One of the greatest complements to sustainable energy is, without a doubt, LED lighting. Unlike previous generations of electric lamps, LED lights and bulbs use a minimal amount of energy and are capable of lasting a very long time. In fact, it is not beyond the realms of possibility for LED light bulbs to last as long as twenty years, if not longer, with a minimum of 5 or 10 years of warranted life.
LED – Light-Emitting Diode
In order to understand just how efficient and cost effective LED lighting is, it would be good to understand a little about how they work. LED stands for light-emitting diode and is the result of electricity passing through a semi-conductive material. The energy produced is used to light up multiple tiny diodes which combine together inside a single larger bulb that we refer to as an LED lamp.
Extremely Energy Efficient
Since very little electricity is used, LED lights do not produce a great deal of heat and are thus extremely energy efficient. Wastage through heat is where much of the energy is lost in conventional lamps - or incandescent lamps, to be exact. The small amount of heat that is produced in an LED light is transferred to a heat sink within the fitting which scatters the heat and helps the LED bulb to remain cool. Even after an LED light has been 'burning' for hours, it is still possible to reach up and unscrew the lamp from the fixture as it will only be slightly warm to the touch!
