Unverified82% confidenceDecision RuleTime unknown
购买时认准灯管为石英玻璃材质而非普通高硼硅，普通玻璃会阻挡大部分254nm紫外线，同时查看是否有质检报告标注实测254nm辐照度

Unverified石英玻璃灯管透UV-C率约90%以上，普通高硼硅玻璃会大幅吸收UV-C；正品灯管应标注石英材质，透明玻璃且点亮时肉眼看不到强烈蓝紫光反而更可靠（纯UV-C几乎不可见，可见强蓝光多为伪劣品混合可见光）80% similarUnverified选购必须核对灯管材质：石英玻璃(透UVC率90%以上)才有效，普通玻璃或UV硬质玻璃透UVC率极低；同时确认有CCC认证及标注UVC辐照强度参数，无参数标注的三无产品杀菌效果无保障79% similarUnverified选用微棱镜（微棱晶格）反光材料，其回归反射亮度是普通玻璃微珠款的2-3倍，夜间被车灯照射时200米外可识别；玻璃微珠款仅适合低速城市路段78% similarUnverified石英灯管的UVC透过率约90%，普通玻璃灯管会大量吸收254nm，选购看灯管材质是否为高硼硅石英玻璃；UVC-LED寿命长但当前功率和杀菌效率仍低于汞灯管77% similarUnverified选膜看透光率标注：优质钢化玻璃膜透光率≥91%，低于88%会明显影响屏幕亮度和清晰度77% similar
