Transformer used in electronic components, the design determines the efficiency of the transformer, power factor, stability, temperature rise, life.Users who do not understand the LED Light components knowledge, can be judged from the initial size of the transformer, weight, and electrolytic capacitors, consult the manufacturer's terms of use. For the differences of LED Bulb prices, the quality of the transformer is not a small proportion. 3, understand the brand and packaging: Lamp beads quality decide the LED ceiling lighting effect, packaging technology affect the quality of lamp beads, heat dissipation and so on. myledgrowupanty 141023
