The ordinary fluorescent lamp in the home is on the Internet say to remove the hui, the ballast part is short, put on LED lamp tube, can connect to change 3 lamp tube not bright?
The problem should be: 1, your lamp holder is not in position; 2, the connection of the lamp holder is loose or the wire is broken. No short circuit at both ends of the rectifier. No short circuit in place on both ends of the rectifier, easily between the open flashing voltage is too high, if the LED lamp circuit withstand voltage protection, easy to damage, so suggest tear down ballast, connect the line again.
Tear down, the starter of the ballast two wires together is short circuit, and then mount LED bulb, then spin the tubes card in place, above if no problem, so there is no possibility of three light tube is not bright.
The wind tube of the ballast is usually not flashing when it is opened, and the life span is basically one year
