The incandescent bulbs disappear: it seeks the best substitute

may still you have not noticed, but we're about to say goodbye to the incandescent bulb life . Moreover, if you come to buy a 100 watt bulb at any store may no longer get because were allowed to manufacture and distribute more than one year . You can only buy if they still have stock.
And what will happen to the less powerful: the 60 watts will be discontinued in September 2011 and 40 and 25 watts the same month of 2012.

The incandescent bulb has had a long life. The invention is dated in the nineteenth century and certainly has lasted so long because of its simplicity: a metal filament that heats up and emits light in a glass ampoule under vacuum. However, this system is extremely reliable but has one major drawback: their low energy efficiency . Only 10% of the electricity for these devices is intended to illuminate, the other 90% or more, is dissipated as heat.

The measure being taken by the EU to phase out the bulbs 'lifetime' will save 80% of total energy consumed in lighting (and thus leave the Europeans to spend around 5,000 million euros per year) and prevent the emission of 15 tons of CO2 into the atmosphere. To give you an idea, that is the equivalent to the electricity consumption of a country like Romania in a year.

The energy crisis and the famous climate change require banishing wasteful incandescent lamp. But what is the best option to replace it?

In the market there are three options: the energy saving lamp, halogen bulb and LEDs. However, although all better by far the energy of traditional bulb, they also have many drawbacks.

The first is the price. If a 100 watt light bulb was worth about 60 cents, equivalent in brightness models are more expensive: the low energy out for 8-9 euros, the halogen lamp for 7-8 euros and one of 40 LEDs and 50 euros . However, the European Commission estimates that each household will save 20 to 50 euros per year in lighting to stop using the old bulbs and that including the higher cost that has to acquire new ones.

In the case of halogen bulbs Another drawback is its low efficiency . Very similar to traditional bulbs in this type of bulb is not empty but contains a gas that powers lighting and more resistant quartz crystal temperature. From 2012, the EU will only allow the halogen generation, which use 50% less energy and last three times longer than conventional bulbs.

low energy lamps now appear to be the best solution. consume 80% less and last 15 times longer than incandescent bulbs . Use a technology inherited from the classical fluorescence with a mercury vapor inside. And this is their main problem since this gas is toxic . As we do with batteries and batteries, these bulbs are due at the end of its life in a clean point to proceed to recycling.

The latest technology to arrive are the LED light emitting diodes. They use 90% less energy and have no toxic substances . Currently used as points of light on traffic lights, electronics or small position lights to create atmosphere, but its development in the domestic sphere is still in its infancy.
We doubt the latter will be the solution to lighting of households in the coming decades (at least until they invent something better.) That is why we will devote more space in the next post.

And the fluorescent ? Surely you are wondering why we have not included as a solution. The answer is simple: while consuming less than traditional power and offer more light, continue to generate toxic and light offer us cold and it is white, at least in Europe, not like for our households . Used in the kitchen, warehouse or office, but very few people decide to urge in their classrooms.
