  • After the magnetic gap is padded with appropriate padding, stick it with adhesive and wrap it with high temperature resistant and flame retardant adhesive tape to prevent it from becoming loose. In addition, do not connect the same end of B incorrectly. Maintenance of the electronic ballast using the trigger tube, should focus on checking the bidirectional trigger diode, this tube generally uses DB3 type, its bidirectional breakdown voltage is 32±4V. In terms of technology, LED lamps and ordinary energy-saving lamps, each have advantages, in a certain period of time, should not replace energy-saving lamps; However, the cost of LED lamp will decrease with the continuous improvement of LED technology.
