Why downlight will sound, how to remove the sound
You may buy is a low voltage bulb lamp, is equipped with a voltage transformer, if you use 220V bulbs, will not have these troubles. Because, if the voltage transformer quality is not very good, it will produce current sound, the transformer core, the greater the gap between the steel plate, the greater the sound. Regardless of the quality of the transformer is good or bad, in fact, it will produce current sound, just big and small, high and low, the quality of the transformer, sound can be very weak, and negligible.
Will you get a fake? PHILPS on the Internet, a lot of fake. There is no sound downlight, estimated sound is a transformer, the general situation is the core of transformer steel sheet is not tight, a transformer is good.
If the wiring and voltage are all right, there is a problem with this batch of lights. It's probably not genuine.
