As one of the most rapidly-developing lighting technologies today, LED (light emitting diode) lights are extremely energy efficient: when compared to other types of lights, quality LED light bulbs last longer, are far more durable, and offer comparable – if not better – light quality. All this will effectively result in lower energy bills and greater energy savings. Using at least 75% less energy and lasting 25 times longer than typical incandescent lighting, LED lighting technology has the potential to fundamentally change the future of lighting in Australia – especially in terms of residential lighting.
Widespread use of LED lighting in your home or office offers you the greatest potential to save big when it comes to your energy bills, thanks to their one of a kind design and unique construction. But just how different are LED lights to traditional lighting sources such as incandescent bulbs and CFLs (compact fluorescentlamps) – and how do they stack up in terms of performance when compared to other lights?
The most notable and key differences found in LED lights include the following:
- Light emitting diodes are roughly the size of a fleck of pepper – a mixture of red, green, and blue LEDs is typically used in order to make white light.
- LEDs effectively emit light in a specific direction, therefore reducing the need for reflectors and diffusers in order to trap light. This feature alone makes them significantly more energy efficient for many functions and uses, such as in task lighting and recessed downlights. With other lighting sources, their light must be reflected towards the desired direction, with more than half the light itself never actually leaving the fixture.
- LEDs also emit very little heat: in comparison, CFLs release roughly 80% of their energy as heat while incandescent bulbs release 90% of their energy as heat.
