non-isolate led power supply led driver 220v ac 30w 35w dc with plastic housing, follow EN61347-1;EN61347-2-13.
High efficiency
For power supply installed in the structure of the lamp is particularly important because the LED luminous efficiency with the LED temperature rise and down, so the LED heat is very important. High efficiency, its power consumption is small, the heat in the lamp is small, it will reduce the temperature rise of the lamp, to delay the LED light failure beneficial.
