Unverified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93% similarUnverified单火线智能开关因需从灯具回路取电，容易导致关灯后LED灯微亮或频闪，若家中大量使用低功率LED灯，建议加装辅助电容或直接改零火线方案92% similarUnverified单火线智能开关工作时需从负载取电，接LED灯（功率＜5W）容易出现关灯后微亮、闪烁问题，此时应加装电容或改用零火版；零火版对负载类型无此限制91% similarUnverified单火版智能开关在关灯状态下需微弱电流维持联网，容易导致关灯后灯泡微亮或频闪，尤其LED灯明显；有零线条件时优先选零火版避免此问题90% similarUnverified控制LED灯带、小功率吸顶灯（<10W）不建议用单火线开关，负载过低无法维持单火取电，会导致关不断或闪烁，应改零火方案90% similar
