1: look at packaging.
Regular LED lamp belt will use anti-static coil disc packaging, usually 5 meters a roll or 10 meters a roll, and then use anti-static moisture-proof packaging seal again outside. The shanzhai leds will bring because of cost savings, and use recycled coil plate, then no anti-static moisture-proof packaging bags, see coil plate can see appearance with clear label and tracks when cut.
2: read labels.
Regular LED lamp belt bags will be printed labels and coil plate, rather than the printed label. The shanzhai tags are printed, at the same time, do not have a unified specifications and parameters.
3: look at the attachment.
Regular LED lights inside the belt will be included in the enclosed instructions and lamp specification, at the same time also can equipped with leds with connector or booth; The shanzhai leds with cartons would not have these attachments, because some manufacturer, after all, still can save a province.
4: the solder joints
Regular LED lamp belt manufacturer of LED lights is to use SMT process, with solder paste and reflow soldering process. Therefore, leds solder joints of the belt is smooth and solder amount not much, solder joint circular arc shaped from the FPC welding plate electrode to LED in extension. Amount of solder solder and shanzhai leds with uneven, is one more dot encase leg , will have different degree of icicles appears at the same time, this is a typical phenomenon of manual welding.
