Fitting LED bulbs throughout your home is a great way to save money and help the environment.

Lighting can make up a considerable proportion of your electricity use at home, especially during winter months and in rooms where you keep lights on for several hours, like your kitchen and living room.

You should replace the old incandescent bulbs, halogen bulbs, and the curly low-energy lights known as compact fluorescent (CFL) bulbs.

LED bulbs use a lot less energy, last a lot longer than other types of bulbs, and many are dimmable, too. They emit no UV or IR and are mercury free.

Common types of LED bulb

Classic-shaped bulbs

LED bulbs are the best choice for the traditional round bulbs – either in a bayonet fitting or screw fitting.


LED bulbs are great for spotlights. There’s lots of choice, including bright bulbs that match or exceed the light levels of halogen bulbs. We recommend the GU10 spotlights. They’re the ones that go in with a push and twist and are 240V.

There’s not quite as much saving for MR16, but still worth doing. They have 2 pins that just push in, no twist, and they have a ‘driver’ that reduces the voltage to 12V. With MR16 the LED bulbs do not offer the same output-for-wattage rating. The driver might also have to be replaced by an electrician.

Candle bulbs

Lots of choice here, too. Newer, brighter bulbs have become available at affordable prices. We have seen light levels match that of halogen. When recently trialling three of the Philips 6W Master LED Candle in a three-bulb candelabra, we found the light levels very bright.

Other fittings

Many other types of LED fittings can be found, too. You should find an LED equivalent for most bulbs around the house.
