Energy saving lightbulbs have always been a bright idea - for your pocket and the environment. They use up to 80% less electricity than a conventional bulb but are just as bright.
Technology has moved on a lot since energy saving bulbs were first invented - their looks have improved, they are smaller, and they cost less.
Although a little more expensive than a normal bulb, it'll pay for itself within months, and it will keep saving money for the rest of its life. And since they last four times longer, you won't be paying out for new bulbs, which makes them even better value.
You'll save the most if you switch the bulbs in rooms you spend more time in. So if you only buy one energy saver replace a bulb in the room you live in most. But of course, the more energy savers you use, the more you'll save.
If you replace just one bulb, that will avoid 80kg of CO2 emissions. If every household in the UK replaced two incandescent bulbs with low energy bulbs, electricity consumption for lighting would drop by 40 per cent, a saving of 11,985 GWh per annum (more than Sizewell B nuclear power station produces each year).
