Reality Check: How does the LED Bulb fare against the competition?
Neutral Existence have published some useful insights into just how the LED bulb compares with the more traditional incandescent and compact florescent alternatives. 'LED’s work by using different semi-conducting materials to make electrons jump from one material to the other. This “electron jump” makes the electrons emit photons in the form of visible light, and the color of the light is dependant on the different materials used in the diode. This process uses much less electricity to create the light, however the intensity (lumens) are less than other forms of light.'
