LED Flexi Strip

 3, the same wavelength wavelength of the LED, the same color, such as requiring the same color, then the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.

4, the leakage current LED is one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, life is short, low prices.

LED Module

5, the use of different LED light-emitting angle of its light angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, higher prices.

6, the life of different quality is the key to life, life determined by the light fades. Light decay, long life, long life, high price.

7, light LED chip the wafer, different chips, prices vary widely. Japan, the United States more expensive chips, generally made in Taiwan and chip prices lower than Japan and the U.S..
