The first thing to consider when buying bulbs for your home is the cap that you are going to need to make the bulb compatible with the fitting it is being used with.

This style of bulb comes in two different sizes, 22mm and 15mm, so is applicable to a large range of fittings that use the Bayonet function. This is one of the most popular styles of bulb and is used on most light fittings.
  • Edison Screw Cap: Named after the creative pioneer Thomas Edison, these bulbs are used all across the globe and come is a variety of different sizes. The ES/E27 fitting has a diameter of 27mm and is one of the most utilised bulb sizes in the world. Smaller sizes such as the SES fitting are great for use in decorative fittings and also things such as chandeliers which use multiple small light sources – these bulbs are mostly used in the UK and Europe.
  • Capsules: Capsules are measured by the size of the gap between the pins on the base. For example, a G9 bulb has a 9mm gap between each of the pins. G4 bulbs are most used in low voltage apparatus, whereas the G9 is capable of being used at a 240v mains outlet.

Spotlights: This style of bulb is rapidly becoming a major influence within the modern home. Spotlights are discreet, stylish, and produce brilliant lighting. These bulbs come in four main varieties; GU4, GU5.3, GU10, and GZ10. The GU10 and GZ10 are the same size, except the GU10 has a bevel around the base, whereas the GZ10 has a squared edge. This means the GZ10 bulbs cannot fit into GU10 fittings, however GU10 bulbs can fit into GZ10 fittings. This makes these bulbs very versatile and useful in your home.light bulbs
