LED Lights vs Incandescent Light Bulbs

LEDs consume not only less energy when they are used to enlighten us, but they are also more energy efficient during the manufacturing process than their predecessors to incandescent and CFLs. The result is a four times lower overall energy consumption if one uses LEDs if you use incandescent bulbs.

This is a very interesting conclusion provided by the U.S. Department of Energy’s Pacific Northwest National Laboratory published in a new report entitled “Life-Cycle Assessment of Energy and Environmental Impacts of LED Lighting Products.”

The report comes in 2 parts. The first compares the energy consumption of a LED compared to its counterparts incandescent (60W) and to fluorescent compact. The second party, as it measures the energy required by the cycle of manufacture of these different types of bulbs.

The report comes as from the first study to follow not only energy consumption during actual use of the bulb, but also the natural resources used for production, transport, use and disposal of the LEDs. The report examines the 15 criteria, such as climate change, waste and industrial pollution of air, soil and water.

According to the report, a classic LED uses 3900 megajoules (MJ) during the average lifetime of 20 million of lumen-hours, which is comparable to a CFL. However, an incandescent bulb uses almost four times more than energy – 15.100 MJ by 20 million hours lumen unit.

In order to produce these 20 million lumen-hours and given also the lifespan of the bulbs of each technology, must be used to compact choice 22 incandescent light bulbs or 3 fluorescent bulbs or LED bulb… The promise of LED technology for 2015 announce that when a 12.5 2011 LED is necessary to ensure these 20 million hour lumen, need more than 0.6 in 2015 and then from consumption of 12.5 W to 5.8W

Finally, the study indicates that one of the waste as much energy for the LEDs is the type of display used for packaging by the manufacturer… The packaging… it’s also another story…

The good news is that another study from the Navigant Consulting firm announced that LEDs are undeniably a disruptive technology making it obsolete to its precursors. The findings announced the disappearance of incandescent bulbs in 5 years is in 2017. Halogen bulbs or fluorescent Compact are entitled to one year of additional relief to disappear only in 6 years either in 2018.

Remains to LED bulbs to restore their image by not betraying consumers by electronics failures, by mortgaging not their duration (some manufacturers push LED performance to get a better light intensity at the expense of their lifetime) and offering fair prices.
