Subject: Different shades of UL



Hi all,

I know that this has been covered before.  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?  

Thanks,

Chris Maxwell | Design Engineer - Optical Division
