Many people have been changing the traditional by incorporating the latest technology in lighting market. Not only saves as it is more environmentally friendly. Learn why.
It is inevitable! The end of the month and there’s always a concern with the value of the electricity bill. As much as we take advantage of the sunlight during the day, at night we have to resort to artificial lighting. According to the energy Portal, lighting costs represent, on average, about 15% of the electricity bill. In most cases, the amount can be greatly reduced if we trade traditional bulbs for LED, acronym of light-emitting diode, light emitting diode in Portuguese, despite the initial investment.
What are the advantages of this Exchange?
- LED bulbs have an average life of 50,000 hours. If you have the light on all the days between the and the 12:00 am 6:00 pm, lamps can last for 23 years. Despite picking a larger initial expenditure, the medium and long term the investment turns out to compensate.
- Will reduce CO2 emissions. Thanks to the minimum rated input power, LED lighting reduces emissions of carbon dioxide, thus being a friend of the environment.
- The rays of light from the LED light bulbs are exempt from UV (ultraviolet) and IR (infrared rays), which makes walls, tables and plants, for example, do not become damaged over time because of the heat.
- Due to clear and intense colors that the models for sale on the market present and ranging from the cold white, warm white, red, green, blue and yellow, if you know how to make a good combination of LED light bulbs, you can create several types of environments in your home.
- The LED light bulbs are more expensive than the traditional but last longer. How, in practical terms, can save up to 70% of permit energy, spend less money. In some cases, in twelve months you can feel any return on investment.
The health risks
Despite being more luminous, consume less and ensure greater energy efficiency, some alert to possible health risks in case of intensive use, which is to avoid. In a statement, the American Medical Association (AMA) came alert in mid-2016, to the potential dangers of excessive exposure. A study at the University of California, in the United States, says that the red color may contain lead and arsenic, among other potentially dangerous substances.
In December of the same year, another group of international research, which integrates a docent of the port, also drew attention to the harm of illumination, associating it with the increased likelihood of developing diabetes, obesity and cancer of the breast and prostate. ”Artificial lighting, with very white LED relief, is potentially harmful to human health due to the blue component very pronounced in your spectrum”, mentioned publicly Raul Lima, researcher at the school of health.
