LEDs present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching, etc.

(1). Energy efficiency –LED lights produce more light per watt than incandescent bulbs. Energy consumption can be saved between 40% -70% of the conventional lightings.

(2). Long life – These lights can last from 50,000 to 100,000 hours. Incandescent light bulbs typically last around 1,000 hours and fluorescents are good for roughly 10,000 hours.
