Power supply connection method: The general voltage of the LED light strip is DC 12V, so you need to use a switching power supply. The size of the power supply is determined by the power of the LED light strip the connection length. If you do want to control each LED light strip with a power supply, you can purchase a relatively large switching power supply as the total power supply, then connect all the LED light strip input power sources in parallel (if the wire size is enough, you can extend it) Uniformly supplied by the main switching power supply. Such an advantage is that it can be controlled centrally, the inconvenience is that the lighting effect switch control of a single LED strip cannot be achieved. The specific method can be measured by yourself.

     Analysis of electrical inspection standards for led light strip manufacturers

(1) Single-color LED lamp with no chip is bright slightly bright.

(2) The R / G / B groups of the RGB lights are powered on tested separately.

(3) Each batch was sampled for 8 hours, there was no electrical defect.

(4) After the bending, winding vibration damage experiments, there is no electrical failure.

(5) No electrical defect is detected after the high low temperature extreme temperature resistance test (-20 ℃ ~ 80 ℃).

(6) Waterproof LED lights with visual protection level, tested separately for waterproof experiments, no electrical failure

     With the advent of LEDs, the lighting design theory continues to evolve with the advantages of LEDs. LED light strips are also gradually being widely used in industries such as interior lighting, building decoration car beauty. However, the market for LED light strips is mixed, the prices of regular LED light strip manufacturers cottage products are very different. If the quality of LED strips is identified professionally, I am afraid that many customers do have this ability. However, we can make a preliminary identification of the LED strip according to the following standards, basically distinguish the quality.
