With the rapid development of LED lighting industry, all kinds of lamps and lanterns are blooming and a hundred schools of thought contend with each other. The price difference is also very obvious. The main reason for the difference of LED lamps is that different manufacturers choose different quality LED projectors. Therefore, it is better to choose a good source of LED projection lamp production, or a LED lighting manufacturer with perfect LED detection equipment, so that the purchased LED lamp products will be more secure. In the selection, the following points should be considered:

1. Brightness
LED brightness is different, the price is different.
2. Antistatic capability
Led with strong antistatic ability has a long service life and high price. LED lighting is usually more than 700V antistatic.
3. Wavelength
Led with the same wavelength, if the color is consistent, the price is high. It is difficult for manufacturers without led spectrophotometer to produce pure color products.
4. Leakage current
LED is a one-way conductive light-emitting body, if there is a reverse current, it is called leakage current, led with large leakage current has short life and low price.
5. Luminous angle
Led with different uses has different luminous angles. Special luminous angle, higher price. If full diffuse angle, the price is higher.
6. Life span
The key to different quality is life, which is determined by light decay. Small light attenuation, long life, long life, high price.
7. LED chip
LED luminous body for chip, different chips, the price difference is very big. Chips in Japan and the United States are more expensive, while the prices of LED chips made in Taiwan and China are lower than those in Japan and the United States.
8. Chip size
The size of the chip is indicated by the side length, and the quality of LED on the large chip is better than that on the small chip. The price is proportional to the size of the chip.
9. Colloid
The colloid of ordinary LED is generally epoxy resin, and the LED with anti ultraviolet and fireproof agent is more expensive. High quality outdoor LED lighting should be UV resistant and fireproof.
