LED Lights.

Light Emitting Diodes (LED)

LEDs, the King of Bulbs.

Having the longest lifespan with most-energy saving operation, without containing Mercury should make LED (Light Emitting Diodes) bulbs to be the champion of green competition. Yet the bulb still has a shortage.  Here is a review of the yet-to-be-champion :

Some advantages that make LED bulbs surpass the other light bulbs:

Longer lifespan : LED’s lifespan is 60,000 hours, 10 times longer than the CFL’s, 6,000 hours, or  80 times longer than the incandescent bulb’s  750-1,000 hours.

Energy efficient. LEDs bulbs are very energy efficient, it consume less 80-90% than the Incandescent light bulbs do.

Efficient use:  LED produced direct light, only focused area is eliminated. Therefore it does not consume lot of energy to produce the light. The bulbs are available in very low wattage, starting even from 1 watt.

Temperature tolerant:  Unlike CFL, LEDs can be used in low temperature; therefore it is ideal for outdoor lighting.

Dimmable and available in several shades and colors.

Price:  LED’s purchase price is still much higher than the other bulbs’. A LED bulb of equivalent 60 watt light costs about  $ 75, however it lasts 10 times longer than a CFL bulb.  So the price of LED bulb is still favorable.

Easy dispose: As the LED bulb does not contain mercury as CFL, disposing the dead bulb is easy.

LEDs also have benefits for the environment:

Less Emission. LED bulb is an environmentally friendly option, as it generates less emission. According to the Energy Information Administration of U.S. Department of Energy, A single kilowatt-hour of electricity will generate 1.34 pounds (610 g) of CO2 emissions. By assuming the average light bulb is switched on for 10 hours a day, a single 40-watt incandescent bulb will generate 196 pounds (89 kg) of CO2 every year while LED bulb generates only 63 pounds (29 kg) over the same duration. Exchanging all incandescent bulbs for new LEDs, a building’s carbon footprint from lighting can be reduced by 68%. No harmful chemical : Lets remember again, LEDs bulbs  are mercury free, therefore they are more eco friendly. Depress the industry rate : In regard to lifespan comparison, using 1  LED bulb can prevent you from  replacing incandescent bulb 50 times  or  CFL 10 times. This leads to a less production and distribution of light bulbs which can reduce the emission and pollutant generated by the involved processes :  natural resource expenditures, packaging plus transportation. Thus by using LED bulb we can  protect the environment by  many ways.

The only LEDs’ shortcoming :

But LEDs still have some drawbacks for home lighting. They only deliver direct  light. The narrow focus  light does not illuminate wide area as CFLs do, therefore it is not quite ideal for home lighting.

LEDs’ Ideal use for  residential lighting :

LEDs are still on their way to surpass the other bulbs in lighting up your home, but it does not mean that they have no place at all in your home. Years ago,  LED lamps popped in  our home just once a year, to lighten up our Christmas tree. Today, LEDs have been doing far more : as night light, desk lamp, stairway or ceiling lighting. As LEDs can be used in cold wheather, they are also ideal for outdoor lamps,  An LED bulb can light your veranda, terrace, balcony, porch or driveway, staircase or hallway all night, all in less energy and longer lifespan than your old bulbs’.

LEDs could reduce national energy consumption for lighting by 29% by 2025. That would save U.S. households $125 billion on their electric bills. The Department of Energy .

Conclusion :

Simply put, LEDs  still are in early stages for  a wider application of home lighting.  Yet, they are excellent for outdoor lamps, and  if you are an energy-saver who care for  applying efficient light just on the required spot, then LEDs are the most suitable bulbs for you. They are energy saving and they are most environment friendly. Give LED bulbs  more chance in your home, and you will give more  chance to our planet.
