Led Lighting - Exploring Every Aspect Of Energy Saving

LEDs or light emitting diodes are lighting devices which until very recently were used only in single bulbs and small electronic devices. But now LED lighting is being used extensively to meet all lighting requirements. With their highly efficient lighting qualities, they have come to revolutionize the home as well as commercial lighting systems.

LED lighting is a major breakthrough in the lighting industry and has continued to evolve throughout the years. One of the most important benefits of LED lighting is that it saves energy along with being eco friendly. This is a tough combination to beat. Besides lighting up homes and offices at reduced costs, they also reduce carbon emissions. Though the initial cost of LED lights is slightly on the higher side, the energy savings that it brings throughout the years more than compensates for the investment. LED lighting fixtures are available for almost all lighting needs.

If you think of holiday lighting, the traditional incandescent bulb uses 6 watts per bulb. Compare that to a mere .08 watts used by an LED bulb. A strand of 50 traditional incandescent lights running on an average of five hours a day for the entire 30 days of the season would cost about $5 per day. But to run the same number of LED lights, it costs just $6 for the entire season. Look at how the energy savings add up if you use LED lighting fixtures for your other lighting needs as well.

LEDs last much longer than the fluorescent and incandescent light bulbs because they have no filaments in them. LEDs also generate lesser heat compared to their traditional counterparts; consequently they have a very long life. The life span of an LED lighting fixture is estimated to be 100,000 hours. Since the heat output is limited, they also make for safer decorating. Not only that, it directly impacts the air conditioning bill. When the light bulbs do not warm up the entire house, you do not need to keep the air conditioner on longer. This is advantageous especially in offices where the computers that are used inside generate a lot of heat and the air conditioning costs are quite high. If the heat produced by the lighting fixtures can be eliminated, it translates to great cost savings every year. The output of light which the LEDs emit over the years is consistent; studies have shown that the amount of light given out by a 12-Watt LED is comparable to that of a 65-Watt incandescent bulb. It does not fade away or emit lesser light as time goes by. Besides the above features the LEDs are also major energy saving devices since they have a brighter colored light, they emit light the moment the switch is turned on, they don't flicker when the light is dimmed and do not consume energy when they are turned off.

These benefits are useful to homeowners as well as those in the manufacturing sector. LEDs in the earlier times were used only for their different colors, but technological advancements have introduced white LEDs. They can be used to light up areas that require bight light such as hotels, casinos as well as houses. They consume just a fraction of energy as compared to traditional bulbs to generate the same amount of light.

how many watts do an ordinay lcd say 17" laptop screen use compared to an LED one?

is it much?

I could not give you a figure however, leds use less current as they are a cold light. LCD displays are illuminated by a high efficiency fluorescent tube. The energy loss in leds is very low as it is a cold light, the LCD is a warm light so more energy is lost as heat. http://www.trilogicuk.co.uk
