LEDs: Energy Efficiency Factor

As we move into a more and more eco-conscious world, concern with the use of energy efficient lighting has become more important. It is believed that by 2010, which is just a few short weeks away from beginning, LEDs will be the most energy efficient lighting available.

Energy efficiency for lighting is measured by luminous efficacy, which is measured in lumens per watt. This is a measurement of how much light is produced from each watt of electricity used by the light. Today, LED lights produce 45 to 50 lumens per watt, but as further development occurs, it is expected that LEDs will reach 160 lumens per watt by 2025.

Something else to keep in mind about LEDs is while they use a low amount of energy, they also produce a low light output. True energy efficiency provides both a low energy user that produces a quality amount of light output. This is why work is still underway to continue to improve the energy efficiency of LEDs.
