which stands for Edison Screw. So, unless you’re in Europe, it’s safe to assume that a B11 light bulb has an E12 base.

All three major designs were patented. Edison himself filed his applications in 1881 [1] and 1890. [3] In response to Edison's patent, Reginald Fessenden invented the bi-pin connector for the 1893 World's Fair. The E14 intermediate base is the most common option in this category. Its diameter of 14 millimeters makes it larger than candelabra bases but smaller than the standard base size.
