First: look at the brightness, usually people will say that your lamp beads can reach LM (lumens), LM (lumens) is the unit to measure the brightness of the lamp beads

Second: Check whether the light is uniform and the color is consistent. The high-quality lamp beads emit light evenly and have the same color. Inferior lamp beads will appear one lamp bright and one lamp dim. The color of the light is messy and uneven, and there will be obvious dark areas.

Third: Look at the chip and chip size. The chip is the decisive factor for the quality of the lamp beads. Generally, the larger the chip, the stronger the stability, the higher the brightness, and the better the heat dissipation.

Fourth: Take a look at glue and phosphor. Generally good products will use imported glue, sealed lamp beads will not be deformed by hand, and inferior glue will deform or even break when pressed.

Fifth: Look at the bracket. Generally, the stent is a silver-plated copper stent. The advantage of the silver-plated copper bracket is that it can quickly dissipate heat. Copper bracket, ceramic bracket, with excellent thermal conductivity

Sixth: Look at the packaging process. The high-quality LED lamp beads have uniform color and good colloidal consistency. This is inseparable from good machinery. Production machinery is a key factor. Good equipment can ensure the stability and consistency of the product in various processes and ensure the pass rate of the product.
