Why are LED lighting devices better than the traditional ones?

There is a continuous innovation in the display technology. The cathode ray tube based TVs or computer monitors are now giving way to the more advanced display lighting systems. These are the modern day liquid colour display and the light emitting diode technology based display lighting technologies. Companies like Sony are now fast outdating the CRT based display with the flat screen, practical LCD TV or the LED lighting technology based displays.

What makes LED so special? Why is its usage fast outstripping the demand of the CRT displays? There are many advantages which come with the LED. Some of these are the following:

1.Widespread use: LED lighting has been there for some decades now and is therefore a proven technology. Its use is not confined only to the TVs or ,monitors but is also being used extensively in different electronic and lighting devices like bulbs, telephones, and others.LCD TV have life in tens of thousands of hours.

5.Score over CFL: You must not confuse the LED with the CFL lighting devices. The latter contains mercury which makes it necessary to handle it with extreme care. The presence of mercury makes them dangerous to use. These are therefore very environment unfriendly.

6.Do not heat up: The LED lighting devices does not heat up even after using them for several hours. The incandescent lights and the CFL can get hearted within a few minutes but not the LED ones.

7.Constant light throughout their life: The light of the LED devices is of same intensity all through their lifetime. These do not get dim. In fact, they fade only when these are at the end of their very long lifetime.

All these factors make the light emitting diode based lighting devices extremely popular, especially among those who want to reduce their monthly electricity bills as well as are conscious of the damage to environment. These might be more expensive than the traditional ones but when their advantages are considered, these are found to be more practical.
