There are currently capable of producing LED and LED lighting manufacturers also a few different companies with different quality LED LED lighting is a major reason for the different prices. As the increasingly fierce price war, appearance, structure, function almost the same products, there are two to three times the price difference, many customers were up 1 fainted mind, I do not know where to spread from the general production of LED LED LED lighting manufacturers Are difficult to distinguish, let alone consumers.

Therefore, they have a good selection of LED sources of production, or LED testing equipment has improved the LED Lighting Factory will be better, so bought the LED lighting products will be more secure.

We have to look at what factors caused the price difference between LED lamps:

1, brightness
LED brightness different, different prices. LED lamps used for the LED should be in line with the laser class Ⅰ grading standards.
2, antistatic ability
Antistatic ability of the LED, long life and thus higher prices. Antistatic usually greater than 700 V of the LED can be used for LED lighting.
3, wavelength
The same wavelength LED, the same color, such as the requirements of the same color, the high prices. No Separation-by LED manufacturers to produce products of pure color.
4, leakage current
LED is one-way electrical conductivity of the luminous body, if a reverse current, known as leakage and leakage current large LED, short life expectancy, low prices.
5, luminous point of view
LED uses a different point of view different from its luminescence. Special luminous point of view, the higher prices. If the whole diffuse Kok, higher prices.
6, life
Different quality of life is critical, life-bad decision by. - Failure of small, long life, longer life expectancy, the high prices.
7, LED chips
The luminescence of the LED chip and different chips, prices vary widely. Japan, the United States more expensive chip, the Taiwan plant and the local Chinese manufacturers LED chip prices lower than Japan, the United States.
8, chip size
The size of the chip side said that the LED chip quality is better than small chips. The price is directly proportional to the same size chips.
9, colloidal
Colloidal LED ordinary general epoxy resin, plus a fire and anti-ultraviolet LED prices of the more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.
LED lighting lighting market there are still only part of the illegal, deception providers, fraud suppliers to produce finished materials, not normal to low-cost products to sell for cash. A small number of LED lighting manufacturers to unrealistic promises to deceive dealers and users, and then use ever-changing business or person in charge of the trick to shirk its responsibility.
