Excuse me: DC12VLED advertising lights, power 220V into the line, FireWire line with zero line connection will burn down the power supply?
the LED tube is directly connected to what is electricity, but a comprehensive point is as long as the voltage is not too high is not bad
No, AC is strictly negativeChasing the answerYou can do it anywhereAskPro, not plug, is wiring, and marked the zero line, FireWire pile head.Chasing the answerNo, the zero line is marked in order to distinguish the direction of LED, because
LED is led, since it is a diode having a single conductivity, reverse the equivalent short-circuit (voltage range), alternating current in the reverse will be bright, after rectified DC reverse after is not too bright so you see,
