防眩光设计越好（深藏光源、格栅、磨砂罩）光效损失越大，同瓦数下深防眩灯实际亮度比裸灯低20-30%，追求氛围选防眩、追求照度需加大功率

Unverified透光率越高越亮但防眩效果越弱：清透亚克力透光率90%以上几乎无防眩作用，深磨砂/双层扩散罩防眩最好但透光率降至55%左右，需同步提高光源流明补偿87% similarUnverified深防眩设计牺牲出光效率：灯珠越深藏、蜂窝网越密，眩光越低但实际照度衰减越多，需相应提高瓦数补偿；不能既要极致防眩又要小功率省电87% similarUnverified灯光越强、附加除雾/调光功能越多，越暖光越费电且电路复杂故障点越多；仅照明需求选无电感应或简单开关款更耐用省心86% similarUnverified遮光设计（下沉式光源+防眩光板）比单纯高流明更重要，能看到裸露光珠或直视灯头刺眼的灯，即便照度达标也会造成眩光疲劳85% similarUnverified防眩光的核心是降低亮度对比，选择透光率65%-80%的乳白亚克力或PC材质，既能有效柔化光线又不会过度损失照度；透光率低于50%会显著变暗，需增加灯泡功率反而增加能耗85% similar
