Reference: Edison Screw from Wikipedia
Belonging to Edison screw base, e12 bulb base and e26 bulb base are two commonly-used thread size that groups for main supply lamps. So, when it turns to the difference between an e12 light bulb or e26 light bulb, let's make clear what do screw base exactly mean and how do they work ahead of all.

What are screw bases?
Edison screw base is a standard light bulb socket for electric light bulbs, which has now displaced other socket types for general lighting in North America and continental Europe. Similar to the light bulb shapes' naming rule, the "E" indicates that the bulb has an Edison base and the numerical part is the diameter of the base in millimeters. Therefore, an e12 bulb refers to the bulb with a base diameter of 12 millimeters while an e26 bulb is 26 mm in diameter.
How do screw-based bulbs work?
In an incandescent or halogen screw base light bulb, two contact wires connect the filament to the base of the light bulb, where the electrical voltage connects to the light bulb. The contact wires are soldered to the base metal at two different points on the base in order to keep them affixed to the base metal.
If the contact wires were not permanently affixed to the base metal, electrical current would not be able to continuously flow through the wires to energize the filament into producing light. One of the contact wires is soldered on the side of the base, and the other is soldered at the bottom. Therefore, the light bulb makes electrical contact at two points on the base.

Mechanical Differences between E26 Base and E12 Base
Governed by the IEC standards, manufacturing of Edison screw bulb bases have the required dimensions for E26 and E12, respectively. And despite what is commonly described as 14 mm difference between E26 and E12 screw dimensions, their length of screw and insulator height requirements are totally different.

Usage Variance between E26 LED Bulb and E12 LED Bulb
Apart from their different diameters, e12 bulb and e26 bulb are also designed to diverse usages for them to work better in different spaces of your home.
E26 LED Bulb
E26 led bulbs are primarily used in North America, which commonly screwed in standard light fixtures to act as general lighting, such as ceiling lights, lamps, can lights, porch lights and flood light fixtures, and vanity lights. Bulbs with these base types are available in many different styles.
Common bulb shapes with E26 bases:
A-shaped bulbs: A19, A15, A21
Globe-shaped bulbs: G30, G25, G16.5
PAR spotlight and flood light bulbs: PAR16, PAR20, PAR30, PAR38
BR (bulged reflector) spotlight and floodlight bulbs: BR20, BR30, BR40
E12 LED Bulb - Candelabra Bulbs
Popular in North America either, bulbs with e12 bases are commonly used for decorative applications, such as chandeliers, wall lamp, Christmas lights, restaurant pendant lights, ornamental lights, residential or commercial string lights, and night lights. Many bulbs with these bases are designed to mimic the look of a candle flame.
Common bulb shapes with E12 bases:
Small tube-shaped bulbs: T8, T6, T22
Candle-flame-shaped bulbs: C7, C9, CA10, B10
Small globe-shaped bulbs: G14, G16, G50
