E14

LED light bulbs of various colors designed for easy installation into existing fittings and as "fit and forget" solution in a wide range of lighting applications. Can operate directly on the mains voltage 220-240 V AC. Socket E14 (Edison Screw, ES). The Edison screw fitting is a system of light bulb connectors, developed by Thomas Edison. The designation Exx refers to the diameter in millimeters, e.g. E14 has a diameter of 14 mm. In Europe and in countries which use 230-240 volts AC domestic power, the standard sizes for general purpose lamps are E14 and E27, although the Bayonet mount is also used. Other base sizes are used for small lamps, such as E10 and E11 for candelabra fixtures and on some Christmas lights. Larger sizes (E39, E40) are used for higher powered lighting, generally for lamps of over 250 watts. (Wikipedia)
