Question:

I have LED lights on fluorescent lamp tubes, and I have tested five times a dc

I have LED lights on the fluorescent lamp, and I tested it when I was running five times a dc, and four LED lights were very bright and hot,

Answer:

No good. 220v is a valid value. The maximum value is 310v, and it burns instantly.I hope my answer will help you.
Let's say a light bead is working at 3v voltage and the current is 300ma. To get it to 3.1 volts, the current can reach 400ma. 220v market volatility is large (200-250) sometimes higher. At the very least, you need to add resistance.
But I'm very weak with five of these five, and I'm supposed to say that one 1.25 volts, 176 times and 1.25 is 220 volts,
