遮光率行业分级参考：柔光/透光30-50%、半遮光60-85%、遮光90-95%、全遮光99%以上（blackout）。标称'遮光'但仅达85%的产品仍会明显透光，选购时应认准具体百分比而非仅看'遮光'二字

Unverified遮光率的行业口径不统一，'物理遮光率'（挡光比例）与'遮光等级'（分级标准）不同；国标GB/T中遮光窗帘遮光率一般以≥60%为遮光帘门槛，'全遮光'通常指≥99%，购买时应看具体百分比而非营销词91% similarUnverified遮光率≥90%的静电吸附遮阳帘才能有效阻挡紫外线，普通网纱蜂窝帘遮光率多在60-75%只能挡强光眩光82% similarUnverified评估亮度时应关注最低亮度档位的调节精度：仅有5%-10%档位跨度的灯在近距离美食/产品微距拍摄时最暗档仍过曝，需选支持0-100%无级或1%精细调光的型号80% similarUnverified遮光率约50-70%属于半透光级别，主要削弱眩光而非完全遮黑，追求午休全暗环境的不适合80% similarUnverified透光率标称99%以上多为营销话术，普通钢化玻璃基材透光率上限约92%，真正区分高低端的是有无雾面处理和涂层均匀度，看参数不如实测防眩光80% similar
