Some of who are currently reading this article might have learnt about LED in our school time or would have learnt about it by some curiosity. LEDs are light emitting diodes, well most like to call them by the name just led as it is far better to call it this way. LEDs are very energy efficient and take very less electrical power to work. That means they require very less voltage and operate properly at minimal wattage.
At present, we know of three light four commonly used artificial light sources like incandescent bulbs that so many of us use at our homes, the CFLs or compact fluorescent light bulbs, the halogen incandescent bulbs and least used one is the led. While incandescent bulbs operate at high voltage and also take in a lot of electrical power, the halogen incandescent bulbs are even more power consuming. However, CFLs seem to be obviously a better option than both of the previously mentioned incandescent bulbs. CFLs operate at very les voltage and also take very less power.
When it comes saving electrical power, none of the above can beat the simple, humble and incredibly small LED bulbs. LEDs are very common as we see them in our laptops and computers and all sorts of electrical devices. Whenever you see a small light glowing on your laptop that tells you that the laptop is on at the moment, do remember that there is small LED in there.

The bad thing:
The only problem here is that LEDs are very expensive and constant research is going on to reduce the manufacturing costs of these. For the time being they are too expensive to be used at home and so are used at factories for efficient lighting.
The good thing:
The good thing is that they can last incredibly longer than any of the artificial sources of light. While an incandescent light bulb lasts just 1 year, an LED can last up to 20 years.
The time is not far when we would start using these amazing LED bulbs at our homes too.
