If you find high lamp mode to be too bright for your room, which is quite likely if you have good light control, low lamp mode can help curtail lumen output to a more reasonable level.

如果您发现高灯泡模式过于你的房间，这是很有可能，如果你有良好的光线控制，低灯模式可以帮助减少流明光明输出到一个较合理的水平。

It operates both in current mode at high output load and in pulse frequency modulation (PFM) at light load to reduce the power dissipation.

它在重载下工作于电流控制模式，轻载下工作于脉冲频率调制(PF M)模式来降低功耗。
