Why should we choose LED ?

More and more people would prefer LED rather than other original light source. LED are a far more energy efficient, more environmentally friendly and also a cost-saving alternative to the old conventional incandescent and CFL light bulbs

For Vehicles, LEDs use less energy than Halogen and offer a higher output. But before those under 5000 Kelvin LED bulbs come, Halogen keep the position of main choice for cars. That's because white color can't be used as a fog lamp when driving in foggy or raining day. It's dangerous. 

But as known to everybody, LED is more expensive than Halogen. Only one reason to accept the higher price is that, LED makes more color and they own a longer life.
