The low current starts quickly and outperforms the imported ballast. The cold current is not excessive, and the lamp tube is not accelerated to a high level, which extends the life of the lamp tube. Using advanced electronic ignition technology, the high-voltage output is stable, with less interference, and strobe up to 10 million without damage. The imported ballast design is used, with ultra-fast ballast + frequency conversion decoder or X3 decoder, D1 / D2 / D3 / D4 installation, to meet the installation of different models.
