Also known as Edison caps, E14 and E27 bulb fittings resemble a screw shape with the number referring to the diameter of the fitting. This means E14 fittings are thinner than E27, but still have the distinctive screw shape.
Bayonet bulbs use a twist and lock motion to install. Unlike the Edison caps, they instead feature two prongs on either side. Widely used in most UK homes, you simply need to push and twist the bulb to connect it.
GU10 bulbs are commonly used for spotlights or downlights in kitchens or bathrooms. They connect via two pins on the base of the bulb. Suitable for both domestic and commercial use, they feature tiny glass surfaces on the inside that help to bounce light around the room.
The simplest way to check what size fitting you need is to look at the bulb you’re replacing. Most of them will include the fitting type somewhere on the underside of the bulb.
