EspañolLED size: Different specifications and sizes of LEDs have different prices. For example, the prices of 0603 LEDs and 1210 (ie 3528) LEDs differ greatly; and the prices of 1210 and 5050 LEDs differ by another level.
Look at the cleanliness of the surface of the LED strip. If the LED light strip produced by SMT process is used, the surface cleanliness is very good, and no impurities and stains can be seen. However, if the counterfeit LED light strip produced by hand-soldering process, no matter how the surface is cleaned, there will be stains and traces of cleaning, and at the same time there will be flux and tin slag residues on the FPC surface.
Look at the packaging. Formal LED light strips will be packaged in anti-static rolls, usually 5 meters or 10 meters, and then sealed with anti-static and moisture-proof packaging bags. The counterfeit version of the LED light strip uses recycled reels to save costs, and there is no anti-static and moisture-proof packaging bag. If you look closely at the reels, you can see the marks and scratches left when the labels were removed.
look at the label. Regular LED strip packaging bags and reels will have printed labels instead of printed labels. However, the label of the counterfeit version is printed, and the specifications and parameters are not uniform.
see Attachment. Regular LED light strips will have instructions for use and light strip specifications attached to the packaging box, and will also be equipped with LED light strip connectors or card holders; while counterfeit LED light strips do not have these accessories in the packaging box, because After all, some manufacturers can save as much as they can.

What are the precautions for LED strip installation?
Precautions for LED strip installation: Wiring method of LED strip The general voltage of the LED strip is 12V DC, so a switching power supply is required for power supply. The size of the power supply is determined according to the power and connection length of the LED strip. The wiring of the single-color 5050 SMD LED light strip is to distinguish the positive and negative poles. Generally, we provide a welded power plug, just plug it directly into the light strip power supply we provide, and then connect all the LED light strips to the power supply. They are connected in parallel, and are powered by the general switching power supply. Precautions for LED strip installation: Controller connection method LED marquee strips and RGB illusion strips need to use the controller to achieve changing effects, when wiring.
