LED lighting is the topic of discussion around the world when it comes to debates about climate change and energy conservation. Everyone has come to recognize the superiority of the LED technology over all other technologies used in lighting. People promote the low consumption of the LED bulbs, the safety advantages in terms of weak heat dissipation and the guarantee of a return on investment in both the medium and long terms. For these reasons, many governments are putting LED lighting in the list of technologies to be urgently promoted in order to respect the environment. The electroluminescent diode bulb, or LED, is a type of electric bulb that uses electroluminescent diodes of a semi-conductor to generate light. The performance is even more interesting even without calling upon fluorescent phenomena. The life span of LED lamps is even longer than these other relatively recent inventions with their own incontrovertible advantage, being that LED bulbs don't suffer in any way from repetitive switching off and on. The life expectancy of an LED bulb is 15 to 25 times longer than an incandescent bulb, and 3 to 4 times longer than a CFL.
