So what is LED?

LED stands for Light Emitting Diode and is a semiconductor, similar to a computer chip, that when electrical current passes across visible light is produced, the visible light is blue in colour (LED's naturally want to be Blue).

LED's have been around for 50 years or so but until recently were only capable of producing very small amounts of light and only in Red, Blue and Green colours. The breakthrough in the last 10 years has been the ability to produce White tones of colour from the LED chip, once this was achieved the light output that manufacturers could produce from the chip has increased year on year.

It's only in the last 5 years or so that this light output has been sufficient enough to allow LED's to be used for general lighting purposes.

LED: The Revolution In Lighting

Here is one staggering fact: it is estimated that if every standard 60 Watt electric lamp in use in the USA were to be replaced with an LED light the annual energy savings would be an astronomical 35 terra-watt hours of electricity usage or $3.9 billion dollars and 20 million metric tons of carbon.

It is estimated that within the next 10 years LED products will account for more annual global sales than all other current forms of lighting combined. With this rate of global adaptation of LED lighting, Flourescent tubes, Halogen lamps and Sodium street lighting will be a thing of the past!
