The led lamps they are everywhere… in the red light of the digital alarm clock at night, in the green light of the mobile phone display, etc. Thanks to their fundamentally different nature than traditional light bulbs, they can be made safely and efficiently, so much so that they can be left on all night with very little energy consumption.
LED bulbs in fact, they ensure considerable energy savings as well as a lower environmental impact. This is confirmed by the manufacturing companies which assure that theand led bulbs they produce only 60 lumens (unlike the old traditional 40 watt incandescent bulbs which consumed 490 lumens) for a consumption of only 3.4 watts / hour.
The efficiency of the Led bulb it drops by 3% after the first 3,000 hours of lighting, then remains constant up to 100,000 hours which correspond to 11 years of uninterrupted use, and then has a 70% drop. The Led it heats little and this leads to a greater efficiency with less power dispersed and therefore less energy used.
And on an aesthetic level?
The Led bulbs they are certainly not the best in aesthetics but they allow different shades: warm or cold white light, and a wide range of colors such as red, blue, green, yellow.
The only problem is the cost still quite high but the transition toled illuminationin the house will bring a economic savingsor on the electricity bill not indifferent.
ALED bulbwhich consumes 10.8 W of power and emits 810 lumens of white light, it would replace the bulbs that consume 60 W in the house! With only 3.6W of power, the same brightness (250 lumens) emitted by one is guaranteed light bulb of 25 W.
In short, just think that every led bulb installed, it consumes about 1/6 of the energy required by your old light bulb, not to mention the lower impact on the environment. The led lamps represent the ecological lighting of the future.
