Screw (ES / E27)
The Edison Screw fitting was developed by Thomas Edison in 1909, and is now available in a variety of sizes. The more common are the medium-sized E27 and the smaller E14. The generic term ‘screw fit’ usually refers to E27. Bulbs are simply threaded into the lamp holder in clockwise rotation for installation.
