求教:IEZR和IEZX
各位有谁知道UL1598里面的IEZR和IEZX是指什么灯呢?谢啦 IEZR 和 IEZX 为UL 的category number，用于标识产品类型。以下为部分cat num对应的灯具（有时候后面带数字7代表cUL）：Incandescent surface mounted luminaires IEZR
Incandescent recessed luminaires IEZX
Fluorescent surface mounted luminaires IEUZ
Fluorescent recessed luminaires IEVV
High intensity discharge surface mounted luminaires IEXT
High intensity discharge recessed luminaires IEXZ
Incandescent recessed luminaires, convertible - non IC/IC IFAH
Canopy luminaires IFAW
Luminaires, portable QOWZ 一直有疑惑
现在终于明白了！
