A typical New Zealand household could
save between $100 and $150 a year on its power bill by switching to LED lightbulbs - but half of us still haven't bothered. A new survey commissioned by the Energy Efficiency and Conservation Authority (EECA) showed only half the 500 people it questioned had installed any LED bulbs in their homes. But the rate of take-up is increasing. Three years ago, just 18 per cent had made the switch. An LED lightbulb produces "light-emitting diodes". The bulbs use up to 85 per cent less power to provide the same amount of light as an incandescent bulb. Each LED bulb is meant to last at least 15,000 hours.
