    Is it normal that the surface temperature of the triac dimmable led driver is very high

    A few of our customer confused that the surface temperature is very high ( After 48 hours of operation, the temperature reaches about 82.2°) of our triac dimmable led driver. Is it due to poor quality? Is it due to poor quality? Most people would think so, but the opposite is true. In order to dissipate heat, our led driver will be filled with silicone on the top of the shell. After the glue is ap...
