How do LED light bulbs work and how long do they last?

LED (Light Emitting Diode) technology set a new course based on efficiency and design. Its characteristics make it superior to other actual lighting systems.

LED light bulbs stand out from the rest. They consume up to 80% less electricity than incandescent light bulbs and they don’t give off heat and do not include contaminating components. This technology arrived with light bulbs that last approximately 50,000 hours.  This is equivalent to having them turned on for 5 years without interruption. For example, Halogen light bulbs, which represented a step forward, can reach up to 3,000 hours.

LED light bulbs are recyclable and unlike the regular fluorescent light bulbs, they do not contain mercury or other contaminants.

This LED technology is based on diodes. The diode is an electronic component with two points that allows the circulation of energy through it in one single direction. Because this component can vary its intensity, LEDs can generate a nearly infinite combination of colors.

LED light bulbs were invented in 1927, the Russian Oleg Lose started to experiment with this technology. However, his discovery went unnoticed for decades until being recognized in late 20th Century. The first LED emitted in the visible spectrum was developed in 1962. Their system changed the paradigm of lighting and was improved until the Japanese Isamu Akasaki and Hiroshi Amano and the American Shuji Nakamura developed the light bulb we know today.

With LEDs, any space can be totally reformed, offering original lighting effects form homes, commercial businesses and public roads because they are capable of illuminating almost any area, no matter how obscure it is: stairs, cabinets, display cases, plants and shelves.

Whether or not you have LED lighting, your electrical consumption represents around half of what you pay on the bill. Logically, the more efficient your light bulbs are, the less electricity you’ll consume. But how much will you pay for the electricity you consume? There are rates where you can choose sometimes when you don't pay anything.
