5730 SMD LED Warm White Super Bright Amazon

The mainstream of LED lighting sources will be high-brightness white LEDs, which are made by 5730 White SMD LED, 5050 White SMD LED, 2835 White SMD LED ect. At present, commercialized white LEDs are mostly two-wavelength, which is a blue light single chip and a YAG yellow phosphor are mixed to generate white light. In the future, three-wavelength white LEDs are more promising, which is inorganic ultraviolet light chips and red, blue, and green three-color phosphors are mixed to produce white light. It will replace fluorescent lamps, compact energy-saving fluorescent bulbs, and LED backlights.

Most of 5730 white SMD LED buyer didn't have a full set of LED professional testing equipment like the LED factory. Then How to identify the quality of 5730 SMD LED without the testing equipment? Here we go~

The best connector for the polarity is the gold wire. After we know that, we can see the SMD LED (or through-hole LED) form the top. There will be a tinny wire inside the White SMD LED, if the color of wire is gold, then that will be great! if it is red (or orange), that means the connector is copper. If it is silvery (or white), that means the connector is aluminum. With the time goes, the silvery connector will getting black.

The long-term impact of large current will largely greatly reducing the service life and brightness if the raw material is poor (like silvery connector or copper connector).
