Energy saving thanks to LED bulbs

LED bulbs consume little and last a long time, allow good energy savings if you buy the right ones and are also beautiful to look at.

They consume little and last a lot, they allow a good energy saving if you buy the right ones and they are also beautiful to look at. The LED bulbs, also thanks to the banning of the classic incandescent light bulb, have revolutionized the world of lighting in the true sense of the word.

At home and in offices, but also in places of public relevance, they are now i LED, Light Emitting Diode, ie the light emitting diodes, to be the master.

Why is it worth switching to LED bulbs? Because it is a much more efficient technology and, with the same current consumed, a LED bulb produces much more light than an old halogen bulb.

It goes without saying, therefore, that there is a substantial saving in the bill, also comforted by the fact that LEDs have a life cycle of around 20-50 thousand hours.

What are LED bulbs

Since their appearance on the American market in the 70s, the ability of these bulbs to bring numerous advantages in daily life was immediately clear. From an environmental point of view, in fact, thanks to a good relationship between efficacy and duration, but also from a chromatic point of view (there are many ranges of colors) and from a lighting point of view (they allow immediate ignition and a certain directionability of light), LED bulbs have immediately laid down the law.

The LED is made up of a series of levels assembled semiconductor materials and wrapped in a transparent finish gasket that allows the light to escape. Above all, the latest generation bulbs are also made of glass and contain a filament inside which makes them very similar to old incandescent bulbs.

LED bulbs allow energy savings of about 90% compared to old classic bulbs and last for about 10-15 years of average use. This is why there is a great cost reduction and a significant savings in the bill. They have instant ignition and withstand many on and off cycles.
Finally, LED bulbs can have warm, cold, natural light, do not heat up and can be used in all types of lighting fixtures.

How much can you save with LED bulbs?

An LED bulb consumes half of a fluorescent bulb and about one fifth of an incandescent one. Despite having a substantial initial cost - but now there is really a wide choice on the market - in the long term there is good savings. The LED lights, in addition to UV rays, do not even emit infrared and therefore do not give off heat and, by not raising the temperature of the room, they also reduce the need to turn on the air conditioning.

The ABC of LED bulbs

In order to buy the right LED bulbs, it is good to know a few things:

1. These bulbs are not chosen on the basis of the power expressed in Watts but on the basis of the light intensity, expressed in lumen. The lumen (lm) is therefore the indication of the light intensity. Around 2000 lm it is about 150 Watts, between 500 and 1000 lumens it is around 60 Watts, while a light bulb below 500 lumens is indicated as a light point for a desk.
2. In general, the LEDs are at full capacity as soon as they turn on, but from the packaging you can tell how long it takes for the bulb to turn on.
3. Hot or cold? The color of the light is given by the indication of the Kelvin degrees. Warm light has a yellow color and its degree of heat ranges from 2.700 to 3 degrees Kelvin. The cold light has a white color, tending to blue, and its degree of heat ranges from 5 thousand to 6.500 degrees K. The natural light, recommended in the bathroom and in the kitchen, is neutral white and its degree of heat is of about 4 thousand degrees K.
4. Finally, on the packaging there is also an indication - the so-called dimmer - to understand if the bulb can be connected to a device that regulates its intensity.
