Doug, There is so much confusion and inaccuracy out there on this topic I could 
write a book on it.  The majority of the OEM spec sheets I deal with do not 
have the compliance information clearly identified and mix up the difference 
between actual NRTL approvals and the standards.  I can only hope when the put 
the NRTL artwork mark on the data sheets that the product is actually 
certified/listed.  Otherwise when they just list a UL standard under 
“approvals” I have to confirm who actually certified it.

Just this week I had to explain to one of my supplier OEM product managers, 
that no, their product is not UL listed, it is ETL certified to a UL standard.  
Their documentation is clear and correct but they’ve been verbally 
communicating it was “UL listed”.  I sometimes act as an intermediary between 
Intertek and my OEM, having pointed them to Intertek.

Subject: [PSES] Listing confusion

All,

Well actually, I'm not confused. But I'm certain some consumers are.

I ran across an LED lighting fixture product and they were promoting "ETL and 
DLC Listed", of course I became curious. DLC is a consortium about energy 
efficiency and in this company's view DLC gets top billing along with ETL 
safety certification. DLC has been around for some time and possibly this is 
the first time I've seen the two promoted in this manner, but it got my 
attention. Some companies ethically make the distinction that DLC is not a 
safety certification while others do not.

Maybe I'm blowing this all out of proportion and possibly I'm becoming 
territoriality minded, I simply don't want other people treading on my safety 
certs soil and that said we certainly don't have exclusive use of the generic 
word "listed". I simply don't like the phrase DLC Listed. I've seen this sort 
of thing before when acronyms are added to product labeling a little like 
NASCAR racing stickers or all the special labeling for food and shampoo, that 
is when it is used as a sales tool. Of course, the more acronyms and symbols 
you add to a product the better it is, right?  Maybe someday we'll have 
fat-free, range-free, non-GMO, fair trade, gluten free, grass fed, humanely 
handled, made from recycled HDPE lighting products... or maybe not.

Here is that DLC link, https://www.designlights.org/

Happy Friday and best to all, Doug
