UL1598 UL Standard for Safety Luminaires
UL1598A Safety Supplemental Requirements for Luminaires for Installation on Marine Vessels
UL1598B Supplemental Requirements for Luminaire Reflector Kits for Installation on Previously Installed Fluorescent Luminaires
UL1598C Subject OUTLINE OF INVESTIGATION FOR LIGHT-EMITTING DIODE (LED) RETROFIT LUMINAIRE CONVERSION KITS

从标题上似乎已经很明确，如果还有疑问去看看Scope。
