Unverified调光方式建议选支持无极调光或多档位（≥3档），并优先PWM调光频率＞3000Hz或采用DC调光的机型，避免低频PWM调光在低亮度下产生频闪92% similarUnverified带亮度调节应做到0-100%无级调光且低亮度不频闪，廉价灯低亮度档常出现PWM频闪，慢门或高帧率拍摄会出现横纹91% similarUnverified补光灯需关注是否无频闪（flicker-free），低质量PWM调光的灯在低亮度档拍摄视频会出现横向滚动条纹，专业拍摄应选择DC调光或高频PWM（≥25kHz）产品90% similarUnverifiedPWM调光频率过低会产生频闪，防蓝光灯带若采用低频PWM调光反而伤眼，选购调光款需确认调光频率≥3000Hz或采用DC恒流无频闪调光90% similarUnverified真正无频闪需认准DC调光而非高频PWM调光，PWM调光频率≥3840Hz才能基本消除频闪对眼睛的影响，低于此值长时间使用易疲劳90% similar
