Which factors determine the LED bulbs price

     LED lighting industry in today's increasingly fierce competition, some manufacturers have launched a price war. In the market, appearance, structure and function of almost the same product, the price difference is 2-3 times, most consumers know the reason, unless the professional manufacturer, it is generally difficult to distinguish.
     What's causes the different of LED bulbs price?
     1, brightness.
LED bulbs use LED light source of different brightness, the price is different.
     2, lifetime is different.
Lifetime is decided by the light fades. Light a small decline, long life, high price.
     3, antistatic ability.
     Antistatic ability of LED bulb is strong, the life is long, thus the high price. Anti static than 700V LED can be used for LED lamp.
     4, the wavelength.
     The same wavelength LED, the color is same, such as requiring the same color, the price is high. No LED spectrophotometric color instrument manufacturer is very difficult to produce pure color products.
     5, the LED chip.
     LED bulb luminous body is chip, different chips, prices vary widely. Japan, the United States more expensive chips, Taiwan plant with China's domestic manufacturers of LED chip prices lower than Japan, the United States.
     6, the chip size.
The quality of big chip LED is better than small chip LED. The price is high.
     7, the leakage current.
     LED is a one-way conductive light, if there is reverse current is called leakage, the leakage current is large, short life, low prices.
     8, the light emitting angle.
     Different uses LED light emission angle is not the same. Special light angle, the higher the price. If all diffusion angle, higher prices.
     9, colloid.
     Ordinary LED colloidal is epoxy resin, have anti-UV and fire retardant of LED, the higher the price, high-quality outdoor LED lighting should be UV and fire.
