Generally, the two standards are harmonized, although several types of screw mount are still defined in only one standard. Instead, these bulbs should be used with E39 or E40 bases for safety. Disobeying this guideline can be a safety hazard since the base can melt due to the high temperatures. Though B11 bulbs have a distinct shape, there are other details of the bulb that you should consider: Base The most commonly used and interchangeable bases are E26 and E27. These bases have a similar thread size and can usually be used interchangeably. However, it’s important to note that the wattage and voltage of the bulb must also be compatible with the fixture. E39 and E40 The E26 and E27 are usually interchangeable, as are the E39 and E40, although less so; although there is only a 1mm difference in thread outside diameter, there is a small difference in pitch; an E40 cap will often fit in an E39 holder but not the other way around.

Uses of B11 Bulbs That tiny size difference (2mm) between E12 and E14 bulbs makes most buyers assume the two are the same. Alternatively, you can look at the printing on the bulb’s base. In most cases, the bulb will have an “E26” label with its wattage equivalent.

E12 and E14 bulbs are not the same.

Choose a color temperature that suits your needs and decorating style.
