As far as I know, there is only one HLMP-6000. There are many HLMP-6xxx and many with additional letters and numbers after the HLMP-6000 designation; they are all different from the real plain HLMP-6000.
I did a Google and the first few that popped up had different pics and different specs from each vendor. I just wanted to check here first before I bought the wrong part.
Thanks Grainger and PJ
Lately I've seen a number of instances where a vendor's web site has incorrect information. I download the data sheets to make sure I have the exact manufacturer's part number. No data sheet available = no money from me!
