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