How waterproof and breathable plugs work in LED lights

The waterproof and breathable plug is a polymer material with a special structure, which is composed of a waterproof layer and a breathable layer. When water droplets contact the waterproof layer, the waterproof layer will block moisture from entering the interior of the LED light. At the same time, due to the existence of the breathable layer, the internal hot air can be discharged to maintain a dry environment inside the LED lamp. The main feature of this stopper is that it can balance the internal and external pressure, prevent water vapor from penetrating into the inside of the package, while allowing gas to escape, keeping the inside of the package dry.
