With the emergence of new light sources such as compact fluorescent light bulbs and halogen incande

Since 1 September in the European Union (EU) of the twenty-seven can not buy these bulbs that have become part of the collective imagination as a symbol of having a brilliant idea, since it came into force banning manufacture Traditional incandescent bulbs and contaminants (invented by Edison 133 years ago), which involve not only benefits the environment but economical lumignon (80 saving per year per household).
Thanks to this first source of reliable light, humanity and independence of the sun could lengthen their workdays and nightfall, which meant a significant increase in productivity and further development.
The bulbs allowed to install more powerful systems of street lighting that increased lumignon pedestrian safety and vehicular traffic facilitated, led light hospitals, libraries, lumignon cafes and of course, houses.
With the emergence of new light sources such as compact fluorescent light bulbs and halogen incandescent were losing presence in public spaces, lumignon due to their low energy efficiency: on average, only 5% of its electricity consumption is transformed into light The rest becomes heat.
But it is in homes where incandescent found their place, becoming the preferred bulbs families appreciated the illuminating reds with its halls and rooms facing the coldness of the halogen and fluorescent.
Its much cheaper than its competitors, price was one of its strengths: an incandescent bulb costs about one euro, while a compact lumignon halogen is between 3 or 4 euros and 12, and modern LED lamps soar to 15 or 25 euros.
However, experts and Brussels agree on one point: the higher cost is largely offset by the savings in energy costs using the new bulbs versus primitive, as well as its durability.
The LED is emerging as the natural successor to incandescent, not only for its greater energy efficiency, but also because of its many applications (new screens lumignon of televisions, lumignon for example), immediate ignition and warm feeling lumignon it brings.
"It has all the advantages of early bulbs and none of its drawbacks," says Erice, who also predicts a significant drop in prices in the coming years, as technology advances and more widespread use.
