The Difference Between B10 and E12 Light Fixtures

Lighting plays a huge role in your home. Most people don’t realize just how big a role it plays. Dark lighting or bright lights can change the entire look of a room. It can also make areas feel more inviting.

Combine this with the ever-increasing cost of electricity, and you can likely already start to see how important lights are.

Obtaining a basic grasp of common household bulb shapes, sizes, and styles can go a long way to helping you save a few on electrical consumption. Every light bulb has its specific identifying characteristics. Most are represented by a letter or series of letters and a number.

These numbers are commonly referred to in the lighting industry as bulb codes. Learning these numbers will tell you a lot about your bulbs. Some numbers and letters might indicate the shape, while others indicate size and intensity.

Sometimes they can indicate the size of the bulb or a combination of the aforementioned.

Simply put, knowing, and understanding these numbers will be key to your next successful lighting buy. Of all the available choices today, two of the most popular chandelier bulbs are the B10 and E12. Are b10 and e12 bulbs interchangeable? Are b10 and e12 the same? These are all things you are going to learn below and more.

Are B10 and E12 The Same?

No, B10 and E12 bulbs are not the same. B10 describes the bulb’s shape whereas E12 describes the bulb’s base

You can likely already tell by the names b10 and e12 that these are not the same bulbs. As a matter of fact, the b and e are used to describe an entirely different aspect of the bulb. These are bulb codes with specific meaning.

For instance, the b describes the shape of the bulb, whereas the E refers to the base of the bulb.

These bulbs have a torpedo shape and are more commonly used in decorative scenarios. This unique design gives them a candle-like appearance.

These types of bulbs are similar in shape and size to that of the C and CA series bulbs. The C and CA bulbs do, however, give off more of a candle-like appearance.

b10 vs e12

So, when it comes to b10 vs e12, you can see that these numbers represent different aspects of the bulb. As was mentioned, the b refers to the shape of the bulb, but the E is used to describe the base of the bulb. The E base is 12 millimeters in diameter but can be available in other sizes as well.

One of the most utilized bulbs today is the A series bulb with an E series base. The A would represent the shape and the E would define the body of the bulb. It wouldn’t be unheard of to have a B series bulb with an E series base.

Understanding E12 Bulb Style

Each lightbulb is different in many ways. They may have unique shapes, tones, or brightness levels. Suffice to say, it can be difficult to find the perfect lightbulb for your chandelier, candelabra, or ceiling fan. Although it seems overly complicated, it doesn’t have to be.

First, you should know that E12 is used to describe bulbs with the Candelabra Edison screw design. As for the 12, it helps the consumer determine the base’s diameter. Since you’re dealing with an E12 bulb, it will have a 12mm base diameter.

When purchasing these bulbs, you’ll have to check the package carefully. Just remember that you might not find E12 anywhere on the outer packaging. Instead, E12 bulbs are marketed and sold as B10 bulbs. A B10 bulb is simply a build with an E12 base.

The B10 specification helps determine the bulb’s glass diameter which is 10*1/8 of an inch.

Difference Between E12 And B10

You’re likely searching for an intricate difference between these two bulbs. Typically, you’re not going to find one. Many people suspect that they’re drastically different, but they’re often the same.

The only difference is that the package may be labeled E12 or B10. Usually, E12 lightbulbs are sold in packages labeled B10. There is no difference between the two. Instead, E12 refers to the bulb’s base diameter while B10 describes its glass diameter.

If you buy a B10 bulb, you’re likely buying a B10 lightbulb with an E12 base.

Two Types Of B10 Bulbs

There is only one type of E12 base although there could be different bulb types. The majority of them have a B10 bulb shape or a blunt tip. However, there is a difference because B10 bulbs are available in at least two unique styles. You’ve already learned that there are B10 bulbs with an E12 base.

In addition to this, there is at least one alternative style. It is common for B10 bulbs to have a medium base or an E26 base. Although both have a B10 bulb diameter, they have drastically different appearances. Since the bulb has an E26 base, it is much wider at the bottom.

In other words, the portion that screws into the socket is noticeably thicker. Once you’ve narrowed your options to B10, you should have little trouble deciding whether you need an E12 or E26 bulb.

If your original bulb has a thin base, you’ll likely need to replace it with an E12 lightbulb.

Is E12 Same As Candelabra?

The E12 lightbulb base is often described as the Candelabra Edison screw. Again, you may not see E12 on any of the labels or packages.

Instead, you’ll have to look for a B10 bulb with an E12 base. E12 bulbs are regularly referred to as candelabra lightbulbs.

They’re used for decorative purposes and are usually only 40W or less. If you’re looking for a candelabra lightbulb, you’ll likely need an E12 bulb.

Use of E12 and B10 Fixtures

The E12 and B10 decorative design set them apart from other light bulb alternatives. The oval-like shape makes this the perfect light bulb for chandeliers, bathroom vanity lights, pendant lights, floor lamps, wall scones, ceiling fans, and desk lamps.  

Which Is Better For Indoor and Outdoor Use?

Both the E12 and B10 are available for indoor and outdoor use. The outdoor version is compatible with various porch lighting fixture brands.

Dimming Capability of B10 and E12

If you are a mood lighting type of person, you should be familiar with the B10 and E12’s dimming capability. Manufacturers utilize state-of-the-art technology to create dimmable B10 bulbs. The technology allows users to create the perfect environment for different settings.

The lowest dimmer setting is ideal for nurseries, hallways, children’s bedrooms, and bathrooms. It provides adequate lighting to lower the risk of a mishap when traveling from room to room.

The maximum setting is more suitable for home offices, reading rooms, onsite workspaces, and kitchens. The middle setting makes the ideal nightlight for seniors. Utilize this setting
