Light bulbs guide
Choosing bulbs for your lights can be tricky. There's a range of types and fittings, all with different codes to identify how they should be used. Some serve a functional purpose for lamps or spotlights, while others can be used to make a real style statement.
Luckily our guide is here to help you find the right bulbs for the lighting in your home.
Light bulb types
All light bulbs have a code to identify their type of fitting. The letters tend to stand for the name of the fitting and the numbers are the diameter of the fitting in millimeters. For example, an E27 is an Edison Screw bulb with a diameter of 27 millimeters.

Benefits of LED light bulbs
LED light bulbs will soon be the only type of bulb that you can buy in the UK. LED bulbs can last up to 25 years, far longer than halogen bulbs, which may need replacing after 1 year of use. LEDs are far more cost effective, saving you up to £240 a year, while halogens produce more heat and use 85% more power.
