The LEDs are replacing the old style filament and CFL lights. There are various reasons why people would choose led bulb lights instead of others. The very first thing is the cost effectiveness. The LED bulbs are high power efficient and thus save lots of money which would have spent in the old form of bulbs, otherwise. Another thing is the performance. The LEDs are able to light up much longer as compared to other forms of lights like filament or CFLs. This means that it has very long life as compared to other light bulbs.
Not to forget that LEDS are electronic components which mean that it will not blow off as easily as other do. The LED bulbs are capable of handling a wide range of fluctuations in the power without blowing off. This provides them ultra long life. Also, they never fade up lighting. The major thing is an efficient conversion of eclectic current into light. The other forms of light bulbs also convert large amount of power into heat and IR light which is just the loss of power resources. Finally, the LED lights are able to light up more brightly as compared to other traditional forms of light bulbs.
