We make resin filled in every point of the electrical parts to make sure no water can go inside to damage the lamps. Resin is used for the wire-in, driver, PCB board, etc.
The quality of the resin glue is very important. We use the top glue brand in China, it has very good adhesion, non-toxic to the LEDs, anti-reduction to make sure no liquid is converted from the air, due to protects the electrical parts from damage.
Another important process is our testing part. We make all the lamps tested underwater before the package. For every order, we take 10% out of the total quantity and do pressure testing under 15 meters of water depth(testing machine to simulate.
All these tests can ensure every led pool light is in good IP68 waterproof condition before sending it out.
