There aren’t many varieties of E12 bulbs. They’re smaller, so they have a relatively low wattage of below 40W. Can You Use a B11 Bulb With a Bayonet Base?

The small E12 base isn’t as common as the larger E26. It’s limited to incandescent or decorative bulbs, which is why it’s named the candelabra bulb. On the other hand, E26 bases are suitable for everyday use. While base adapters can be lifesavers, we only recommend them as a last option, or for only one or two bulbs! The adapters can be bulky, thus ruining the beautiful shape of a B11 bulb.These bases are suitable for decorative light fixtures such as wall sconces, ceiling fans, and pendant lights. They are also used in appliance lightings like refrigerators and range hoods.

An E12 fitting is an Edison screw base type with a diameter of 12mm. It is also known as the Candelabra base, and in terms of size, it’s less than half of the standard E26 base. What is the Difference Between C7 and E12? The E11 and E12 base types are the most commonly used candelabra base types. Bulbs with these bases are ideal for small lamps, nightlights, bathroom mirrors, and mini chandeliers. E39 and E40 are other sets of bases you can use interchangeably. However, it is not a common practice to do so. That’s because the thread outside diameter differs by only one millimeter (0.04 inches), yet the pitch is slightly different. Therefore, it is more likely for an E40 cap to fit into an E39 holder rather than the other way around.B11 bulbs commonly have an E12 candelabra base, but might have a medium E26 base. Moreover, B11 bulbs might have a bayonet mount. These are the bases with the largest diameter. They are suitable for high-wattage bulbs like high-intensity discharge lamps, streetlights, reflector floodlights, and large decorative lamps.
