LED Lighting

LEDs have come a long way from their beginnings as dim indicator lights. In recent years high powered LEDs have become a cost effective means of general interior lighting.

Compared to incandescent light bulbs, LED light bulbs use up to 80% less energy, last more than 20 years and unlike CFL bulbs, they don’t contain any toxic mercury. They are now available online and in most stores from between £4 and £10 each:

As they are still relatively expensive, the most cost-effective option is to replace always-on or frequently used lighting.

GU10 halogen down lighters should be changed to LED as they are hideously inefficient, running upwards of 40W per bulb. A fixture with just 4 will consume between 160 and 200 watts. A sea of them in a ceiling can use several thousand watts. Replacing these with LED using between 5 and 10 watts per bulb drastically reduces power consumption.

Do note that with LED bulbs low cost can be a false economy as they have a higher tendency for premature failure. The more expensive (£10 for GU10) are generally better quality and longer life.

Incandescent lighting burns up to 25% of the average home electricity budget and therefore a 90% reduction could quickly save you over 20% of your electricity bill. LED bulbs have become a lot more affordable in the last year or so and most types of existing light bulb can be replaced.
