Add convenience and versatility to your smart lighting system

When shopping or dealing with any type of light bulb, you have probably come across “E26.” The misinterpreted term describes a bulbs base and has sets the standard for most smart bulbs you will encounter.


What is an E26 smart bulb?

E26 refers to the light bulbs cap or base - the metallic underside of the bulb that allows for electrical contact and mechanical alteration. The letter “E” refers to the Edison Screw, the most standard lamp base named after the electrical device pioneer Thomas Edison. The number 26 specifies the diameter in millimeters, around 1 inch. There are no structural differences between traditional E26 bulbs and ‘smart’ E26 bulbs as the newer bulbs have adopted the traditional base. However, E26 smart bulbs come with enhanced features that enable more control options. This includes:

  • Remote control
  • In app dimming and color alteration
  • Schedule setting
  • Voice control (with compatible voice assistant)

Where to use E26 smart bulbs

The E26 bulb makes use of the E26 base for mounting and electrical contact. E26 bulbs are a standard in North America, Japan and other countries that use 120V AC. The E26 base makes installing and reinstalling bulbs easy. Simply screw right to tighten the bulb into place, and unscrew left to loosen and remove the bulb. The widespread use of this cap also simplifies the shopping process, as you won’t have to worry about a bulb not fitting.

How do you see if the smart bulb is an E26?

The E26 base is characterized by the metallic base with screw threads. If you recognize this and can approximate that it’s about 1 inch in diameter, you are most likely looking at an E26. In addition, most smart bulb manufacturers will print E26 alongside the wattage and brightness as well as on the original packaging.

Common Misconceptions

E26 bulbs are often confused with indicating a bulb's shape. E26 only refers to base or cap that goes in contact with the lamp holder! However, many different bulb shapes still use the E26 base. Most A19, BR30 and PAR smart LED bulbs use an E26 base. E26 is also not the same as its European counterpart E27. Although they have the same shape, the voltage is different as European countries operate at 240 V AC.
