Addressing the "conforms to UL standard" issue. Even though UL may set the standard they are not the only NRTL that can list an item as to compliance with the standard.
ETL is just one of many NRTL's out there.
A few more that I see from time to time are CSA, (Canadian Standards Association) ETI, (Electro Test INC) ENT, (Entella) NTS, (National Technical Systems) and more.
