This, in turn, led to the demand for compact, high efficiency and low noise LED driver ICs, because of the need of this kind of driver IC for white LED power supply. High-power, high brightness LED light output has exceeded this critical milestone in every Watt100 lumens, and even some manufacturers claim has reached every Watt200 lumen in the laboratory. This means that will be able to effect the purposes of, the LED now has more than the CFL (each Watt80 lumens). However, further projections indicate that in 2012, the LED will reach the each Watt150 lumen light output. Another advantage is the long life of the LED.
