3, the LED with wavelengh consistent wavelengh, color is consistent, if ask color is consistent, criterion the price is high. The manufacturing business of appearance of prismatic without LED color separation produces the product with pure colour very hard.

4, the illuminant that residual current LED is one-way electric conduction, if have retrorse electricity, call leakage of electricity, the LED with big residual current, life is brief, the price is low.
