Light Sockets

E27 B22 etc

  • What is the difference between a bayonet and screw globe?

    We manufacture globes that cater for both bayonet and screw connections.  The code allocated to each globe refers to the connection between the globe and the light socket.  The codes beginning with an 'E' refer to an edison screw fitting whereby the globe screws into the light socket.  The standard fitting is an E27(E26 for North America).  The E14 (or E12 North America) is a smaller fitting generally used for lamps and chandeliers.

    Codes beginning with a 'B' refer to bayonet fittings and are generally only found in Commonwealth countries. The B22 is the standard size, with B15 again generally used for lamps and chandeliers.

    The E40 and E39 (North America) was traditionally an industrial fitting.  Our goliath range of globes fall under this category.

    Please make sure when you are ordering globes and light fittings that they are compatible.

  • Lampholder/ Light Bulb Standards

    E27 is the most common type of Edison Screw base, It is often referred to as ES. The number ’27′ refers to the diameter of the globe's cap. This type of base is also compatible with Compact Fluorescent Globes and LED globes. E27 is a 240 Volt bulb, as is a standard Bayonet B22.

    We also stock E14 SES 240 Volt bulbs and now E40 GES 240 Volt bulbs

    Whilst we do stock 110 Volt E26 and E12 components for those countries that use that standard, not all bulb shapes are available.
