LEDs have been used widely for decades in other applications-forming the numbers on digital clocks, lighting up watches and cell phones and, when used in clusters, illuminating traffic lights and forming the images on large outdoor television screens.
Until recently, LED lighting has been impractical for most other everyday applications because it is built around costly semiconductor technology. But the price of semiconductor materials has dropped in recent years, opening the door for some exciting changes in energy-efficient, green-friendly lighting options.
What are the main advantages to using LED light?
* Very long life. The LEDs can run continuously for over 100,000 hours without failure, while fluorescent values wander around 28,000 hours, and 3.000 to 8.000 hours fluorescent light bulbs and incandescent bulbs from 1.000 to 2.000 hours.
* From 1910 to 1950 times more efficient in a matter of energy, reduces operating costs by up to 90%.
* Eco-friendly, mercury-free to be saving energy helps reduce emissions of carbon dioxide (CO2) released into the atmosphere.
* Little or no heat generation, safe to touch.
* Resistant to shock, vibration, frequent switching on and off and extreme temperatures.
