Light Emitting Diodes (LEDs) have recently entered the lighting market as an energy efficient alternative to traditional light sources such as incandescent (GLS) and fluorescent bulbs (CFL). The ever-increasing demand of LED lights has generated awareness about its advantages over CFLs and incandescent lamps. One of the major advantages of LED over its rival is of lifespan. LED has a lifespan of 25,000 to 50,000 hours whereas for CFL it is 8,000 hours and for incandescent light bulbs it is less than 2,000.
