LED lamps and lanterns cost mainly has three parts, respectively is: lamp beads, shell, drive power supply, to keep the price pressure to a minimum, only start from the three places. Lamp bead: China zhongshan guzhen domestic 1 w lights, lowest selling 2 yuan yuan, why such a low price? Because they will light the gold wire in the bead replace with copper wire, and other raw materials using inferior material substitution, and nominal 1 w, but with the equipment testing may only 0. 5W。 These are the general consumer imperceptible.
