Small Screw (SES / E14)
This is one of the two most popular screw fittings, along with the larger E27. Edison Screw bulb caps were first developed by Thomas Edison in 1909. As you might imagine, the Small Screw fitting tends to be found on more compact, slimline lamps, and isn’t ordinarily used with the common GLS household bulb.
