In part one of our discussion around energy efficient lighting and the impact it is making in reducing electricity usage at residential and business level, we introduced the benefits of l.e.d. lighting installation and why these ‘miracle lights’ are the absolute future of all lighting applications. In part 2, we take a closer look at the technology and why we should embrace it.
L.E.D. Lighting – 21st Century Lighting Technology
It is estimated that if all light sources in the world were suddenly switched to l.e.d. light technology, the global energy usage would drop by 4 percent. Doesn’t sound a lot? We this is equivalent to an astounding 3.5 Giga Watts of energy annually which is HUGE.
We discussed the figures with our local inner west electrician, Windon Electrical Services, who are run by Liam Windon. The benefits of l.e.d. lighting are so profound that it begs the question why would anyone NOT use this amazing technology. The benefits include:
Astounding Energy Equivalence
A 12 watt l.e.d. light globe can generate the same luminosity as a 70 watt standard incandescent light globe, in some instances this could be up to a 90 percent energy reduction for the same light intensity output.
Manufacturing Credibility and Environmental Sustainability
L.e.d. lamps are manufactured using l.e.d.’s that are essentially made from a number of l.e.d.’s mounted in a frame and encased in a glass ‘capsule’ with or without voltage dropping circuitry. L.e.d.’s are made from semiconducting material – generally silicon which is one of the most abundant and stable materials found on earth. The contain no cadmium, unstable gasses, lead or any other hazardous material that is potentially damaging to the environment. They are 100 percent recyclable.
Low Energy Input Manufacturing Process
As with solar panels, the environmental ‘footprint’ at the manufacturing end is equally as important in assessing the environmental benefits of any technology. If the energy inputs are high, at the manufacturing level, then any energy saving benefits of the devices, in this instance, l.e.d. lights, may be mitigated. It is estimated that environmental ‘payback’ energy input credits period is less than 3 months for an l.e.d. light globe. This compares to an average life expectancy of 12 years for a l.e.d. light globe.

In the next part of this series we look at more benefits of this amazing technology. Thanks again to Windon Electrical Services for their input.
