5, wavelength
Wavelength consistent LED, color consistent, then the price is high. Producers who do not have LED spectrophotometers are difficult to produce pure color products.
6, leakage current

LED luminous body for the chip, different chips, the price difference is very large. Japan, the United States more expensive chip, Taiwan and China's domestic manufacturers of LED chip prices lower than Japan, the United States.
8, chip size
The size of the chip to side length, large chip LED quality is better than the small chip. The price is proportional to the chip size.
