What is a E27 bulb?

An E27 bulb is a light bulb with an Edison screw base that measures 27mm. This type of bulb is the most commonly found Edison screw variant and is often known as an 'ES' light bulb. It is a general rule that if the base diameter is not specified on an Edison Screw light bulb, it is accepted that it is an E27. Small Edison screw bulbs are available that measure 14mm for the smaller fittings. We also have giant Edison screw base bulbs that have a diameter of 40mm.
