LED bulbs offer more durability and economy when compared to fluorescent and incandescent
After the replacement of fluorescent light bulbs as an alternative for saving, LED lamps (abbreviation for light emitting diode) come to market with better energy performance than its predecessors, average durability of up to 20 years.
The LED Light Bulb Philips, the award winning American Bright Tomorrow Lighting ("Bright Tomorrow"), is an example of this generation of lamps. After 18 months of testing, the lamp has reached the U.S. market with efficiency up to 90% in light output (percentage of utilized energy is converted into light rather than heat), presenting a huge difference when compared to incandescent bulbs, which luminous efficiency is on average 8%, according to the National Institute for Energy Efficiency (INEE) of Brazil. That is, when you light an incandescent bulb, only 8% of the electricity it consumes is converted into light. The other 92% is lost as heat.
Fluorescent lamps, for example, has a luminous efficiency up to five times superior to incandescent lamps with the same power and are also more durable (about eight times higher than incandescent bulbs). Because of this are far more economical and is already being taken on an increasing scale in Brazil.
Comparing the energy efficiency of LED lamps in relation to fluorescent, the LED consumes less power to two times and as regards the durability also wins. While incandescent bulbs have a lifespan estimated at 1000 hours, fluorescents can last from 10 to 15,000 hours. Already LED Light Bulb and similar lamps last at least 25,000 hours. According Eletrobrás, taking into account the energy consumption and capacity of illumination, the LED lamps may be considered more advantageous to consumers because dispense constant changes.
Regardless of the brand or model chosen, there are significant advantages in power consumption when using CFLs and more, the LED lamps. Typical examples of more durable products, which has been stimulated by Akatu result in a much more efficient use of natural resources than incandescent bulbs. That is, because the lamps have a more durable use for approximately 25,000 hours, more than 25 times the filament, the use of natural resources, energy and water results in far less production per hour of use of the lamp, in the case of incandescent. These bulbs are more durable example of the items of "10 Ways to Responsible Production and Conscious Consumption", developed by Akatu to point out 10 ways that should characterize the sustainable production and consumption of the future.
On the other hand, compact fluorescent and LED lamps are more expensive than incandescent bulbs. In the case of compact fluorescent Akatu calculations indicate that the decrease in the consumption of energy leads to a reduction in the energy bill on 8 months, more pays the amount paid by the lamp.
So who makes the exchange of the fluorescent or incandescent lamps by LED, will be taking care of energy consumption and reducing the bill. At the same time, will be helping the planet, since the production, distribution and use of electricity they generate a series of negative impacts on society and the environment, either by the use of public resources that could be used in other services such as education and health , is the displacement of populations living in areas flooded by the dams necessary for the operation of a power plant, or the massive intervention in an area that is being transformed into a huge lake, or by carbon emissions from the process plant construction and transmission lines. Making the switch to more efficient light bulbs means eating with awareness, contributing also to prevent climate change and global warming.
On the issue of toxicity when compared to fluorescent lamps containing mercury in its composition, the LED lamps have a lower pollution potential and easier to recycle. However, the proper disposal of any lamp is essential and requires special care by the consumer. Arsenic, lead and other chemicals are part of its composition and can be harmful to health.
With subsidies from the U.S. government, the unity of the LED Light Bulb is being marketed in the United States for U$ 23 (R$ 41). According to Philips, in Brazil there are already models similar to the LED lamps LED Light Bulb, as MasterLED 12W and 17W Bulb technology that can replace an incandescent lamp of 60W and 75W, respectively.
