What are the differences in lamp fittings?
There are many different lamp fittings available. These are the most common types:
Screw fittings
— The best-known are E14 (small Edison screw), E27 (standard Edison screw), and E40 (Goliath fitting).
Push-in fittings
— These lamps are inserted directly into the socket using one or more pins.
TL fittings
— Fluorescent tubes use specific fittings depending on the tube type and size.
Bayonet fittings
— These fittings are inserted and twisted so that side pins lock securely into place.
