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.
