LED, Light Emitting Diodes, as the name states, are diodes, a semiconductor that permits current flow in one direction. Light Emitting Diodes are known to last for long and for the same reason they are often misused. Light Emitting Diodes Lighting is actually a cluster of individual units. While some of the units produce while light, others generate light of varying wavelengths. Getting the combination right, delivers the desired light tone in any setting.
Light Emitting Diodes Lighting is gaining immense popularity because of their high levels of energy efficiency and many other advantaged they offer over traditional lighting. Incandescent bulbs use 98% of energy as heat whereas the Light Emitting Diodes lights bulbs are cool. Heat is not lost as energy in these lighting leading to high levels of energy savings.
Another major advantage is the long life of LED lights. While an incandescent light bulb is designed to last for a maximum of 1,000 hours, LED lights can last from 50,000 to 100,000 hours. Even fluorescent bulbs can last only up to a maximum of 10,000 hours. The durability of Light Emitting Diodes lights come from the fact that they do not contain any fragile filaments nor do they have any delicate tubes to deal with. In addition they are highly resistant to heat, cold and shock.
There are some reputable manufacturers of LED lights that guarantee a higher lumen per watt ratio. The LED light generates an average of 55 lumens per watt. While this is more or less comparable with fluorescent bulbs, incandescent bulbs are way behind with just around 15 lumens per watt. It is believed by the experts in the industry that the technology will soon be available that can take this ratio up to 130 lumens.
Another major advantage of LED lighting is that it is compatible with most systems. Models are available that that can easily replace incandescent and halogen bulbs. There are some popular models that are used under the cabinets for providing indirect lighting for restaurants, hotels, kitchens and other work spaces. LED bulbs are also available for special occasions such as Christmas and New Year decorations.
The cost of an LED bulb varies and depends on the brand, wattage and type. They are definitely costlier than others but offer true value for money because of the many distinct advantages they have over other types of lighting.
