An E27 light bulb is a man-made light source that is mechanically supported and electrically interfaced by an E27 medium screw base. E27 is the European variant of Edison screw base that is commonly found on general lighting service (GLS) lamps. The E27 base is 27 millimeters in diameter as measured across the peaks of the thread on the base (male) and is 26.67 millimeters in length. E27 screw bases are more widely used around the world than E26 screw bases which are adopted principally in countries in Americas (e.g. United States, Canada, Mexico, Colombia, Costa Rica, Venezuela, Cuba, Honduras, and Jamaica). E27 light bulbs have evolved from the standard incandescents to compact fluorescents and now LEDs. An E27-base LED bulb has the similar form factor, lumen output and light distribution of legacy light sources, allowing to replace, easily and operatively, each conventional lamp.
