1. The requirements for brightness are different for different occasions and different products. For example, if the LED jewelry table lamp is placed in some large shopping malls, we need to have a higher brightness to be attractive, and the same decorative function is also divided into different products such as LED spotlights and LED colorful light strips.
2. Antistatic ability: LED with strong antistatic ability has a long life, but the price will be higher. The general antistatic is generally higher than 700V.
3. LEDs with the same wavelength and color temperature will have the same color. This mass combination of lamps is particularly important. Do not cause too much color difference in the same lamp.
4. Leakage current is the current when the LED conducts reversely. We recommend using LED products with a smaller leakage current.
5. Waterproof ability, the requirements for outdoor and indoor LED lights are different.
6. The light-emitting angle of LED has a great influence on high-power external LED lamps, and it has great requirements for different lamps. Like LED fluorescent lamps, we recommend using 140-170 degrees. We will not elaborate on the others here.
7. LED chips determine the center quality of LEDs. There are many brands of LED chips, including foreign brands (such as CREE, Nichia, etc.), and Taiwan, China (such as Guanggal, Epistar, etc.). The prices of different brands are also very different.
8. The size of the LED chip also determines the quality and brightness of the LED. We also try to choose a larger chip when choosing, but the price is also different.
