LED产品的*是材料, 工艺很重要，但是如果您对价格*敏感，材料则尤为关键， 其他都*马=浮云

 ==> *先材料决定品质；巧妇难为无米之炊 LED产品是一分价钱一分货的 买卖

便宜的LED产品*对好不到哪里去，但 高价未*能有买到好东西，如何拥有一双慧眼？

 

单说LED 灯珠， 一颗灯 价格从五分，1毛，3毛，1.5元 不等，而外观却无明显差异，点亮肉眼辨别更是雾里看花！！

 

同样：电源，电线，PCB, IC，灌胶，铝型材，控制器，套件等 品质价格差异 也会*出一般人的想象：

 

例如电源： 5V 40A, 有30 50元一台， 70 80元一台， 有135元一台，也有230元一台 (什么品牌？国产？*？如何辨别真假？)

例如电线：纯铜？ 还是再生铜？ 普通套胶还是*火阻燃？

例如IC: 1元一个？ 还是2元一个？ 也有7 8毛一个的

例如驱动设计：是灯驱动分离？ 还是灯驱动合一， 外观一样，价格可就差很多了

 

这些一般人非经长时间业内实践或 仪器而不能*辨别
