Unverified单火线智能开关不建议控制LED灯/吸顶灯等小功率负载：单火取电会导致灯关不断电、微亮或频闪，除非加装电容补偿或选支持小功率的型号90% similarUnverified单火版调光开关带负载有下限要求（常见需≥5W~10W），带单颗小功率LED灯时易出现关不断、残光或闪烁；单灯负载过小的场景应选零火版或加装匹配电容86% similarUnverified接LED灯时若出现关灯后微亮/闪烁，是单火线感应开关取电导致，解决路径：优先换零火版→无法换线则并联电容(如1uF)或加装LED镇流器→仍不行改用带零线继电器款86% similarUnverified单火版智能开关依靠微弱电流维持自身供电，容易导致关灯后灯具微亮或频闪，尤其搭配LED节能灯（功率＜5W）时更明显。若不能改零线又要用LED，需加装'防频闪电容/镇流器'，或优选零火版85% similarUnverified单火版开关最低维持电流问题：搭配LED灯（尤其≤5W小功率灯）易出现关灯后微亮或频闪，此时应选零火版或加装电容/镇流器85% similar
