Chris,
Go to the following site and it explains it very well with examples. http://www.ul.com/mark/index.html The information not covered are the : product type (e.g., "I.T.E.") (there is a lot of variation allowed here), 4 character "Listing Mark Control Number" (LMCN) which is a confidential ID for the applicant, UL file number when appropriate, use of the word "Accessory" or similar when appropriate, The use of the LMCN and UL File Number is determined by who the Applicant and Listee are and who's name is on the power rating label. Also the little detail that the text must be in all Caps and Bold. Oscar M.O.O.

But please indulge my ignorance. There are many different forms of UL marks, each with subtle differences. There is the "UL" in a circle. There is also the mirror lettered "RU". There are also some subscripts denoting approval for Canada as well. There may be some other variations that I can't remember. Anyone care to blow a few minutes on a Friday afternoon to explain which symbol means what?
