The LED bulbs they are spreading more and more rapidly because they are more efficient than incandescent lamps, save electricity, are durable and resistant. Here's in detail everything you need to know about LED lamps…
Let's start with the acronym LED that stands for Light Emitting Diode (light emitting diode), a technology patented in 1962 by Nick Holonyak, an American inventor and, at the time, a consultant to General Electric.
Since then the technology has evolved and above all it has become cheaper even if still today the cost of an LED bulb it is still slightly higher than that of one of the old incandescent bulbs.
THE advantages to use a led bulb but I am notable, here they are:
1) the led bulbs they have one duration between 50,000 and 80,000 hours of use equal to over 6 years of continuous theoretical use! Far longer than the approximately 1,000 hour lifespan of old incandescent bulbs.
2) the led bulbs consume less because they are more efficient and disperse less energy than incandescent bulbs which transformed light only 10% of the energy consumed.
3) the led bulbs "wear out slowly" giving us the opportunity to change them when we realize "that they make less light" and eliminating the risk of a light bulb "suddenly burned out" without warning with the relative inconveniences.
4) the led bulbs are "ecological" as they absorb less energy from the electricity grid, allowing savings for individuals and the community.
5) the led bulbs are versatile: they can generate a wide spectrum of lights, warmer or colder, they can emit a light of different colors and of different types: continuous or intermittent (as needed for example by lights for Christmas trees).
Also for these reasons the European Union,with directive (EU) No 1194/2012 has decided to ban the production of all incandescent bulbs for domestic lighting by requiring the replacement with low-consumption ones and with LED ones, obviously all having "backwards compatible connections" with the old incandescent bulbs.
The technology with which the LED bulbs It is also improving more and more so that it will be more and more convenient and its uses increasingly widespread: even in the field of street lighting, for example, its use is growing rapidly.
LED bulbs: buying guide
There led technology lends itself to a large-scale and low-cost production, also within the reach of many small Far Eastern companies seeking to distribute their products directly on the Internet at lower prices.
The our advice however, it is to pay attention to your purchases, in any case orienting yourself towards known and reliable brands, however, can also be purchased on the Internet thus obtaining savings compared to traditional shops.
Whereas a led bulb will last several years and that the average cost of the best bulbs does not reach 15 euros, our advice is aim for quality.
Between best-selling, reliable products with positive reviews of users we point out the Philips LED bulb, with frosted drop shape, power of 9.5 W corresponding to 60 W of old incandescent bulbs, E27 socket (the one used in Italy for most chandeliers) and warm white light
A great product offering a even more intense light (12 W equal to 75 W incandescent) is the LED Lighting EVER bulb from Samsung, always with warm white light.
The writings you find on the packs of LED bulbs as "9.5 W -> 60 W" therefore means that the Watts of that bulb are 9.5 W which correspond to "the intensity of light" you had with an old incandescent bulb of 60 W, due to the greater efficiency and the lower light dispersion of LED technology that we talked about at the beginning of this article.
The words in English "warm white"Mean"hot light“.
The written "84% energy saving”Instead indicates that with this bulb you will get a average energy savings of 84% than consumed with an old 60W incandescent bulb.
