Unverified85% confidenceFactTime unknown
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

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）86% similarUnverified石英玻璃灯管透UVC率约90%以上且寿命长（约8000-10000小时），普通高硼硅玻璃透过率低衰减快；查看灯管材质是判断真伪杀菌力的关键，纯石英管应无色透明85% similarUnverified石英玻璃灯管透UV-C效率>90%，高硼硅玻璃管衰减明显；灯管为白色/乳白色的多是普通日光波长（假紫外线灯），真UV-C灯管点亮时呈淡蓝紫色且不应直视84% similarUnverified石英玻璃灯管UV-C透过率＞85%，普通高硼硅玻璃透过率低、衰减快；灯管寿命通常8000小时，超期后紫外强度大幅下降需更换，非'不亮才坏'83% similarUnverified认准UVC灯管标注的UVC辐照度（μW/cm²）参数而非仅看总功率，同样36W不同灯管UVC转化效率差异大；国标要求距灯管1m处253.7nm辐照度≥70μW/cm²为合格杀菌灯82% similar
