How energy efficient is the LED compared to halogen?

LEDs require very little electricity to power them up. This is because they are extremely efficient. Their design converts approximately 90% of the electricity they consume into light. In a conventional light the figure is more like 10%, with the rest of the electricity effectively wasted in lost heat. Our down lighters, for example, draw only 2 to 6 Watts of electricity to light up, compared to the 35- 50 Watts drawn by a traditional halogen down lighter. That is a saving in electricity consumption of approximately 85%-94%. Not bad when the cost of electricity is continually rising. They will last between 26000-50,000 hours which can be 50 xs longer than a halogen light. This means no maintenance for 8-20 years.
