Lamp life depends on whether the start ballast is program or instant.
灯寿命取决于启动镇流器是程序式的还是瞬时的。

Based on T type filter, the new ballast can achieve a wide dimming range with a very narrow frequency variation range, and it can operate with low lamp current crest factor.
基于T型滤波器的调光方法，能在很窄的工作频率范围内实现深度调光，同时具有灯电流波峰因数低的优点。
