Energy saving light bulbs – the facts
There are three different types of energy-saving light bulb. These are: CFLS (compact flourescent lamps), halogens and LEDS (light emitting diodes).
DIFFERENT BULBS – DIFFERENT EFFICIENCY Traditional incandescent light bulbs are accepted as the least energy efficient bulb.
Of the newer more energy-efficient bulbs, the least efficient are the halogen type which use 20-30% less energy than a traditional bulb. Although CFLS are more expensive, they use 60-80% less energy than a traditional bulb and last much longer too. LEDS are the most efficient using up to 90% less energy than a traditional bulb.
RUNNING COSTS PER BULB A CFL bulb will cost you around £2.04 to run per year. And a LED bulb will cost around £1.71 per year.
Halogen bulbs are the most expensive to run, with an annual running cost of around £8.42 per bulb.
