China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The general market electronic ballast of a variety of:

Instant start no preheating electronic ballast:
Instant start without preheating electronic ballasts, lighting the lamp instant start, due to the filament of the bulb-end is exposed to a sudden start voltage, not be long before the lamp filament is extremely easy to cut off, lamp life compared. According to tests, bright put out 35 seconds to 25 seconds, the number of points off only about 2000 to 3000.

Preheat start electronic ballasts:
Preheat start electronic ballasts, circuit design slow start, lighting the lamp for about 1-2 seconds when lit filament of the bulb-end is exposed only to slowly boost start-up voltage, lamp filament is not easy to be broken , the lamp is more long-lasting. According to tests, 35 seconds to 25 seconds put out bright points off the number can be as high as more than 15,000 times.

How does the electronic energy-savinglamp ballast work:
High-frequency conversion circuit with electronic components. The first lighting AC power rectifier current into direct current, high frequency alternating current by the inverter to 20 ~ 50KHz high frequency voltage generated by the oscillator circuit to start and fluorescent light, the adjusted correctly matches the light, to meet the type of the start-up voltage of the power lamp, the lamp voltage and lamp current, to reach normal operating.
