Major Characteristics Warm-up startup; The filament is preheated to its temperature setting before it starts, and thus the life of operation of the tubes is prolonged. Wide applicability of voltages. High power factors with less resonance waves. Abnormity status protection. The protection function is activated when any abnormal status occur in the load. The lamps have no frequency flash and its good for the visual protection for users. An outstanding energy-saving result. Stable performance and reliable and safe in operation. The Ballast are divided into the following: 6W/8W/11W/13W based on the difference between the nominal power of tubes.
