Lamp Holders

Lamp holders, also known as light sockets, are fixtures used in lighting installations. They hold a bulb whilst also providing an electrical connection to it. It is essentially a connection between the wire and the bulb.
Some lamp holders also provide support for a pendant or lampshade.

Lampholders are designed for different lamp sizes. These include:

B15 / B22 (Bayonet) – Bayonet cap (BC) fittings use a two-prong holding mechanism, the code number determines the connection base diameter.
E14 / E27 / E40 (Edison Screw) – Edison screw fittings have a threaded connection, with the diameter determined by the base type code.
GU4 / GU5.3 / GU10 / GZ10 – Halogen and LED spotlight fittings are a low voltage type with a twist and lock connection.
G5 / G13 (Fluorescent tube) - Fluorescent and led strips feature a two-pin fitting at both ends.
R7s - Linear Halogen capsules for floodlights and up-lighters have a 7mm R7s cap at each end of a long quartz capsule.
G4 / GY6.35 / G9 - Miniature halogen capsule lamps commonly used in integrated fittings and appliances, such as cooker hoods and kitchen cabinet lights.
Lamp holders are also designed for specific light bulb types, for example, LED, GLS or CFL. It is essential that you choose a lamp holder that is compatible with your bulb, and vice versa.
