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

Second: see if the light is uniform and the color is consistent. Good quality lamp beads emit light uniformly and the color is consistent. Poor quality lamp beads will have the phenomenon that one lamp is bright and one lamp is dark. The luminous color is messy and uneven, and there will be obvious dark areas.

Third: Look at the chip and chip size. The chip is the determining 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: Look at the glue and fluorescent powder, generally good products will use imported glue, the sealed lamp beads will not be deformed by hand, and low-quality glue will deform or even crack when pressed.

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

Sixth: Look at the packaging process. Good quality LED lamp beads have uniform color and good colloid consistency. This is inseparable from good machinery and equipment. Production machinery and equipment is a key factor. Good equipment can ensure the stability and consistency of the product in various procedures and ensure the product's yield.
